Roberto Aguilar, Jr., pleaded guilty to the charge of being found illegally in the United States after having been deported. See 8 U.S.C. § 1326. Because Aguilar had a prior conviction for robbery, his offense level was adjusted upward by 16 levels pursuant to U.S.S.G. § 2L1.2(b)(1)(A)(ii). After granting the Government’s request for a two-level downward departure for early disposition under § 5K3.1, p.s., the district court sentenced Aguilar to a 37-month term of imprisonment, at the bottom of the guidelines range. Aguilar appeals his sentence, arguing that it is unreasonable. In reviewing a sentence, we “consider the substantive reasonableness of the sentence imposed under an abuse-of-discretion standard.” Gall v. United States, — U.S. -, -, 128 S.Ct. 586, 597, 169 L.Ed.2d 445 (2007).

Aguilar argues that § 2L1.2 is not empirically based and should be accorded little weight in the 18 U.S.C. § 3553(a) analysis. Because Aguilar did not raise this argument in the district court, plain error review applies. See United States v. Baker, 538 F.3d 324, 332 (5th Cir.), cert. denied, - U.S. -, 129 S.Ct. 962, 173 L.Ed.2d 153 (2009). Aguilar has not shown error, plain or otherwise. See United States v. Campos-Maldonado, 531 F.3d 337, 338-39 (5th Cir.), cert. denied, - U.S. -, 129 S.Ct. 328, 172 L.Ed.2d 236 (2008); United States v. Gomez-Herrera, 523 F.3d 554, 565-66 (5th *729 Cir.), cert. denied, — U.S. -, 129 S.Ct. 624, 172 L.Ed.2d 617 (2008).

Aguilar is essentially asking this court to reweigh the § 3553(a) factors, which we may not do. See Gall, 128 S.Ct. at 597. The totality of the circumstances, considered in light of the § 3553(a) factors, supports the sentence the district court imposed. See id.

AFFIRMED.
