Montana vs. Northern Mariana Islands

What This Montana vs. Northern Mariana Islands Comparison Reveals

In FY2024, the Montana District (9th Circuit) handled 1,696 federal sentencings with an average imposed term of 30.3 months, while the Northern Mariana Islands District (9th Circuit) handled 97 cases at an average of 75.5 months. That is a 45.2-month gap - the Northern District sentences longer on average. Case volume alone tells part of the story: Montana processed roughly 17.5× more defendants than Northern, which affects guideline compliance patterns and the mix of offenses each court sees.

Guideline compliance diverges as well. Among cases with a determinable guideline range, Montana sentenced 38% within the range, 3% above, and 58% below. In Northern Mariana Islands, the corresponding figures were 66% within, 1% above, and 33% below. Guilty-plea rates ran at 77% vs. 81%, and prison-sentence rates at 90% vs. 85% respectively, metrics that capture both charging practice and judicial discretion across the two courts.

Set against the nationwide benchmark for the same offense mix, Montana ran a disparity of -11.2% and Northern Mariana Islands ran -33.2%. That comparison adjusts for the offense mix each district actually handles, so it isolates court-level patterns from pure caseload composition. Readers should still treat these as aggregate descriptive statistics, individual cases turn on criminal history, specific guideline adjustments, cooperation agreements, and statutory mandatory minimums that the district averages cannot resolve.
