OPINION OF THE COURT
I. INTRODUCTION
The question of law to be answered is whether KRS 17.545, which restricts where registered sex offenders may live, may be applied to those who committed their offenses prior to July 12, 2006, the effective date of the statute. We hold that it may not. Even though the General Assembly did not intend the statute to be punitive, the residency restrictions are so punitive in effect as to negate any intention to deem them civil. Therefore, the retroactive application of KRS 17.545 is an ex post facto punishment, which violates Article I, Section 10 of the United States Constitution, and Section 19(1) of the Kentucky Constitution.
II. BACKGROUND
A. Kentucky’s Sex Offender Residency Restrictions
On July 29, 1994, seven-year-old Megan Kanka disappeared from her neighborhood in Hamilton Township, New Jersey. Soon *440after, police discovered that Megan had been raped and murdered by a man previously convicted of sex offenses. New Jersey enacted what became known as “Megan’s Law,” requiring sex offenders to register with the state, and establishing notification procedures for those living nearby. The same year, Congress passed the Jacob Wetterling Crimes Against Children and Sexually Violent Offenders Registration Act, which conditioned certain law enforcement funding on states enacting their own version of Megan’s Law.
Like every other state, Kentucky has enacted a version of Megan’s Law. The General Assembly first enacted sex offender registration requirements in 1994, amending them in 1996 and again in 2000. The 2000 amendments to our Megan’s Law also included residency restrictions on sex offenders as a condition of their probation or parole. That restriction, codified at KRS 17.495, read as follows:
No registrant, as defined in KRS 17.500, who is placed on probation, parole, or other form of supervised release, shall reside within one thousand (1,000) feet of a high school, middle school, elementary school, preschool, or licensed day care facility. The measurement shall be taken in a straight line from the nearest wall of the school to the nearest wall of the registrant’s place of residence.
This Court upheld the registration provisions of Kentucky’s Megan’s Law in Hyatt v. Commonwealth, 72 S.W.3d 566 (Ky.2002). The next year, the United States Supreme Court upheld Alaska’s sex offender registration statute against an ex post facto challenge in Smith v. Doe, 538 U.S. 84, 123 S.Ct. 1140, 155 L.Ed.2d 164 (2003).1
In 2006, the General Assembly enacted House Bill 3, which amended Kentucky’s residency restrictions to their current form. 2006 Ky. Acts 182. The current residency restriction statute, effective July 12, 2006, codified at KRS 17.545, reads as follows:
(1) No registrant, as defined in KRS 17.500, shall reside within one thousand (1,000) feet of a high school, middle school, elementary school, preschool, publicly owned playground, or licensed day care facility. The measurement shall be taken in a straight line from the nearest property line of the school to the nearest property line of the registrant’s place of residence.
(2) For purposes of this section:
(a) The registrant shall have the duty to ascertain whether any property listed in subsection (1) of this section is within one thousand (1,000) feet of the registrant’s residence; and
(b) If a new facility opens, the registrant shall be presumed to know and, within ninety (90) days, shall comply with this section.
(3) Any person who violates subsection (1) of this section shall be guilty of:
(a) A Class A misdemeanor for a first offense; and
(b) A Class D felony for the second and each subsequent offense.
(4) Any registrant residing within one thousand (1,000) feet of a high school, middle school, elementary school, preschool, publicly owned playground, or licensed day care facility on July 12, 2006, shall move and comply with this section within ninety (90) days of July 12, 2006, and *441thereafter, shall be subject to the penalties set forth under subsection (3) of this section.
(5) This section shall not apply to a youthful offender probated or paroled during his or her minority or while enrolled in an elementary or secondary education program.
While the original residency restriction statute applied only to those on probation, parole, or other form of supervised release, the current statute applies to all registrants regardless of probation or parole status. In addition, KRS 17.545 adds publicly owned playgrounds to the list of prohibited areas, and measures the distance from the property line as opposed to the wall of a building. The statute also places the burden on the registrant to determine whether he is in compliance. Violation of the residency restriction is a Class A misdemeanor for the first offense, and a Class D felony for subsequent offenses.
B. Procedural History
On March 31, 1995, Respondent Michael Baker entered a guilty plea to a charge of third-degree rape in Kenton Circuit Court. In addition to Respondent’s probated sentence of five years imprisonment, pursuant to the version of KRS 17.520 in effect at the time, Respondent was required to register as a sex offender until March 27, 2010.
Respondent subsequently lived in Reading, Ohio with his family. However, the City of Reading’s sex offender residency restrictions forced Respondent to move back to Kentucky. On February 2, 2007, Respondent resided in Elsmere, Kentucky and was arrested and charged with violating KRS 17.545 for living within 1,000 feet of East Covered Bridge Park, allegedly a public playground.
According to Respondent, the Division of Probation and Parole provided him with a link to a website to determine whether he was in compliance with KRS 17.545. The website did not show East Covered Bridge Park and the surrounding area to be a prohibited zone.
In Kenton District Court, Respondent challenged KRS 17.545 on a number of constitutional grounds and moved to dismiss the charges against him. On April 20, 2007. the Kenton District Court granted Respondent’s motion and dismissed the charges.
The district court concluded that KRS 17.545, as applied to Respondent, violated the ex post facto clauses of the United States and Kentucky Constitutions. In its thorough opinion, the district court found that the General Assembly had intended KRS 17.545 to be punitive. The district court also found that, even if KRS 17.545 were not clearly punitive, its effect was punitive. Upon finding the statute to be unconstitutional as applied to Respondent, the district court declined to address the remaining constitutional challenges.
The Commonwealth then moved this Court for certification of law to determine whether KRS 17.545 is an ex post facto punishment. See Ky. Const. § 115, CR 76.37(10). We granted certification to resolve this important constitutional issue.2
*442III. ANALYSIS
The United States Constitution and the Kentucky Constitution, through their respective ex post facto clauses,3 prohibit the enactment of any law that imposes or increases the punishment for criminal acts committed prior to the law’s enactment. The Ex Post Facto Clause of the United States Constitution “forbids ... the States to enact any law ‘which imposes a punishment for an act which was not punishable at the time it was committed; or imposes additional punishment to that then prescribed.’ ” Weaver v. Graham, 450 U.S. 24, 28, 101 S.Ct. 960, 67 L.Ed.2d 17 (1981) (quoting Cummings v. Missouri, 71 U.S. (4 Wall.) 277, 325-26, 18 L.Ed. 356 (1866)).
As a threshold question, for a law to be considered ex post facto, “it must be retrospective, that is, it must apply to events occurring before its enactment, and it must disadvantage the offender affected by it.” Hyatt, 72 S.W.3d at 571 (quoting Weaver, 450 U.S. at 29, 101 S.Ct. 960). There is no question that KRS 17.545 applies to conduct by Respondent that occurred well before the law’s enactment. In addition, Respondent is disadvantaged by the law, as it restricts where he may live. However, to violate the ex post facto clause, the statute must also be punitive. Martin v. Chandler, 122 S.W.3d 540, 547 (Ky.2003) (citing California Dept. of Corr. v. Morales, 514 U.S. 499, 506 n. 3, 115 S.Ct. 1597, 131 L.Ed.2d 588 (1995)).
In determining whether, with regard to those like Respondent, KRS 17.545 constitutes retroactive punishment forbidden by the ex post facto clauses, we are guided by the United States Supreme Court’s two-part test from Smith v. Doe, 538 U.S. 84, 123 S.Ct. 1140, 155 L.Ed.2d 164 (2003). First, we must determine whether the legislature intended to establish a civil, nonpunitive, regulatory scheme, or whether the legislature intended to impose punishment. Id. at 92, 123 S.Ct. 1140 (citing Kansas v. Hendricks, 521 U.S. 346, 361, 117 S.Ct. 2072, 138 L.Ed.2d 501 (1997)). If the legislature intended to impose punishment, our inquiry ends. Smith, 538 U.S. at 92, 123 S.Ct. 1140. If, however, the legislature intended to enact a civil, nonpunitive, regulatory scheme, then we must determine “whether the statutory scheme is so punitive either in purpose or effect as to negate the State’s intention to deem it ‘civil.’ ” Id. (quoting Hendricks, 521 U.S. at 361, 117 S.Ct. 2072) (internal quotations and citations omitted).
A. Whether the General Assembly Intended KRS 17.545 to be Punitive
We must first determine whether the General Assembly intended to establish a civil, nonpunitive, regulatory scheme, or whether the legislature intended to impose punishment. In determining the legislature’s intent, this Court “must first ask whether the legislature, in establishing the penalizing mechanism, indicated either expressly or impliedly a preference for one label or the other.” Smith, 538 U.S. at 93, 123 S.Ct. 1140 (quoting Hudson v. United *443States, 522 U.S. 93, 99, 118 S.Ct. 488, 139 L.Ed.2d 450 (1997)). Therefore, we look to the General Assembly’s expressed and implied intent. In determining the General Assembly’s implied intent, we look to, as discussed in Smith, “[ojther formal attributes of a legislative enactment, such as the manner of its codification or the enforcement procedures it establishes.” 538 U.S. at 94, 123 S.Ct. 1140.
We begin by examining the General Assembly’s expressed intent in enacting KRS 17.545. The legislative history of House Bill 3 is extremely sparse. The bill was entitled “AN ACT related to sex offenses and the punishment thereof.” 2006 Ky. Acts 182. This title suggests that the General Assembly intended KRS 17.545 to be punitive. However, while the title of an act may be used as an aid in statutory construction, Wheeler & Clevenger Oil Co., Inc. v. Washburn, 127 S.W.3d 609, 613 (Ky.2004), we do not believe that it should be determinative in this situation.
We therefore look to the General Assembly’s implied intent in enacting KRS 17.545. First, we consider the manner of its codification. Kentucky’s original sex offender residency restrictions, which were codified at KRS 17.495, were part of the 2000 amendments to Kentucky’s Megan’s Law.4 2000 Ky. Acts 401. In Hyatt v. Commonwealth, this Court, addressing the sex offender registration portions of our Megan’s Law (including the 2000 amendments), concluded that those statutes “are directly related to the nonpunitive goals of protecting the safety of the public.” 72 S.W.3d at 572.
Second, we look at the penalties established by KRS 17.545. Violation of residency restrictions is a crime: a Class A misdemeanor for the first offense and a class D felony for subsequent offenses. KRS 17.545(3). However, criminal liability attaches only if the offender fails to move. This is similar to the criminal liability under KRS 17.510(11) for failing to register as a sex offender, which we upheld in Hyatt, 72 S.W.3d at 573. See also Smith, 538 U.S. at 101-02, 123 S.Ct. 1140 (“A sex offender who fails to comply with the reporting requirement may be subjected to a criminal prosecution for that failure, but any prosecution is a proceeding separate from the individual’s original offense.”).
We conclude that the General Assembly intended KRS 17.545 to be a civil, nonpuni-tive, regulatory scheme. Therefore, we now consider the second part of the Smith test.
B. Whether KRS 17.545 is Punitive in Purpose or Effect
Because we conclude that the General Assembly did not intend KRS 17.545 to be punitive, we must now determine “whether the statutory scheme is so punitive either in purpose or effect as to negate the State’s intention to deem it ‘civil.’ ” Smith, 538 U.S. at 92, 123 S.Ct. 1140 (quoting Hendricks, 521 U.S. at 361, 117 S.Ct. 2072) (internal quotations and citations omitted). In making such a determination, courts are guided by seven factors originally discussed in Kennedy v. Mendoza-Martinez, 372 U.S. 144, 168-69, 83 S.Ct. 554, 9 L.Ed.2d 644 (1963). Smith, 538 U.S. at 97, 123 S.Ct. 1140.
As in Smith, the five factors relevant here are, “whether, in its necessary operation, the regulatory scheme” (1) has been regarded in our history and traditions as punishment, (2) promotes the traditional aims of punishment, (3) imposes an affirmative disability or restraint, (4) has a rational connection to a nonpunitive pur*444pose, or (5) is excessive with respect to the nonpunitive purpose. Id.
1. Historically Regarded as Punishment
We first address whether the scheme established by KRS 17.545 has been regarded in our history and traditions as punishment. Traditionally, the colonial era practice of banishing an offender from the community has been regarded as a form of punishment. Smith, 538 U.S. at 98, 123 S.Ct. 1140. Banishment has been defined as “punishment inflicted upon criminals by compelling them to quit a city, place, or country, for a specified period of time, or for life.” United States v. Ju Toy, 198 U.S. 253, 269-70, 25 S.Ct. 644, 49 L.Ed. 1040 (1905).
As the district court noted, courts reviewing sex offender residency restrictions have avoided or sidestepped the issue of whether these restrictions constitute banishment, and “dissenting judges have been far more intellectually honest concluding that residency restrictions constitute banishment.” While KRS 17.545 is not identical to traditional banishment,5 it does prevent the registrant from residing in large areas of the community. It also expels registrants from their own homes, even if their residency predated the statute or arrival of the school, daycare, or playground. Such restrictions strike this Court as decidedly similar to banishment. We therefore conclude that the residency restrictions in KRS 17.545 have been regarded in our history and traditions as punishment.
2. Promotion of the Traditional Aims of Punishment
Next, we address whether KRS 17.545 promotes the traditional aims of punishment: retribution and deterrence. Mendoza-Martinez, 372 U.S. at 168, 83 S.Ct. 554. KRS 17.545 promotes general deterrence through the threat of negative consequences, i.e. eviction or restriction of where a person may live in the future. More significant, however, is the statute’s retributive effect.
KRS 17.545 makes no individualized determination of the dangerousness of a particular registrant. Even those registrants whose victims were adults are prohibited from living near an area where children gather. When a restriction is imposed equally upon all offenders, with no consideration given to how dangerous any particular registrant may be to public safety, that restriction begins to look far more like retribution for past offenses than a regulation intended to prevent future ones. In his concurring opinion in Smith, Justice Souter expressed his unease with the absence of individualized risk assessment:
Ensuring public safety is, of course, a fundamental regulatory goal ... and this objective should be given serious weight in the analyses. But, at the same time, it would be naive to look no further, given pervasive attitudes toward sex offenders.... The fact that the Act uses past crime as the touchstone, probably sweeping in a significant number of people who pose no real threat to the community, serves to feed suspicion that something more than regulation of safety is going on; when a legislature uses prior convictions to impose burdens that outpace the law’s stated civil aims, there is room for serious argument that the ulterior purpose is to revisit past crimes, not prevent future ones.
*445Smith, 538 U.S. at 108-09, 123 S.Ct. 1140 (Souter, J., concurring). By imposing restraints based solely upon prior offenses, KRS 17.545 promotes and furthers retribution against sex offenders for their past crimes. We therefore conclude that KRS 17.545 promotes the traditional aims of punishment.
3. Affirmative Disability or Restraint
Next, we address whether KRS 17.545 imposes an affirmative disability or restraint. We find it difficult to imagine that being prohibited from residing within certain areas does not qualify as an affirmative disability or restraint. In Hyatt, this Court upheld registration requirements, noting that registration does “not place limitations on the activities of the offender.... ” 72 S.W.3d at 572 (citing Collie v. State, 710 So.2d 1000 (Fla.Ct.App.1998)). In Smith, the U.S. Supreme Court found it significant that “offenders subject to the Alaska [registration] statute are free to move where they wish and to live and work as other citizens, with no supervision.” 538 U.S. at 101, 123 S.Ct. 1140.
By contrast, KRS 17.545 places significant limitations on where a registrant may five. With this limitation come significant collateral consequences. As the district court noted, the restrictions could, for example, “impact where an offender’s children attend school, access to public transportation for employment purposes, access to employment opportunities, access to drug and alcohol rehabilitation programs and even access to medical care and residential nursing home facilities for the aging offender.”
The registrant also faces a constant threat of eviction “because there is no way for him or her to find a permanent home in that there are no guarantees a school or [other facility] ... will not open within 1,000 feet of any given location.” State v. Pollard, 908 N.E.2d 1145 at 1150 (Ind.2009). As such, a registrant cannot establish a permanent home. KRS 17.545 clearly imposes affirmative disabilities and restraints upon registrants.
4. Rational Connection to a Nonpuni-tive Purpose
We next consider whether KRS 17.545 has a rational connection to a legitimate nonpunitive public purpose. The Commonwealth argues that residency restrictions serve the nonpunitive purpose of public safety, which is undoubtedly a legitimate purpose. The question is therefore whether KRS 17.545 bears a rational connection to public safety.
KRS 17.545 prohibits registrants from residing (i.e. sleeping at night, when children are not present) within 1,000 feet of areas where children congregate, but it does not prohibit registrants from spending all day at a school, daycare center, or playground (when children are present). It allows registered sex offenders to sit across the street and watch children, and even to work near children. KRS 17.545 does not even restrict an offender from living with the victim, so long as they live and sleep outside of the prohibited area. All KRS 17.545 prohibits is residing in a home within the prohibited zone. It does not regulate contact with children. It is difficult to see how public safety is enhanced by a registrant not being allowed to sleep near a school at night, when children are not present, but being allowed to stay there during the day, when children are present.6
KRS 17.545 is connected to public safety. However, the statute’s inherent flaws *446prevent that connection from being “rational.” Therefore, we conclude that KRS 17.545does not have a rational connection to a nonpunitive purpose.
5. Excessive with Respect to a Non-punitive Purpose
Finally, we address whether KRS 17.545 is excessive with respect to the nonpunitive purpose of public safety. In making that determination, we note the lack of individualized risk assessment, combined with the statute’s fluidity.
First, as noted previously, KRS 17.545 does not make any type of individualized assessment as to whether a particular offender is a threat to public safety. KRS 17.545prohibits all registrants — regardless of whether the registrant’s victim was an adult, teenager, or child, and regardless of whether the crime was violent, nonviolent, or statutory — from living within 1,000 feet of a school, playground, or daycare facility. There is absolutely no individual determination.
The Commonwealth correctly points out that a “statute .is not deemed punitive simply because it lacks a close or perfect fit with the nonpunitive aims it seeks to advance.” Smith, 538 U.S. at 103, 123 S.Ct. 1140. In Smith, the U.S. Supreme Court concluded that individual assessment was not necessary for sex offender registration requirements, and that “[t]he State’s determination to legislate with respect to convicted sex offenders as a class, rather than require individual determination of their dangerousness, does not make the statute a punishment under the Ex Post Facto Clause.” Id. at 104, 123 S.Ct. 1140.
In Kansas v. Hendricks, the U.S. Supreme Court upheld involuntary civil commitment of sex offenders who had completed their period of incarceration. 521 U.S. 346, 117 S.Ct. 2072, 138 L.Ed.2d 501. The Kansas law at issue required individual assessment of offenders prior to commitment. Id. at 352-53, 117 S.Ct. 2072. The Smith court noted that, while individual assessment is not required for sex offender registration, in Hendricks, “[t]he magnitude of the restraint made individual assessment appropriate.” Smith, 538 U.S. at 104, 123 S.Ct. 1140.
The residency restrictions found in KRS 17.545are more onerous than the registration requirements at issue in Hyatt and Smith, but less onerous than the involuntary commitment in Hendricks. We believe that the “magnitude of the restraint” involved in residency restrictions is sufficient for a lack of individual assessment to render the statute punitive.
The record before us does not reveal whether or not Respondent might be a threat to children and to public safety. But this is exactly why KRS 17.545 is excessive.7 Given the drastic consequences of Kentucky’s residency restrictions, and the fact that there is no individual determination of the threat a particular registrant poses to public safety, we can only conclude that KRS 17.545 is excessive with respect to the nonpunitive purpose of public safety.
Second, as the district court stated, “[t]he excessiveness of Kentucky’s residency restrictions is further heightened by their fluidity.” While a sex offender may be permitted one day to live in a particular home, he may the next day find himself prohibited by the opening of a school, day*447care facility, or playground. Perhaps even more troublesome is the fact that a city could easily designate an area a playground, and the statute provides no guidance as to what exactly qualifies as a “playground.”
While such fluidity may provide little problem for registrants in rural areas of Kentucky, it should be easy to see why this becomes a serious burden in areas such as Louisville, Lexington, or Respondent’s home of Northern Kentucky, with its dozens of tightly clustered municipalities. Furthermore, the statute places the sole burden on the registrant in determining whether or not he is in compliance. KRS 17.545(2). This fluidity and uncertainty makes KRS 17.545 excessive with respect to the purpose of public safety.
Of the five Smith factors, all five weigh in favor of concluding that KRS 17.545 is punitive in effect. Therefore, we conclude that KRS 17.545 is so punitive in effect as to negate the General Assembly’s intention to deem it civil.
IV. CONCLUSION
Although the General Assembly did not intend KRS 17.545 to be punitive, the residency restrictions are so punitive in effect as to negate any intention to deem them civil. Therefore, the statute may not constitutionally be applied to those like Respondent, who committed their crimes pri- or to July 12, 2006, the effective date of the statute. To do so violates the ex post facto clauses of the United States and Kentucky constitutions. The law is so certified.
CUNNINGHAM, NOBLE, SCHRODER, SCOTT, and VENTERS, JJ., concur. ABRAMSON, J., dissents by separate opinion in which MINTON, C.J., joins.. Doe subsequently challenged the registration statute in state court on state law grounds, with the Alaska Supreme Court holding that the statute cannot be applied retroactively. Doe v. State, 189 P.3d 999 (Alaska 2008).
. The Indiana Supreme Court recently held that, as applied to those who committed their crimes before the statute was enacted, Indiana's sex offender residency restriction statute constitutes retroactive punishment forbidden by the ex post facto clause of the state's constitution. State v. Pollard, 908 N.E.2d 1145 (Ind.2009).
See also Mikaloff v. Walsh, No. 5:06-CV-96, 2007 WL 2572268 (N.D.Ohio Sept.4, 2007) (holding that retroactive application of Ohio's residency restriction statute violates the federal Ex Post Facto Clause). The Mikaloff ap*442peal was dismissed at the State’s request, presumably because the Ohio Supreme Court subsequently prohibited retroactive application of the residency restriction statute on grounds that the Ohio legislature had not expressly made the law retroactive. See Hyle v. Porter, 117 Ohio St.3d 165, 882 N.E.2d 899 (2008).
But see, e.g., Doe v. Miller, 405 F.3d 700 (8th Cir.2005); State v. Seering, 701 N.W.2d 655 (Iowa 2005); Thompson v. State, 278 Ga. 394, 603 S.E.2d 233 (2004); People v. Leroy, 357 Ill.App.3d 530, 293 Ill.Dec. 459, 828 N.E.2d 769 (2005); Lee v. State, 895 So.2d 1038 (Ala.Crim.App.2004) (all upholding residency restriction statutes against ex post facto challenges).
. U.S. Const. Art. 1, § 10; KY. Const. § 19(1).

. It is, of course, not identical to traditional banishment, because the registrant may still return to the house during the day, when children are present, so long as he does not make the house his permanent home.
. These same questions were raised by the dissent in People v. Leroy, 357 Ill.App.3d 530, 293 Ill.Dec. 459, 828 N.E.2d 769, 793 (2005) (Kuehn, J., dissenting).
. See Pollard, 908 N.E.2d at 1153 ("Restricting the residence of offenders based on conduct that may have nothing to do with crimes against children, and without considering whether a particular offender is a danger to the general public, the statute exceeds its non-punitive purposes.”).
