In brief: In the Northern District of Iowa, the median prison term for drug trafficking was 120 months (10 years) among 1,230 people sentenced in fiscal years 2016 to 2025. The median for this offense type across all 94 federal districts was 60 months. A mandatory minimum applied to 82% of the people in the Iowa group.
This post uses the U.S. Sentencing Commission's records of 1,230 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.
A Median Prison Term Higher Than the All-District Figure
Of the 1,230 people, 1,225 (more than 99%) were sentenced to prison, and 4 (less than 1%) received probation only. The median prison term was 120 months. A quarter of those sent to prison received 180 months or more, and a quarter received 68 months or less. 5 people received a life sentence.
For all 94 districts together, the Commission's data shows 185,188 people sentenced for drug trafficking, with 96% sent to prison and a median prison term of 60 months. The Iowa median is higher than that figure. Prison terms here are the terms imposed, not the time actually served.
Mandatory Minimums Were Common
A mandatory minimum prison term applied to 1,012 of the 1,230 people with that information recorded (82%). A mandatory minimum is a floor set by statute, and a judge may not go below it except under limited exceptions.
The records used here do not show which exceptions applied in a given case. They also do not show how many of these terms were set by the minimum rather than by the guideline range.
Where Sentences Fell Against the Guideline Range
The guideline range was recorded for all 1,230 people. A total of 33% (409) were sentenced within the range. Another 41% (501) were below the range at the government's request, and 22% (270) were below it without a government request. 4% (50) were above the range.
Across all districts, 32% of drug trafficking sentences were within the range. For all offense types in the Northern District of Iowa, the figure was 53%. Drug trafficking cases were 35% of the 3,479 people sentenced in this district over the period.
| Fiscal year | People sentenced | Median prison | Pleaded guilty |
|---|---|---|---|
| 2016 | 128 | 96 months | 95% |
| 2017 | 153 | 97.5 months | 91% |
| 2018 | 117 | 121 months | 97% |
| 2019 | 153 | 120 months | 93% |
| 2020 | 99 | 120 months | 96% |
| 2021 | 112 | 120 months | more than 99% |
| 2022 | 117 | 120 months | 92% |
| 2023 | 129 | 120.5 months | 96% |
| 2024 | 101 | 147.5 months | 90% |
| 2025 | 121 | 127 months | 98% |
Guilty Pleas and Trials
Of the 1,230 people, 1,165 (95%) pleaded guilty, and 65 were convicted after a trial. The share pleading guilty was 98% for all districts in this offense type, and 96% for all offenses in this district.
The median prison term after a guilty plea was 120 months. After a trial it was 262 months, based on 64 people convicted at trial and sent to prison. The comparison covers only people who were convicted. Cases that ended in an acquittal or a dismissal are not in the data.
Among guilty pleas, 82% had a written plea agreement, and 18% were straight pleas with no agreement.
Which Guidelines and Which Years
"Drug Trafficking" is the Commission's own category. The primary guideline was §2D1.1 (Unlawful Manufacturing, Importing, Exporting, or Trafficking (Including Possession with Intent to Commit These Offenses)) for 1,097 people. It was §2D1.2 (Drug Offenses Occurring Near Protected Locations or Involving Underage or Pregnant Individuals) for 133.
The group has 551 people in fiscal years 2016 to 2019 and 679 in fiscal years 2020 to 2025. The yearly table shows the median prison term was 96 months in 2016 and 127 months in 2025, with 147.5 months in 2024. The records do not show why the yearly medians moved.
Supervised Release, Fines, and Criminal History
Supervised release after prison was ordered for 1,223 people (more than 99%), with a median term of 60 months. A fine was ordered for 23 (2%), and restitution for 27 (2%).
In criminal history, 20% were in the lowest category I and 24% were in the highest category VI. Court-martial records have no criminal history field, so this post reports federal numbers on their own.
What the Records Cannot Show
The data counts only people who were convicted and sentenced. It does not show the drug type, the quantity, or the facts of any case. It also cannot show why a plea or a trial led to a different prison term, because the groups of cases may differ in ways the data does not record.
How We Counted
Everyone sentenced in federal court in the Northern District of Iowa (U.S. Sentencing Commission district label "Iowa North") in fiscal years 2016 to 2025 whose offense type was "Drug Trafficking" (1,230). 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.
