OPINION
We must decide whether sentencing a sex offender to a life term of supervised release constitutes “cruel and unusual” punishment under the Eighth Amendment.
I
After having his computer seized by his probation officers, William Vernon Williams admitted that it contained child pornography. Williams told the officers that some of the files depicted incest and child rape. A search of his computer confirmed this admission, showing that he had obtained videos of children as young as ten being raped, and had visited websites that depict graphic sexual violence against children. Williams later admitted to having rape fantasies and being attracted to girls between the ages of nine and sixteen. He also stated that he most enjoyed child pornography that showed men raping children. Williams pled guilty to receipt of child pornography, in violation of 18 U.S.C. § 2252A(a)(2).
This was not the first time that Williams got into trouble for sexual misconduct. In 2000, Williams was convicted in Montana state court of two counts of sexual assault for an incident involving two girls, ages nine and thirteen. The victims were playing outside their home when Williams approached them and asked for hugs. They said “no” and ran away, but Williams, who is 6'4", 285 lbs., followed them into their trailer and cornered them in a bedroom. He then kissed the girls on the lips and neck and squeezed their buttocks. Williams received a ten-year sentence for these crimes, but obtained supervised release in 2001. His supervised release was revoked in 2002, however, because he skipped sex offender treatment sessions and obtained employment at a fair frequented by children.
Because of his sexual assault conviction, the district court in the instant case determined that Williams was subject to a mandatory minimum prison term of fifteen years for his child pornography conviction. See 18 U.S.C. § 2252A(b)(l). The court noted that the Sentencing Guidelines suggested a term of supervised release of five years to life. See U.S.S.G. § 5D1.2(b). The court concluded that a lifetime of supervised release was necessary in order to protect the community from Williams. In making this determination, the court relied on Williams’s prior sexual assault conviction and his apparent obsession with child rape, as indicated by the pornography he possessed and his own statements.
During his supervised release, Williams will be required, among other conditions, to meet regularly with his probation officer, to allow the officer to visit his home, to participate in substance abuse and sex offender treatment, to avoid the company of children, to permit unannounced *1232 searches of his computer, and to comply with the sex offender registration requirements of any state where he resides. The district court did allow Williams to serve his fifteen-year federal sentence concurrently with the undischarged portion of his Montana sexual assault sentence. Williams timely appealed.
II
On appeal, Williams admits that a challenge to his fifteen-year mandatory prison sentence is foreclosed by Ninth Circuit precedent. 1 He also concedes that his sentence of lifetime supervised release was appropriate under U.S.S.G. § 5D1.2(b). He asserts, however, that a life term of supervised release violates the Eighth Amendment’s prohibition against “cruel and unusual punishments,” and is substantively unreasonable.
The Supreme Court has held that the Eighth Amendment contains a “narrow proportionality principle.”
Graham v. Florida,
— U.S. --,
A
There are two ways to succeed on a proportionality claim. The first challenges the sentence as disproportionate “given all the circumstances in a particular case.”
Graham,
Williams does not come close to passing this test. Williams committed very serious crimes: sexually assaulting a nine-year-old girl, sexually assaulting a thirteen-year-old girl, and numerous instances of receiving child pornography. Moreover, although supervised release limits a criminal’s liberty and privacy, it is a punishment far less severe than prison.
Cf. Graham,
A life term of supervised release is particularly appropriate for sex offenders given their high rate of recidivism.
See
H.R. Conf. Rep. No. 107-527, at 2,
Accordingly, we conclude that a life term of supervised release is not unconstitutionally disproportionate given the circumstances of this case.
B
The second way to mount a proportionality challenge is to show that an entire class of sentences is unconstitutionally disproportionate given the severity of the sentence, the gravity of the crime, and the type of offender. Until last Term, the Supreme Court had declared a sentence categorically disproportionate only where the penalty was death.
See Kennedy v. Louisiana,
When considering categorical challenges to classes of sentences, courts look to “objective indicia of society’s standards ... to determine whether there is a national consensus against the sentencing practice at issue,” and to the court’s “own independent judgment.” Id. at 2022 (internal quotation marks omitted).
Here, “objective indicia” suggest that society is comfortable with lifetime sentences of supervised release for sex offenders, as such sentences are common. According to the United States Sentencing Commission, in the last five years, federal courts have sentenced 1875 defendants convicted of child pornography and child prostitution crimes to lifetime supervised
*1234
release.
See
U.S. Sentencing Comm’n,
Federal Offenders Sentenced to Supervised Release
58-59 (July 2010), www.ussc.gov/ generaV20100722_SupervisecLRelease.pdf. By way of comparison, in banning the sentence of life without parole for juvenile nonhomicide offenders, the Supreme Court noted that there were then just 123 people in the county serving such sentences.
See Graham,
In exercising “independent judgment,” the Supreme Court has instructed lower courts to “consider[] whether the challenged sentencing practice serves legitimate penological goals.”
Graham,
Accordingly, we conclude that life terms of supervised release are not categorically disproportionate for sex offenders.
Ill
Williams also asserts that a life term of supervised release is substantively unreasonable.
Appellate courts review the substantive reasonableness of sentences for abuse of discretion, and “must give due deference to the district court’s decision.”
Gall v. United States,
Here, lifetime supervised release is reasonable given the seriousness of Williams’ offenses and the likelihood that he will offend again. The sexual exploitation and abuse of children are unspeakably horrendous crimes. Moreover, those who commit such crimes once are likely to commit them again.
See
H.R. Conf. Rep. No. 108-66, at 49-50, 2003 U.S.C.C.A.N. 683, at 684 (noting that “the perpetrators of child sexual abuse crimes” often have “deep-seated aberrant sexual disorders that are not likely to disappear within a few years of release from prison”). Accordingly, the United States Sentencing Commission recommends the maximum term of supervised release for sex offenses such as receipt of child pornography,
see
U.S.S.G. § 5D1.2(b)(2) (Policy Statement), and several courts of appeals, including our own, have held that life terms of supervised release are reasonable where the
*1235
defendant was convicted of receipt or possession of child pornography,
see, e.g., United States v. Cope,
We conclude that a life term of supervised release is reasonable in this case.
IV
For the foregoing reasons, the district court did not err in sentencing Williams to a fifteen-year sentence, followed by a life term of supervised release.
AFFIRMED.
