delivered the opinion of the Court.
The question presented by these cases is whether, consistent with the Equal Protection Clause of the Fourteenth Amendment, Texas may deny to undocumented school-age children the free public education that it provides to children who are citizens of the United States or legally admitted aliens.

Since the late 19th century, the United States has restricted immigration into this country. Unsanctioned entry into the United States is a crime, 8 U. S. C. § 1325, and those who have entered unlawfully are subject to deportation, 8 U. S. C. §§ 1251,1252 (1976 ed. and Supp. IV). But despite the existence of these legal restrictions, a substantial number of persons have succeeded in unlawfully entering the United States, and now live within various States, including the State of Texas.
In May 1975, the Texas Legislature revised its education laws to withhold from local school districts any state funds for the education of children who were not “legally admitted” into the United States. The 1975 revision also authorized local school districts to deny enrollment in their public schools to children not “legally admitted” to the country. Tex. Educ. Code Ann. §21.031 (Vernon Supp. 1981).1 These cases involve constitutional challenges to those provisions.
*206 No. 80-1538
Plyler v. Doe
This is a class action, filed in the United States District Court for the Eastern District of Texas in September 1977, on behalf of certain school-age children of Mexican origin residing in Smith County, Tex., who could not establish that they had been legally admitted into the United States. The action complained of the exclusion of plaintiff children from the public schools of the Tyler Independent School District.2 The Superintendent and members of the Board of Trustees of the School District were named as defendants; the State of Texas intervened as a party-defendant. After certifying a class consisting of all undocumented school-age children of Mexican origin residing within the School District, the District Court preliminarily enjoined defendants from denying a free education to members of the plaintiff class. In December 1977, the court conducted an extensive hearing on plaintiffs’ motion for permanent injunctive relief.
*207In considering this motion, the District Court made extensive findings of fact. The court found that neither §21.031 nor the School District policy implementing it had “either the purpose or effect of keeping illegal aliens out of the State of Texas.” 458 F. Supp. 569, 575 (1978). Respecting defendants’ further claim that §21.031 was simply a financial measure designed to avoid a drain on the State’s fisc, the court recognized that the increases in population resulting from the immigration of Mexican nationals into the United States had created problems for the public schools of the State, and that these problems were exacerbated by the special educational needs of immigrant Mexican children. The court noted, however, that the increase in school enrollment was primarily attributable to the admission of children who were legal residents. Id., at 575-576. It also found that while the “exclusion of all undocumented children from the public schools in Texas would eventually result in economies at some level,” id., at 576, funding from both the State and Federal Governments was based primarily on the number of children enrolled. In net effect then, barring undocumented children from the schools would save money, but it would “not necessarily” improve “the quality of education.” Id., at 577- The court further observed that the impact of §21.031 was borne primarily by a very small subclass of illegal aliens, “entire families who have migrated illegally and — for all practical purposes — permanently to the United States.” Id., at 578.3 Finally, the court noted that under current laws and practices “the illegal alien of today may well be the legal alien of tomorrow,”4 and that without an education, these undocu*208mented children, “[a]lready disadvantaged as a result of poverty, lack of English-speaking ability, and undeniable racial prejudices,. . . will become permanently locked into the lowest socio-economic class.” Id., at 577.
The District Court held that illegal aliens were entitled to the protection of the Equal Protection Clause of the Fourteenth Amendment, and that §21.031 violated that Clause. Suggesting that “the state’s exclusion of undocumented children from its public schools . . . may well be the type of invidiously motivated state action for which the suspect classification doctrine was designed,” the court held that it was unnecessary to decide whether the statute would survive a “strict scrutiny” analysis because, in any event, the discrimination embodied in the statute was not supported by a rational basis. Id., at 585. The District Court also concluded that the Texas statute violated the Supremacy Clause.5 Id., at590-592.
The Court of Appeals for the Fifth Circuit upheld the District Court’s injunction. 628 F. 2d 448 (1980). The Court of Appeals held that the District Court had erred in finding the Texas statute pre-empted by federal law.6 With respect to *209equal protection, however, the Court of Appeals affirmed in all essential respects the analysis of the District Court, id., at 454-458, concluding that § 21.031 was "constitutionally infirm regardless of whether it was tested using the mere rational basis standard or some more stringent test,” id., at 458. We noted probable jurisdiction. 451 U. S. 968 (1981).
No. 80-1934
In re Alien Children Education Litigation
During 1978 and 1979, suits challenging the constitutionality of §21.031 and various local practices undertaken on the authority of that provision were filed in the United States District Courts for the Southern, Western, and Northern Districts of Texas. Each suit named the State of Texas and the Texas Education Agency as defendants, along with local officials. In November 1979, the Judicial Panel on Multi-district Litigation, on motion of the State, consolidated the claims against the state officials into a single action to be heard in the District Court for the Southern District of Texas. A hearing was conducted in February and March 1980. In July 1980, the court entered an opinion and order holding that §21.031 violated the Equal Protection Clause of the Fourteenth Amendment. In re Alien Children Education Litigation, 501 F. Supp. 544.7 The court held that “the absolute deprivation of education should trigger strict judicial scrutiny, particularly when the absolute deprivation is the result of complete inability to pay for the desired benefit.” Id., at 582. The court determined that the State’s concern for fiscal integrity was not a compelling state interest, id., at 582-583; that exclusion of these children had not been shown to be necessary to improve education within the State, id., at 583; and that the educational needs of the children statutorily excluded were not different from the needs of children not excluded, ibid. The court therefore concluded that *210§21.031 was not carefully tailored to advance the asserted state interest in an acceptable manner. Id., at 583-584. While appeal of the District Court’s decision was pending, the Court of Appeals rendered its decision in No. 80-1538. Apparently on the strength of that opinion, the Court of Appeals, on February 23,1981, summarily affirmed the decision of the Southern District. We noted probable jurisdiction, 452 U. S. 937 (1981), and consolidated this case with No. 80-1538 for briefing and argument.8

The Fourteenth Amendment provides that “[njo State shall . . . deprive any person of life, liberty, or property, without due process of law; nor deny to any person mthin its jurisdiction the equal protection of the laws.” (Emphasis added.) Appellants argue at the outset that undocumented aliens, because of their immigration status, are not “persons within the jurisdiction” of the State of Texas, and that they therefore have no right to the equal protection of Texas law. We reject this argument. Whatever his status under the immigration laws, an alien is surely a “person” in any ordinary sense of that term. Aliens, even aliens whose presence in this country is unlawful, have long been recognized as “persons” guaranteed due process of law by the Fifth and Fourteenth Amendments. Shaughnessy v. Mezei, 345 U. S. 206, 212 (1953); Wong Wing v. United States, 163 U. S. 228, 238 (1896); Yick Wo v. Hopkins, 118 U. S. 356, 369 (1886). Indeed, we have clearly held that the Fifth Amendment protects aliens whose presence in this country is unlawful from invidious discrimination by the Federal Government. Mathews v. Diaz, 426 U. S. 67, 77 (1976).9
*211Appellants seek to distinguish our prior cases, emphasizing that the Equal Protection Clause directs a State to afford its protection to persons within its jurisdiction while the Due Process Clauses of the Fifth and Fourteenth Amendments contain no such assertedly limiting phrase. In appellants’ view, persons who have entered the United States illegally are not “within the jurisdiction” of a State even if they are present within a State’s boundaries and subject to its laws. Neither our cases nor the logic of the Fourteenth Amendment supports that constricting construction of the phrase “within its jurisdiction.”10 We have never suggested that the class of persons who might avail themselves of the equal protection guarantee is less than coextensive with that entitled to due process. To the contrary, we have recognized *212that both provisions were fashioned to protect an identical class of persons, and to reach every exercise of state authority.
“The Fourteenth Amendment to the Constitution is not confined to the protection of citizens. It says: ‘Nor shall any state deprive any person of life, liberty, or property without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.’ These provisions are universal in their application, to all persons within the territorial jurisdiction, without regard to any differences of race, of color, or of nationality; and the protection of the laws is a pledge of the protection of equal laws.” Yick Wo, supra, at 369 (emphasis added).
In concluding that “all persons within the territory of the United States,” including aliens unlawfully present, may invoke the Fifth and Sixth Amendments to challenge actions of the Federal Government, we reasoned from the understanding that the Fourteenth Amendment was designed to afford its protection to all within the boundaries of a State. Wong Wing, supra, at 238.11 Our cases applying the Equal Protection Clause reflect the same territorial theme:12
*213“Manifestly, the obligation of the State to give the protection of equal laws can be performed only where its laws operate, that is, within its own jurisdiction. It is there that the equality of legal right must be maintained. That obligation is imposed by the Constitution upon the States severally as governmental entities, — each responsible for its own laws establishing the rights and duties of persons within its borders,” Missouri ex rel. Gaines v. Canada, 305 U. S. 337, 350 (1938).
There is simply no support for appellants’ suggestion that “due process” is somehow, of greater stature than “equal protection” and therefore available to a larger class of persons. To the contrary , each aspect of the Fourteenth Amendment reflects an elementary limitation on state power. To permit a State to employ the phrase “within its jurisdiction” in order to identify subclasses of persons whom it would define as beyond its jurisdiction, thereby relieving itself of the obligation to assure that its laws are designed and applied equally to those persons, would undermine the principal purpose for which the Equal Protection Clause was incorporated in the Fourteenth Amendment. The Equal Protection Clause was intended to work nothing less than the abolition, of all caste-based and invidious class-based legislation. That objective is fundamentally at odds with the power the State asserts here to classify persons subject to its laws as nonetheless excepted from its protection.
*214Although the congressional debate concerning §1 of the Fourteenth Amendment was limited, that debate clearly confirms the understanding that the phrase “within its jurisdiction” was intended in a broad sense to offer the guarantee of equal protection to all within a State’s boundaries, and to all upon whom the State would impose the obligations of its laws. Indeed, it appears from those debates that Congress, by using the phrase “person within its jurisdiction,” sought expressly to ensure that the equal protection of the laws was provided to the alien population. Representative Bingham reported to the House the draft resolution of the Joint Committee of Fifteen on Reconstruction (H. R. 63) that was to become the Fourteenth Amendment.13 Cong. Globe, 89th Cong., 1st Sess., 1033 (1866). Two days later, Bingham posed the following question in support of the resolution:
“Is it not essential to the unity of the people that the citizens of each State shall be entitled to all the privileges and immunities of citizens in the several States? Is it not essential to the unity of the Government and the unity of the people that all persons, whether citizens or strangers, within this land, shall have equal protection in every State in this Union in the rights of life and liberty and property?” Id., at 1090.
Senator Howard, also a member of the Joint Committee of Fifteen, and the floor manager of the Amendment in the Senate, was no less explicit about the broad objectives of the Amendment, and the intention to make its provisions applicable to all who “may happen to be” within the jurisdiction of a State:
*215“The last two clauses of the first section of the amendment disable a State from depriving not merely a citizen of the United States, but any person, whoever he may be, of life, liberty, or property without due process of law, or from denying to him the equal protection of the laws of the State. This abolishes all class legislation in the States and does away with the injustice of subjecting one caste of persons to a code not applicable to another. . . . It will, if adopted by the States, forever disable every one of them from passing laws trenching upon those fundamental rights and privileges which pertain to citizens of the United States, and to all persons who may happen to be within their jurisdiction” Id., at 2766 (emphasis added).
Use of the phrase “within its jurisdiction" thus does not detract from, but rather confirms, the understanding that the protection of the Fourteenth Amendment extends to anyone, citizen or stranger, who is subject to the laws of a State, and reaches into every corner of a State’s territory. That a person’s initial entry into a State, or into the United States, was unlawful, and that he may for that reason be expelled, cannot negate the simple fact of his presence within the State’s territorial perimeter. Given such presence, he is subject to the full range of obligations imposed by the State’s civil and criminal laws. And until he leaves the jurisdiction — either voluntarily, or involuntarily in accordance with the Constitution and laws of the United States — he is entitled to the equal protection of the laws that a State may choose to establish.
Our conclusion that the illegal aliens who are plaintiffs in these cases may claim the benefit of the Fourteenth Amendment’s guarantee of equal protection only begins the inquiry. The more difficult question is whether the Equal Protection Clause has been violated by the refusal of the State of Texas to reimburse local school boards for the education of children who cannot demonstrate that their presence within the *216United States is lawful, or by the imposition by those school boards of the burden of tuition on. those children. It is to this question that we now turn.
HH HH
The Equal Protection Clause directs that “all persons similarly circumstanced shall be treated alike.” F. S. Royster Guano Co. v. Virginia, 253 U. S. 412, 415 (1920). But so too, “[t]he Constitution does not require things which are different in fact or opinion to be treated in law as though they were the.same.” Tigner v. Texas, 310 U. S. 141, 147 (1940). The initial discretion to determine what is “different” and what is “the same” resides in the legislatures of the States. A legislature must have substantial latitude to establish classifications that roughly approximate the nature of the problem perceived, that accommodate competing concerns both public and private, and that account for limitations on the practical ability of the State to remedy every ill. In applying the Equal Protection Clause to most forms of state action, we thus seek only the assurance that the classification at issue bears some fair relationship to a legitimate public purpose.
But we would not be faithful to our obligations under the Fourteenth Amendment if we applied so deferential a standard to every classification. The Equal Protection Clause was intended as a restriction on state legislative action inconsistent with elemental constitutional premises. Thus we have treated as presumptively invidious those classifications that disadvantage a “suspect class,”14 or that impinge upon *217the exercise of a “fundamental right.”15 With respect to such classifications, it is appropriate to enforce the mandate of equal protection by requiring the State to demonstrate that its classification has been precisely tailored to serve a compelling governmental interest. In addition, we have recognized that certain forms of legislative classification, while not facially invidious, nonetheless give rise to recurring constitutional difficulties; in these limited circumstances we have sought the assurance that the classification reflects a reasoned judgment consistent with the ideal of equal protection by inquiring whether it may fairly be viewed as furthering a *218substantial interest of the State.16 We turn to a consideration of the standard appropriate for the evaluation of §21.031.
A
Sheer incapability or lax enforcement of the laws barring entry into this country, coupled with the failure to establish an effective bar to the employment of undocumented aliens, has resulted in the creation of a substantial “shadow population” of illegal migrants — numbering in the millions —within our borders.17 This situation raises the specter of a perma*219nent caste of undocumented resident aliens, encouraged by some to remain here as a source of cheap labor, but nevertheless denied the benefits that our society makes available to citizens and lawful residents.18 The existence of such an underclass presents most difficult problems for a Nation that prides itself on adherence to principles of equality under law.19
The children who are plaintiffs in these cases are special members of this underclass. Persuasive arguments support the view that a State may withhold its beneficence from those whose very presence within the United States is the product of their own unlawful conduct. These arguments do not ap*220ply with the same force to classifications imposing disabilities on the minor children of such illegal entrants. At the least, those who elect to enter our territory by stealth and in violation of our law should be prepared to bear the consequences, including, but not limited to, deportation. But the children of those illegal entrants are not comparably situated. Their “parents have the ability to conform their conduct to societal norms,” and presumably the ability to remove themselves from the State’s jurisdiction; but the children who are plaintiffs in these cases “can affect neither their parents’ conduct nor their own status.” Trimble v. Gordon, 430 U. S. 762, 770 (1977). Even if the State found it expedient to control the conduct of adults by acting against their children, legislation directing the onus of a parent’s misconduct against his children does not comport with fundamental conceptions of justice.
“[V]isiting. . . condemnation on the head of an infant is illogical and unjust. Moreover, imposing disabilities on the . . . child is contrary to the basic concept of our system that legal burdens should bear some relationship to individual responsibility or wrongdoing. Obviously, no child is responsible for his birth and penalizing the . . . child is an ineffectual — as well as unjust — way of deterring the parent.” Weber v. Aetna Casualty & Surety Co., 406 U. S. 164, 175 (1972) (footnote omitted).
Of course, undocumented status is not irrelevant to any proper legislative goal. Nor is undocumented status an absolutely immutable characteristic since it is the product of conscious, indeed unlawful, action. But §21.031 is directed against children, and imposes its discriminatory burden on the basis of a legal characteristic over which children can have little control. It is thus difficult to conceive of a rational justification for penalizing these children for their presence within the United States. Yet that appears to be precisely the effect of § 21.031.
*221Public education is not a “right” granted to individuals by the Constitution. San Antonio Independent School Dist. v. Rodriguez, 411 U. S. 1, 35 (1973). But neither is it merely some governmental “benefit” indistinguishable from other forms of social welfare legislation. Both the importance of education in maintaining our basic institutions, and the lasting impact of its deprivation on the life of the child, mark the distinction. The “American people have always regarded education and [the] acquisition of knowledge as matters of supreme importance.” Meyer v. Nebraska, 262 U. S. 390, 400 (1923). We have recognized “the public schools as a most vital civic institution for the preservation of a democratic system of government,” Abington School District v. Schempp, 374 U. S. 203, 230 (1963) (Brennan, J., concurring), and as the primary vehicle for transmitting “the values on which our society rests.” Ambach v. Norwich, 441 U. S. 68, 76 (1979). “[A]s . . . pointed out early in our history,. . . some degree of education is necessary to prepare citizens to participate effectively and intelligently in our open political system if we are to preserve freedom and independence.” Wisconsin v. Yoder, 406 U. S. 205, 221 (1972). And these historic “perceptions of the public schools as inculcating fundamental values necessary to the maintenance of a democratic political system have been confirmed by the observations of social scientists.” Ambach v. Norwich, supra, at 77. In addition, education provides the basic tools by which individuals might lead economically productive lives to the benefit of us all. In sum, education has a fundamental role in maintaining the fabric of our society. We cannot ignore the significant social costs borne by our Nation when select groups are denied the means to absorb the values and skills upon which our social order rests.
In addition to the pivotal role of education in sustaining our political and cultural heritage, denial of education to some isolated group of children poses an affront to one of the goals *222of the Equal Protection Clause: the abolition of governmental barriers presenting unreasonable obstacles to advancement on the basis of individual merit. Paradoxically, by depriving the children of any disfavored group of an education, we foreclose the means by which that group might raise the level of esteem in which it is held by the majority. But more directly, “education prepares individuals to be self-reliant and self-sufficient participants in society.” Wisconsin v. Yoder, supra, at 221. Illiteracy is an enduring disability. The inability to read and write will handicap the individual deprived of a basic education each and every day of his life. The inestimable toll of that deprivation on the social, economic, intellectual, and psychological well-being of the individual, and the obstacle it poses to individual achievement, make it most difficult to reconcile the cost or the principle of a status-based denial of basic education with the framework of equality embodied in the Equal Protection Clause.20 What we said 28 years ago in Brown v. Board of Education, 347 U. S. 483 (1954), still holds true:
“Today, education is perhaps the most important function of state and local governments. Compulsory school *223attendance laws and the great expenditures for education both demonstrate our recognition of the importance of education to our democratic society. It is required in the performance of our most basic public responsibilities, even service in the armed forces. It is the very foundation of good citizenship. Today it is a principal instrument in awakening the child to cultural values, in preparing him for later professional training, and in helping him to adjust normally to his environment. In these days, it is doubtful that any child may reasonably be expected to succeed in life if he is denied the opportunity of an education. Such an opportunity, where the state has undertaken to provide it, is a right which must be made available to all on equal terms.” Id., at 493.
B
These well-settled principles allow us to determine the proper level of deference to be afforded §21.031. Undocumented aliens cannot be treated as a suspect class because their presence in this country in violation of federal law is not a “constitutional irrelevancy.” Nor is education a fundamental right; a State need not justify by compelling necessity every variation in the manner in which education is provided to its population. See San Antonio Independent School Dist. v. Rodriguez, supra, at 28-39. But more is involved in these cases than the abstract question whether §21.031 discriminates against a suspect class, or whether education is a fundamental right. Section 21.031 imposes a lifetime hardship on a discrete class of children not accountable for their disabling status. The stigma of illiteracy will mark them for the rest of their lives. By denying these children a basic education, we deny them the ability to live within the structure of our civic institutions, and foreclose any realistic possibility that they will contribute in even the smallest way to the progress of our Nation. In determining *224the rationality of § 21.031, we may appropriately take into account its costs to the Nation and to the innocent children who are its victims. In light of these countervailing costs, the discrimination contained in §21.031 can hardly be considered rational unless it furthers some substantial goal of the State.
t — < C
It is the State’s principal argument, and apparently the view of the dissenting Justices, that the undocumented status of these children vel non establishes a sufficient rational basis for denying them benefits that a State might choose to afford other residents. The State notes that while other aliens are admitted “on an equality of legal privileges with all citizens under non-discriminatory laws,” Takahashi v. Fish & Game Comm’n, 334 U. S. 410, 420 (1948), the asserted right of these children to an education can claim no implicit congressional imprimatur.21 Indeed, in the State’s view, Congress’ apparent disapproval of the presence of these children within the United States, and the evasion of the federal regulatory program that is the mark of undocumented status, provides authority for its decision to impose upon them special disabilities. Faced with an equal protection challenge respecting the treatment of aliens, we agree that the courts must be attentive to congressional policy; the exercise of congressional power might well affect the State’s prerogatives to afford differential treatment to a particular class of aliens. But we are unable to find in the congressional immigration scheme any statement of policy that might weigh signifi*225cantly in arriving at an equal protection balance concerning the State’s authority to deprive these children of an education.
The Constitution grants Congress the power to “establish an uniform Rule of Naturalization.” Art. I., § 8, cl. 4. Drawing upon this power, upon its plenary authority with respect to foreign relations and international commerce, and upon the inherent power of a sovereign to close its borders, Congress has developed a complex scheme governing admission to our Nation and status within our borders. See Mathews v. Diaz, 426 U. S. 67 (1976); Harisiades v. Shaughnessy, 342 U. S. 580, 588-589 (1952). The obvious need for delicate policy judgments has counseled the Judicial Branch to avoid intrusion into this field. Mathews, supra, at 81. But this traditional caution does not persuade us that unusual deference must be shown the classification embodied in §21.031. The States enjoy no power with respect to the classification of aliens. See Hines v. Davidowitz, 312 U. S. 52 (1941). This power is “committed to the political branches of the Federal Government.” Mathews, 426 U. S., at 81. Although it is “a routine and normally legitimate part” of the business of the Federal Government to classify on the basis of alien status, id., at 85, and to “take into account the character of the relationship between the alien and this country,” id., at 80, only rarely are such matters relevant to legislation by a State. See Id., at 84-85; Nyquist v. Mauclet, 432 U. S. 1, 7, n. 8 (1977).
As we recognized in De Canas v. Bica, 424 U. S. 351 (1976), the States do have some authority to act with respect to illegal aliens, at least where such action mirrors federal objectives and furthers a legitimate state goal. In De Canos, the State’s program reflected Congress’ intention to bar from employment all aliens except those possessing a grant of permission to work in this country. Id., at 361. In contrast, there is no indication that the disability imposed by §21.031 corresponds to any identifiable congressional policy. The *226State does not claim that the conservation of state educational resources was ever a congressional concern in restricting immigration. More importantly, the classification reflected in §21.031 does not operate harmoniously within the federal program.
To be sure, like all persons who have entered the United States unlawfully, these children are subject to deportation. 8 U. S. C. §§ 1251, 1252 (1976 ed. and Supp. IV). But there is no assurance that a child subject to deportation will ever be deported. An illegal entrant might be granted federal permission to continue to reside in this country, or even to become a citizen. See, e. g., 8 U. S. C. §§1252, 1253(h), 1254 (1976 ed. and Supp. IV). In light of the discretionary federal power to grant relief from deportation, a State cannot realistically determine that any particular undocumented child will in fact be deported until after deportation proceedings have been completed. It would of course be most difficult for the State to justify a denial of education to a child enjoying an inchoate federal permission to remain.
We are reluctant to impute to Congress the intention to withhold from these children, for so long as they are present in this country through no fault of their own, access to a basic education. In other contexts, undocumented status, coupled with some articulable federal policy, might enhance state authority with respect to the treatment of undocumented aliens. But in the area of special constitutional sensitivity presented by these cases, and in the absence of any contrary indication fairly discernible in the present legislative record, we perceive no national policy that supports the State in denying these children an elementary education. The State may borrow the federal classification. But to justify its use as a criterion for its own discriminatory policy, the State must demonstrate that the classification is reasonably adapted to “the purposes for which the state desires to use it.” Oyama v. California, 332 U. S. 633, 664-665 (1948) (Murphy, J., concurring) (emphasis added). We therefore turn to the state objectives that are said to support § 21.031.
*227V
Appellants argue that the classification at issue furthers an interest in the “preservation of the state’s limited resources for the education of its lawful residents.”22 Brief for Appellants 26. Of course, a concern for the preservation of resources standing alone can hardly justify the classification used in allocating those resources. Graham v. Richardson, 403 U. S. 365, 374-375 (1971). The State must do more than justify its classification with a concise expression of an intention to discriminate. Examining Board v. Flores de Otero, 426 U. S. 572, 605 (1976). Apart from the asserted state prerogative to act against undocumented children solely on the basis of their undocumented status — an asserted prerogative that carries only minimal force in the circumstances of these cases — we discern three colorable state interests that might support §21.031.
*228First, appellants appear to suggest that the State may seek to protect itself from an influx of illegal immigrants. While a State might have an interest in mitigating the potentially harsh economic effects of sudden shifts in population,23 §21.031 hardly offers an effective method of dealing with an urgent demographic or economic problem. There is no evidence in the record suggesting that illegal entrants impose any significant burden on the State’s economy. To the contrary, the available evidence suggests that illegal aliens underutilize public services, while contributing their labor to the local economy and tax money to the state fisc. 458 F. Supp., at 578; 501 F. Supp., at 570-571. The dominant incentive for illegal entry into the State of Texas is the availability of employment; few if any illegal immigrants come to this country, or presumably to the State of Texas, in order to avail themselves of a free education.24 Thus, even making the doubtful assumption that the net impact of illegal aliens on the economy of the State is negative, we think it clear that “[c]harging tuition to undocumented children constitutes a ludicrously ineffectual attempt to stem the tide of illegal immigration,” at least when compared with the alternative of *229prohibiting the employment of illegal aliens. 458 F. Supp., at 585. See 628 F. 2d, at 461; 501 F. Supp., at 579, and n. 88.
Second, while it is apparent that a State may “not... reduce expenditures for education by barring [some arbitrarily chosen class of] children from its schools,” Shapiro v. Thompson, 394 U. S. 618, 633 (1969), appellants suggest that undocumented children are appropriately singled out for exclusion because of the special burdens they impose on the State’s ability to provide high-quality public education. But the record in no way supports the claim that exclusion of undocumented children is likely to improve the overall quality of education in the State.25 As the District Court in No. 80-1934 noted, the State failed to offer any “credible supporting evidence that a proportionately small diminution of the funds spent on each child [which might result from devoting some state funds to the education of the excluded group] will have a grave impact on the quality of education.” 501 F. Supp., at 583. And, after reviewing the State’s school financing mechanism, the District Court in No. 80-1538 concluded that barring undocumented children from local schools would not necessarily improve the quality of education provided in those schools. 458 F. Supp., at 577. Of course, even if improvement in the quality of education were a likely result of barring some number of children from the schools of the State, the State must support its selection of this group as the appropriate target for exclusion. In terms of educational cost and need, however, undocumented children are “basically indistinguishable” from legally resident alien children. Id., at 589; 501 F. Supp., at 583, and n. 104.
Finally, appellants suggest that undocumented children are appropriately singled out because their unlawful presence *230within the United States renders them less likely than other children to remain within the boundaries of the State, and to put their education to productive social or political use within the State. Even assuming that such an interest is legitimate, it is an interest that is most difficult to quantify. The State has no assurance that any child, citizen or not, will employ the education provided by the State within the confines of the State’s borders. In any event, the record is clear that many of the undocumented children disabled by this classification will remain in this country indefinitely, and that some will become lawful residents or citizens of the United States. It is difficult to understand precisely what the State hopes to achieve by promoting the creation and perpetuation of a subclass of illiterates within our boundaries, surely adding to the problems and costs of unemployment, welfare, and crime. It is thus clear that whatever savings might be achieved by denying these children an education, they are wholly insubstantial in light of the costs involved to these children, the State, and the Nation.
VI
If the State is to deny a discrete group of innocent children the free public education that it offers to other children residing within its borders, that denial must be justified by a showing that it furthers some substantial state interest. No such showing was made here. Accordingly, the judgment of the Court of Appeals in each of these cases is
Affirmed.
That section provides, in pertinent part:
“(a) All children who are citizens of the United States or legally admitted aliens and who are over the age of five years and under the age of 21 years on the first day of September of any scholastic year shall be entitled to the benefits of the Available School Fund for that year.
“(b) Every child in this state who is a citizen of the United States or a legally admitted alien and who is over the age of five years and not over the age of 21 years on the first day of September of the year in which admission is sought shall be permitted to attend the public free schools of the district *206in which he resides or in which his parent, guardian, or the person having lawful control of him resides at the time he applies for admission.
“(c) The board of trustees of any public free school district of this state shall admit into the public free schools of the district free of tuition all persons who are either citizens of the United States or legally admitted aliens and who are over five and not over 21 years of age at the beginning of the scholastic year if such person or his parent, guardian or person having lawful control resides within the school district.”
2 Despite the enactment of § 21.031 in 1975, the School District had continued to enroll undocumented children free of charge until the 1977-1978 school year. In July 1977, it adopted a policy requiring undocumented children to pay a “full tuition fee” in order to enroll. Section 21.031 had not provided a definition of “a legally admitted alien.” Tyler offered the following clarification:
“A legally admitted alien is one who has documentation that he or she is legally in the United States, or a person who is in the process of securing documentation from the United States Immigration Service, and the Service will state that the person is being processed and will be admitted with proper documentation.” App. to Juris. Statement in No. 80-1538, p. A-38.
The court contrasted this group with those illegal aliens who entered the country alone in order to earn money to send to their dependents in Mexico, and who in many instances remained in this country for only a short period of time. 458 F. Supp., at 578.
Plaintiffs’ expert, Dr. Gilbert Cardenas, testified that “fifty to sixty per cent... of current legal alien workers were formerly illegal aliens.” Id., at 577. A defense witness, Rolan Heston, District Director of the Hous*208ton District of the Immigration and Naturalization Service, testified that “undocumented children can and do live in the United States for years, and adjust their status through marriage to a citizen or permanent resident.” Ibid. The court also took notice of congressional proposals to “legalize” the status of many unlawful entrants. Id., at 577-578. See also n. 17, infra.
The court found § 21.031 inconsistent with the scheme of national regulation under the Immigration and Nationality Act, and with federal laws pertaining to funding and discrimination in education. The court distinguished De Canas v. Bica, 424 U. S. 351 (1976), by emphasizing that the state bar on employment of illegal aliens involved in that case mirrored precisely the federal policy, of protecting the domestic labor market, underlying the immigration laws. The court discerned no express federal policy to bar illegal immigrants from education. 458 F. Supp., at 590-592.
The Court of Appeals noted that De Canas v. Bica, supra, had not foreclosed all state regulation with respect to illegal aliens, and found no express or implied congressional policy favoring the education of illegal aliens. The court therefore concluded that there was no pre-emptive conflict between state and federal law. 628 F. 2d, at 451-454.
The court concluded that §21.031 was not pre-empted by federal laws or international agreements. 501 F. Supp., at 584-596.
Appellees in both cases continue to press the argument that § 21.031 is pre-empted by federal law and policy. In light of our disposition of the Fourteenth Amendment issue, we have no occasion to reach this claim.
It would be incongruous to hold that the United States, to which the Constitution assigns a broad authority over both naturalization and foreign affairs, is barred from invidious discrimination with respect to unlawful *211aliens, while exempting the States from a similar limitation. See 426 U. S., at 84-86.
Although we have not previously focused on the intended meaning of this phrase, we have had occasion to examine the first sentence of the Fourteenth Amendment, which provides that “[a]ll persons bom or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States . . . .” (Emphasis added.) Justice Gray, writing for the Court in United States v. Wong Kim Ark, 169 U. S. 649 (1898), detailed at some length the history of the Citizenship Clause, and the predominantly geographic sense in which the term “jurisdiction” was used. He further noted that it was “impossible to construe the words ‘subject to the jurisdiction thereof,’ in the opening sentence [of the Fourteenth Amendment], as less comprehensive than the words ‘within its jurisdiction,’ in the concluding sentence of the same section; or to hold that persons ‘within the jurisdiction’ of one of the States of the Union are not ‘subject to the jurisdiction of the United States.’ ” Id., at 687.
Justice Gray concluded that “[ejvery citizen or subject of another country, while domiciled here, is within the allegiance and the protection, and consequently subject to the jurisdiction, of the United States.” Id., at 693. As one early commentator noted, given the historical emphasis on geographic territoriality, bounded only, if at all, by principles of sovereignty and allegiance, no plausible distinction with respect to Fourteenth Amendment “jurisdiction” can be drawn between resident aliens whose entry into the United States was lawful, and resident aliens whose entry was unlawful. See C. Bouvé, Exclusion and Expulsion of Aliens in the United States 426-427 (1912).
In his separate opinion, Justice Field addressed the relationship between the Fifth and Fourteenth Amendments:
“The term ‘person,’ used in the Fifth Amendment, is broad enough to include any and every human being within the jurisdiction of the republic. A resident, alien born, is entitled to the same protection under the laws that a citizen is entitled to. He owes obedience to the laws of the country in which he is domiciled, and, as a consequence, he is entitled to the equal protection of those laws. . . . The contention that persons within the territorial jurisdiction of this republic might be beyond the protection of the law was heard with pain on the argument at the bar — in face of the great constitutional amendment which declares that no State shall deny to any person within its jurisdiction the equal protection of the laws.” Wong Wing v. United States, 163 U. S., at 242-243 (concurring in part and dissenting in part).
Leng May Ma v. Barber, 357 U. S. 185 (1958), relied on by appellants, is not to the contrary. In that case the Court held, as a matter of status *213tory construction, that an alien paroled into the United States pursuant to § 212(d)(5) of the Immigration and Nationality Act, 8 U. S. C. § 1182(d)(5) (1952 ed.), was not “within the United States” for the purpose of availing herself of § 243(h), which authorized the withholding of deportation in certain circumstances. The conclusion reflected the longstanding distinction between exclusion proceedings, involving the determination of admissibility, and deportation proceedings. The undocumented children who are ap-pellees here, Unlike the parolee in Leng May Ma, supra, could apparently be removed from the country only pursuant to deportation proceedings. 8 U. S. C. § 1251(a)(2). See 1A C. Gordon & H. Rosenfield, Immigration Law and Procedure §3.16b, p. 3-161 (1981).
Representative Bingham’s views are also reflected in his comments on the Civil Rights Bill of 1866. He repeatedly referred to the need to provide protection, not only to the freedmen, but to “the alien and stranger,” and to “refugees . . . and all men.” Cong. Globe, 39th Cong., 1st Sess., 1292 (1866).
Several formulations might explain our treatment of certain classifications as “suspect.” Some classifications are more likely than others to reflect deep-seated prejudice rather than legislative rationality in pursuit of some legitimate objective. Legislation predicated on such prejudice is easily recognized as incompatible with the constitutional understanding that each person is to be judged individually and is entitled to equal justice *217under the law. Classifications treated as suspect tend to be irrelevant to any proper legislative goal. See McLaughlin v. Florida, 379 U. S. 184, 192 (1964); Hirabayashi v. United States, 320 U. S. 81, 100 (1943). Finally, certain groups, indeed largely the same groups, have historically been “relegated to such a position of political powerlessness as to command extraordinary protection from the majoritarian political process.” San Antonio Independent School Dist. v. Rodriguez, 411 U. S. 1, 28 (1973); Graham v. Richardson, 403 U. S. 365, 372 (1971); see United States v. Carolene Products Co., 304 U. S. 144, 152-153, n. 4 (1938). The experience of our Nation has shown that prejudice may manifest itself in the treatment of some groups. Our response to that experience is reflected in the Equal Protection Clause of the Fourteenth Amendment. Legislation imposing special disabilities upon groups disfavored by virtue of circumstances beyond their control suggests the kind of “class or caste” treatment that the Fourteenth Amendment was designed to abolish.
In determining whether a class-based denial of a particular right is deserving of strict scrutiny under the Equal Protection Clause, we look to the Constitution to see if the right infringed has its source, explicitly or implicitly, therein. But we have also recognized the fundamentally of participation in state “elections on an equal basis with other citizens in the jurisdiction,” Dunn v. Blumstein, 405 U. S. 330, 336 (1972), even though “the right to vote, per se, is not a constitutionally protected right." San Antonio Independent School Dist., supra, at 35, n. 78. With respect to suffrage, we have explained the need for strict scrutiny as arising from the significance of the franchise as the guardian of all other rights. See Harper v. Virginia Bd. of Elections, 383 U. S. 663, 667 (1966); Reynolds v. Sims, 377 U. S. 533, 562 (1964); Yick Wo v. Hopkins, 118 U. S. 356, 370 (1886).
See Craig v. Boren, 429 U. S. 190 (1976); Lalli v. Lalli, 439 U. S. 259 (1978). This technique of “intermediate” scrutiny permits us to evaluate the rationality of the legislative judgment with reference to well-settled constitutional principles. “In expounding the Constitution, the Court’s role is to discern ‘principles sufficiently absolute to give them roots throughout the community and continuity over significant periods of time, and to lift them above the level of the pragmatic political judgments of a particular time and place.’ ” University of California Regents v. Bakke, 438 U. S. 265, 299 (1978) (opinion of POWELL, J.), quoting A. Cox, The Role of the Supreme Court in American Government 114 (1976). Only when concerns sufficiently absolute and enduring can be clearly ascertained from the Constitution and our cases do we employ this standard to aid us in determining the rationality of the legislative choice.
The Attorney General recently estimated the number of illegal aliens within the United States at between 3 and 6 million. In presenting to both the Senate and House of Representatives several Presidential proposals for reform of the immigration laws — including one to “legalize” many of the illegal entrants currently residing in the United States by creating for them a special status under the immigration laws — the Attorney General noted that this subclass is largely composed of persons with a permanent attachment to the Nation, and that they are unlikely to be displaced from our territory:
“We have neither the resources, the capability, nor the motivation to uproot and deport millions of illegal aliens, many of whom have become, in effect, members of the community. By granting limited legal status to the productive and law-abiding members of this shadow population, we will recognize reality and devote our enforcement resources to deterring future illegal arrivals.” Joint Hearing before the Subcommittee on Immigration, Refugees, and International Law of the House Committee on the Judiciary *219and the Subcommittee on Immigration and Refugee Policy of the Senate Committee on the Judiciary, 97th Cong., 1st Sess., 9 (1981) (testimony of William French Smith, Attorney General).
As the District Court observed in No. 80-1538, the confluence of Government policies has resulted in “the existence of a large number of employed illegal aliens, such as the parents of plaintiffs in this case, whose presence is tolerated, whose employment is perhaps even welcomed, but who are virtually defenseless against any abuse, exploitation, or callous neglect to which the state or the state’s natural citizens and business organizations may wish to subject them.” 458 F. Supp., at 585.
We reject the claim that “illegal aliens” are a “suspect class.” No case in which we have attempted to define a suspect class, see, e. g., n. 14, supra, has addressed the status of persons unlawfully in our country. Unlike most of the classifications that we have recognized as suspect, entry into this class, by virtue of entry into this country, is the product of voluntary action. Indeed, entry into the class is itself a crime. In addition, it could hardly be suggested that undocumented status is a “constitutional irrelevancy.” With respect to the actions of the Federal Government, alien-age classifications may be intimately related to the conduct of foreign policy, to the federal prerogative to control access to the United States, and to the plenary federal power to determine who has sufficiently manifested his allegiance to become a citizen of the Nation. No State may independently exercise a like power. But if the Federal Government has by uniform rule prescribed what it believes to be appropriate standards for the treatment of an alien subclass, the States may, of course, follow the federal direction. See De Canas v. Bica, 424 U. S. 351 (1976).
Because the State does not afford noncitizens the right to vote, and may bar noncitizens from participating in activities at the heart of its political community, appellants argue that denial of a basic education to these children is of less significance than the denial to some other group. Whatever the current status of these children, the courts below concluded that many will remain here permanently and that some indeterminate number will eventually become citizens. The fact that many will not is not decisive, even with respect to the importance of education to participation in core political institutions. “[T]he benefits of education are not reserved to those whose productive utilization of them is a certainty . . . .” 458 F. Supp., at 581, n. 14. In addition, although a noncitizen “may be barred from full involvement in the political arena, he may play a role — perhaps even a leadership role — in other areas of import to the community.” Nyquist v. Mauclet, 432 U. S. 1, 12 (1977). Moreover, the significance of education to our society is not limited to its political and cultural fruits. The public schools are an important socializing institution, imparting those shared values thróugh which social order and stability are maintained.
If the constitutional guarantee of equal protection was available only to those upon whom Congress affirmatively granted its benefit, the State’s argument would be virtually unanswerable. But the Equal Protection Clause operates of its own force to protect anyone “within [the State’s] jurisdiction” from the State’s arbitrary action. See Part II, supra. The question we examine in text is whether the federal disapproval of the presence of these children assists the State in overcoming the presumption that denial of education to innocent children is not a rational response to legitimate state concerns.
Appellant School District sought at oral argument to characterize the alienage classification contained in §21.031 as simply a test of residence. We are unable to uphold § 21.031 on that basis. Appellants conceded that if, for example, a Virginian or a legally admitted Mexican citizen entered Tyler with his school-age children, intending to remain only six months, those children would be viewed as residents entitled to attend Tyler schools. Tr. of Oral Arg. 31-32. It is thus clear that Tyler’s residence argument amounts to nothing more than the assertion that illegal entry, without more, prevents a person from becoming a resident for purposes of enrolling his children in the public schools. A State may not, however, accomplish what would otherwise be prohibited by the Equál Protection Clause, merely by defining a disfavored group as nonresident. And illegal entry into the country would not, under traditional criteria, bar a person from obtaining domicile within a State. C. Bouvé, Exclusion and Expulsion of Aliens in the United States 340 (1912). Appellants have not shown that the families of undocumented children do not comply with the established standards by which the State historically tests residence. Apart from the alienage limitation, § 21.031(b) requires a school district to provide education only to resident children. The school districts of the State are as free to apply to undocumented children established criteria for determining residence as they are to apply those criteria to any other child who seeks admission.
Although the State has no direct interest in controlling entry into this country, that interest being one reserved by the Constitution to the Federal Government, unchecked unlawful migration might impair the State’s economy generally, or the State’s ability to provide some important service. Despite the exclusive federal control of this Nation’s borders, we cannot conclude that the States are without any power to deter the influx of persons entering the United States against federal law, and whose numbers might have a discernible impact on traditional state concerns. See De Canas v. Bica, 424 U. S., at 354-356.
The courts below noted the ineffectiveness of the Texas provision as a means of controlling the influx of illegal entrants into the State. See 628 F. 2d, at 460-461; 458 F. Supp., at 585; 501 F. Supp., at 578 (“The evidence demonstrates that undocumented persons do not immigrate in search for a free public education. Virtually all of the undocumented persons who come into this country seek employment opportunities and not educational benefits. . . . There was overwhelming evidence ... of the unimportance of public education as a stimulus for immigration”) (footnote omitted).
Nor does the record support the claim that the educational resources of the State are so direly limited that some form of “educational triage” might be deemed a reasonable (assuming that it were a permissible) response to the State’s problems. Id., at 579-581.
I use the term “citizen” advisedly. The right to vote, of course, is a political interest of concern to citizens. The right to an education, in contrast, is a social benefit of relevance to a substantial number of those affected by Texas’ statutory scheme, as is discussed below.
