Francisco Antonio Serafin-Rodriguez (Serafin) pleaded guilty without the benefit of a plea agreement to one count of illegally reentering the United States after having been deported. He appeals his 46-month, within-guidelines sentence, arguing that it is substantively unreasonable.

Serafín urges that despite his failure to object to the reasonableness of his sentence in the district court, this court should review the sentence under an abuse-of-discretion standard. He raises the argument only to preserve it for possible future review because, as he recognizes, it is foreclosed and our review is for plain error. United States v. Whitelaw, 580 F.3d 256, 259-60 (5th Cir. 2009). To succeed under this standard, Serafín must show an error that is clear or obvious and that affects his substantial rights, but even so, this court generally will exercise its discretion to correct the error only if it “seriously affect[s] the fairness, integrity, or public reputation of judicial proceedings.” Puc kett v. United States, 556 U.S. 129, 129 S.Ct. 1423, 1429, 173 L.Ed.2d 266 (2009) (citation omitted). Moreover, we presume that his within-guidelines sentence is reasonable. See United States v. Ruiz, 621 F.3d 390, 398 (5th Cir. 2010).

Serafín contends that his sentence is greater than necessary to achieve the purposes of sentencing because the district court did not take into account his cultural assimilation to the United States. Though the district court had the authority to impose a shorter sentence based on this factor, it was not required to weigh Serafin’s cultural assimilation more heavily than other factors. See United States v. Lopez-Velasquez, 526 F.3d 804, 807 (5th Cir. 2008). The court heard and understood Serafin’s arguments for a lower sentence, but merely rejected the contention that his cultural assimilation outweighed his criminal history. See United States v. Gomez-Herrera, 523 F.3d 554, 565-66 (5th Cir. 2008). Specifically, the court found relevant that Serafín committed some of his crimes after illegally reentering the United States and that he had six felony convictions and two misdemeanor convictions. Serafín’s disagreement with the court’s balancing of the relevant factors is insufficient to show that the district court committed error, much less plain error, in imposing a within-guidelines sentence. See Puckett, 129 S.Ct. at 1429; Ruiz, 621 F.3d at 398.

Serafín also contends that the district court mistakenly observed that he burglarized cars for a living. However, this remark is supported in the record because according to the presentence report, though Serafín held jobs in the past, he was unemployed when he was caught breaking into cars and stealing tools. In any event, Serafín does not explain how this statement rendered his sentence substantively unreasonable.

Finally, Serafín argues that his within-guidelines sentence should not be presumed reasonable because § 2L1.2, the illegal reentry Guideline used to determine his sentence, is not supported by empirical data. As Serafin correctly concedes, however, this argument is foreclosed. See United States v. Duarte, 569 F.3d 528, 530-31 (5th Cir.), cert. denied, — U.S. -, 130 S.Ct. 378, 175 L.Ed.2d 231 (2009); United States v. Mondragon-Santiago, 564 F.3d 357, 366-67 (5th Cir.), cert. denied, - U.S. -, 130 S.Ct. 192, 175 L.Ed.2d 120 (2009). Accordingly, Serafin *412 has not shown that the district court committed error, much less plain error. See Puckett, 129 S.Ct. at 1429.

The judgment of the district court is AFFIRMED.
