In brief: The Southern District of California sentenced 32,099 people in fiscal years 2016 to 2025, and immigration (46%) and drug trafficking (41%) made up most of them. 78% of sentences were below the guideline range at the government's request. The median prison term was 15 months, shorter than the 24-month median for all 94 federal districts.
This post uses the U.S. Sentencing Commission's records of 32,099 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.
Immigration and Drug Cases Dominate
Immigration was the largest offense type in the district: 14,718 people sentenced, or 46%. Their median prison term was 6.4 months, and more than 99% pleaded guilty.
Drug trafficking followed with 13,287 people (41%). The median prison term for those cases was 30 months.
Every other offense type was small by comparison. Fraud, theft, and embezzlement accounted for 1,181 people (4%), money laundering for 776 (2%), and firearms for 442 (1%). Child pornography (images of child exploitation) cases numbered 231, with a median prison term of 60 months.
| Offense type | People sentenced | Share of district | Median prison | Pleaded guilty |
|---|---|---|---|---|
| Immigration | 14,718 | 46% | 6.4 months | more than 99% |
| Drug Trafficking | 13,287 | 41% | 30 months | 99% |
| Fraud/Theft/Embezzlement | 1,181 | 4% | 9 months | 98% |
| Money Laundering | 776 | 2% | 15 months | more than 99% |
| Firearms | 442 | 1% | 24 months | 95% |
| Prison Offenses | 285 | less than 1% | 4 months | more than 99% |
| Child Pornography | 231 | less than 1% | 60 months | 96% |
| Administration of Justice | 187 | less than 1% | 12 months | 94% |
Where Sentences Fell Against the Guidelines
Judges calculate a guideline range for every federal case. In this district, 32,063 people had that information recorded.
Of those, 24,998 (78%) received a sentence below the range at the government's request. Within-range sentences were 4,854, or 15%. Across all districts, 48% of sentences were within the range.
Below-range sentences without a government request were 1,838 (6%). Sentences above the range were 373 (1%). The records do not state the reasons for a government request.
Shorter Prison Terms Than the National Median
A prison term was ordered for 30,587 people (95%). The national share was 91%. Probation only, with no prison or other confinement, went to 1,201 people (4%).
The median term for people sent to prison was 15 months. A quarter received 30 months or more, and a quarter received 6 months or less. 8 people received a life sentence.
A mandatory minimum prison term, set by statute, applied to 6,666 people (21%).
Nearly All Cases Ended in a Guilty Plea
Of the 32,099 people sentenced, 31,680 (99%) pleaded guilty. That rate is higher than the 97% for all districts. 419 people were convicted after a trial.
People convicted after a trial and sent to prison (403 of them) had a median term of 51 months. After a guilty plea, the median was 15 months.
Written plea agreements covered 98% of guilty pleas, and 1% were straight pleas with no agreement.
Change Across Fiscal Years
The district sentenced 13,715 people in fiscal years 2016 to 2019 and 18,384 in fiscal years 2020 to 2025. A federal fiscal year runs from October 1 to September 30.
The yearly median prison term was 24 months in 2016 and 9 months in 2025. The table shows every year in between.
| Fiscal year | People sentenced | Median prison | Pleaded guilty |
|---|---|---|---|
| 2016 | 2,849 | 24 months | 98% |
| 2017 | 2,888 | 18 months | 98% |
| 2018 | 3,889 | 15 months | 99% |
| 2019 | 4,089 | 12 months | 99% |
| 2020 | 3,499 | 12 months | more than 99% |
| 2021 | 2,927 | 18 months | more than 99% |
| 2022 | 3,474 | 20 months | 99% |
| 2023 | 3,189 | 18 months | 99% |
| 2024 | 2,634 | 13.2 months | 99% |
| 2025 | 2,661 | 9 months | 99% |
Supervision, Money Penalties, and Criminal History
Supervised release after prison was ordered for 26,043 people (81%), with a median term of 36 months. 14 people (less than 1%) received it for life. Restitution was ordered for 1,047 (3%), and a fine for 514 (2%).
53% of those sentenced were in category I, the lowest criminal history category, and 7% were in category VI, the highest. Court-martial records have no criminal history field.
Bases in the District and What Is Not Counted
Camp Pendleton, Marine Corps Air Station Miramar, and San Diego are in this district and appear in this site's court-martial data. Courts-martial are tried in military courts, not in this federal district court.
The Sentencing Commission data covers only people convicted and sentenced, so acquittals and dismissals are missing. Prison terms are those imposed, not time served, and the data does not show why any case was brought 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 (32,099). 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.
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.
