In brief: In fiscal years 2016 to 2025, 3,269 people were sentenced in federal court under §2A3.5, failure to register as a sex offender. 96% received prison, the median prison term was 18 months, and 99% pleaded guilty. A mandatory minimum applied to 5 people.
This post uses the U.S. Sentencing Commission's records of 3,269 people sentenced in federal court in fiscal years 2016 to 2025. Acquittals and dismissals come from a second source, the Federal Judicial Center's records of 753,808 federal defendants whose cases ended in fiscal years 2016 to 2025. It is part of the Federal Prosecution Analysis series, which builds on Military Moves Toward Sentencing Guidelines to Mirror the Federal System. How the numbers were built: How the Federal Comparison Data Was Built.
The Median Was 18 Months in Nearly Every Year
Guideline §2A3.5 is titled "Failure to Register as a Sex Offender." The yearly median prison term was 18 months in every fiscal year from 2016 to 2025 except 2017, when it was 20.5 months. Fiscal years 2016 to 2019 had 1,531 people, and fiscal years 2020 to 2025 had 1,738. Each period had a median of 18 months.
The yearly count of people sentenced fell from 427 in 2016 to 257 in 2021. It was 310 in 2024 and 291 in 2025. The records do not show why the counts changed. A drop in the count does not by itself show a change in how many people failed to register, because the data counts only people who were convicted and sentenced.
| Fiscal year | People sentenced | Median prison | Pleaded guilty |
|---|---|---|---|
| 2016 | 427 | 18 months | 99% |
| 2017 | 384 | 20.5 months | 99% |
| 2018 | 360 | 18 months | more than 99% |
| 2019 | 360 | 18 months | more than 99% |
| 2020 | 291 | 18 months | 99% |
| 2021 | 257 | 18 months | more than 99% |
| 2022 | 307 | 18 months | 97% |
| 2023 | 282 | 18 months | 98% |
| 2024 | 310 | 18 months | 98% |
| 2025 | 291 | 18 months | more than 99% |
Prison and Probation
Of 3,269 people sentenced, 3,140 (96%) received a prison term, and 87 (3%) received probation only. A quarter of the prison terms were 26 months or more, and a quarter were 12 months or less. Probation only means no prison or other confinement was ordered.
Pleas and Plea Agreements
3,227 people (99%) pleaded guilty, and 42 were convicted after a trial. Among the guilty pleas, 68% had a written plea agreement, and 32% were straight pleas with no agreement.
The median prison term was 18 months after a guilty plea and 28.5 months after a trial. The trial figure comes from 40 people, which is a very small group, so it is a weak basis for a comparison.
Mandatory Minimums Almost Never Applied
A mandatory minimum prison term applied to 5 people, which is less than 1%. The sheet does not say what set the sentence in the other cases, so no reason is given here for any one result.
The Commission also records where each sentence fell against the range. Of 3,269 cases with the information, 55% (1,809) were within the range. 11% (352) were below it at the government's request, and 29% (963) were below it without a government request. 4% (145) were above the range.
Supervised Release After Prison
Supervised release was ordered for 3,117 people (95%). The median term was 60 months, and 88 people (3%) received supervised release for life. A fine was ordered for 99 (3%), and restitution for 9 (less than 1%).
Criminal History
Criminal history was weighted toward the high end here. 5% of people were in the lowest category, and 18% were in the highest. Court-martial records have no criminal history field, so the military cannot be compared on this point. Criminal history category is a federal measure of a person's prior record, and the data lists the lowest and highest categories only.
What the Records Do Not Show
The approved crosswalk has no close court-martial counterpart for this guideline, so only federal numbers appear. The data counts only people who were convicted and sentenced, and it reports terms imposed rather than time served. It does not show the circumstances of the registration failure in any case.
How We Counted
Everyone sentenced in federal court in fiscal years 2016 to 2025 whose primary sentencing guideline was §2A3.5 (3,269), from the U.S. Sentencing Commission's individual data files. The primary guideline is the one that set the offense level for the most serious count.
Federal fiscal years run from October 1 to September 30. No person, judge, or lawyer is identified in any of these records.
What to Keep in Mind
No parole in federal prison; credit for good conduct. Federal prison has no parole for crimes committed on or after November 1, 1987. A federal prisoner can earn up to 54 days of good conduct credit for each year of the sentence the judge imposed, which is about 15%. Some federal prisoners can also earn First Step Act time credits, but many offenses make a person ineligible. The numbers in this post are the sentences judges imposed, not the time people actually served.
Federal supervised release. Most federal prison sentences are followed by a term of supervised release that the judge sets as part of the sentence. A person who violates it can be sent back to prison. A court-martial cannot sentence anyone to supervision after release. Military parole and mandatory supervised release are decided later by a board, not by the judge at trial.
Who decides the sentence, and under what rules. Federal judges sentence every federal case. They must calculate the Sentencing Guidelines range, which is advisory, and must impose any mandatory minimum the statute requires unless an exception applies. In courts-martial, the accused could choose sentencing by members until the rules changed. For cases in which every guilty finding is for an offense committed after December 27, 2023, a military judge sentences alone, within sentencing parameters. Courts-martial tried in 2024 and later include both old-rule and new-rule cases, and the data cannot tell them apart.
Time periods. Federal numbers are by federal fiscal year (October 1 to September 30), based on the sentencing date. The military numbers are by trial date. Neither source has the date of the offense, so a change in law shows up in either data set gradually.
How life sentences and "time served" are counted. In the federal numbers, a life sentence is counted as 470 months, and any other sentence longer than 470 months is counted as just under 470 months. A sentence of "time served" is counted as one day (0.03 months). Averages are affected by these rules; medians much less.
Mandatory minimum sentences. Many federal statutes on drugs, images of child exploitation, child sex abuse, and firearms carry mandatory minimum prison terms. The UCMJ has mandatory minimums only for a few offenses (a dishonorable discharge or dismissal for rape and sexual assault, and life for premeditated murder). Federal sentences for these offenses are partly set by Congress, not by the judge.
