Arizona vs. Montana

What This Arizona vs. Montana Comparison Reveals

In FY2024, the Arizona District (9th Circuit) handled 108 federal sentencings with an average imposed term of 97.8 months, while the Montana District (9th Circuit) handled 1,696 cases at an average of 30.3 months. That is a 67.5-month gap — the Arizona District sentences longer on average. Case volume alone tells part of the story: Montana processed roughly 15.7× more defendants than Arizona, which affects guideline compliance patterns and the mix of offenses each court sees.

Guideline compliance diverges as well. In Arizona, 3% of cases were sentenced within the guideline range, 3% above, and N/A% below, with Booker variances in N/A% of dispositions. In Montana, the corresponding figures were 35% within, 0% above, N/A% below, and N/A% Booker variances. Guilty-plea rates ran at 72% vs. 77%, and prison-sentence rates at 95% vs. 90% respectively — metrics that capture both charging practice and judicial discretion across the two courts.

Set against the nationwide benchmark for the same offense mix, Arizona ran a disparity of +14.3% and Montana ran -11.2%. 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.
