Montana vs. Southern California

What This Montana vs. Southern California 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 Southern California District (9th Circuit) handled 286 cases at an average of 67.7 months. That is a 37.4-month gap — the Southern District sentences longer on average. Case volume alone tells part of the story: Montana processed roughly 5.9× more defendants than Southern, which affects guideline compliance patterns and the mix of offenses each court sees.

Guideline compliance diverges as well. In Montana, 35% of cases were sentenced within the guideline range, 0% above, and N/A% below, with Booker variances in N/A% of dispositions. In Southern California, the corresponding figures were 10% within, 1% above, N/A% below, and N/A% Booker variances. Guilty-plea rates ran at 77% vs. 91%, and prison-sentence rates at 90% vs. 92% 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 Southern California ran -24.6%. 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.
