This court reviews the “substantive reasonableness of the sentence imposed under an abuse-of-discretion standard.” Gall v. United States, 552 U.S. 38, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007). “A discretionary sentence imposed within a properly calculated guidelines range is presumptively reasonable.” United States v. Campos-Maldonado, 531 F.3d 337, 338 (5th Cir.), cert. denied, — U.S.-, 129 S.Ct. 328, 172 L.Ed.2d 236 (2008).
This court has consistently rejected Ga-larza’s “empirical data” argument. See United States v. Duarte, 569 F.3d 528, 529-30 (5th Cir.), cert. denied, — U.S. -, 130 S.Ct. 378, 175 L.Ed.2d 231 (2009). The district court considered Ga-larza’s request for a downward variance, and it ultimately determined that a sentence at the bottom of the applicable guidelines range was appropriate based on the circumstances of the case and the § 3553(a) factors. Galarza’s assertions regarding § 2L1.2’s lack of an empirical basis, the weight given his prior robbery conviction, the nonviolent nature of his offense, and his motive for reentering the United States are insufficient to rebut the presumption of reasonableness. See United States v. Gomez-Herrera, 523 F.3d 554, 565-66 (5th Cir.), cert. denied, — U.S. -, 129 S.Ct. 624, 172 L.Ed.2d 617 (2008). As Galarza has not demonstrated that the district court’s imposition of a sentence at the bottom of the guidelines range was an abuse of discretion, the district court’s judgment is AFFIRMED.
