In brief: 285 people were sentenced for prison offenses in the Southern District of California in fiscal years 2016 to 2025. 278 (98%) received a prison term, and the median was 4 months, lower than the 10 months for this offense type in all 94 districts. 43% of sentences were within the guideline range.
This post uses the U.S. Sentencing Commission's records of 285 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.
Short Prison Terms
Among the 278 people sent to prison, the median prison term was 4 months. A quarter received 6 months or more, and a quarter received 0 months or less. The records do not explain what a 0-month term represents.
5 people (2%) received probation only. In all districts, 96% of people in this category were sent to prison, and the median was 10 months. For all offenses in the district, the median was 15 months.
What Prison Offenses Means Here
"Prison Offenses" is the U.S. Sentencing Commission's offense category, based on the main guideline in each case. 69 cases used §2P1.1 (Escape, Instigating or Assisting Escape), and 8 used §2P1.2 (Providing or Possessing Contraband in Prison).
These are the most common guidelines in the group. Prison offenses cases were less than 1% of the 32,099 people sentenced in the district.
Criminal History
1% of these people were in the lowest criminal history category, category I, and 18% were in the highest, category VI.
Court-martial records have no criminal history field.
Position Against the Guideline Range
Each case has a guideline range under the Commission's rules. 121 sentences (43%) were within it. For this offense type in all districts, 63% were within the range, and for all offenses in this district, 15%.
102 sentences (36%) were below the range at the government's request, and 59 (21%) were below it without a government request. 1 was above the range. 283 people have this information.
Pleas
283 of the 285 people (more than 99%) pleaded guilty, and 2 were convicted after a trial. In all districts, 99% pleaded guilty.
The median prison term after a guilty plea was 4 months. After a trial it was 21 months, based on 1 person sent to prison; with 1 person in that group, pleas and trials cannot be compared.
92% of guilty pleas had a written plea agreement, and 6% were straight pleas with no agreement. A mandatory minimum prison term applied to 0 of the 263 people with that information.
Supervised Release and Fines
97 people (34%) were ordered to serve supervised release after prison, with a median term of 36 months. No fine and no restitution was ordered.
Cases by Year
101 people were sentenced in fiscal years 2016 to 2019, and 184 in fiscal years 2020 to 2025. The yearly counts range from 20 to 42.
The yearly median was 0 months in 2020 and 2021, and 6 months in 2025. The records cannot show why. Only convictions are counted, and a listed term is the sentence imposed rather than the time served.
| Fiscal year | People sentenced | Median prison | Pleaded guilty |
|---|---|---|---|
| 2016 | 20 | 2.9 months | 95% |
| 2017 | 24 | 4.2 months | 100% |
| 2018 | 29 | 4 months | 100% |
| 2019 | 28 | 4 months | 100% |
| 2020 | 31 | 0 months | 100% |
| 2021 | 39 | 0 months | 100% |
| 2022 | 42 | 4 months | 98% |
| 2023 | 29 | 4.9 months | 100% |
| 2024 | 21 | 3.1 months | 100% |
| 2025 | 22 | 6 months | 100% |
Limits
Nothing in the data describes what any person did. A court-martial would be tried in a military court, so the installations listed for this district (Camp Pendleton, Marine Corps Air Station Miramar, and San Diego) add no cases here.
How We Counted
Everyone sentenced in federal court in the Southern District of California (U.S. Sentencing Commission district label "California South") in fiscal years 2016 to 2025 whose offense type was "Prison Offenses" (285). Offense types are the Commission's OFFGUIDE categories.
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.
