Central Illinois vs. Northern Illinois

What This Central Illinois vs. Northern Illinois Comparison Reveals

In FY2024, the Central Illinois District (7th Circuit) handled 549 federal sentencings with an average imposed term of 69.2 months, while the Northern Illinois District (7th Circuit) handled 390 cases at an average of 108.2 months. That is a 39.0-month gap — the Northern District sentences longer on average. Case volume alone tells part of the story: Central processed roughly 1.4× more defendants than Northern, which affects guideline compliance patterns and the mix of offenses each court sees.

Guideline compliance diverges as well. In Central Illinois, 3% of cases were sentenced within the guideline range, 4% above, and N/A% below, with Booker variances in N/A% of dispositions. In Northern Illinois, the corresponding figures were 2% within, 2% above, N/A% below, and N/A% Booker variances. Guilty-plea rates ran at 90% vs. 77%, and prison-sentence rates at 90% vs. 93% respectively — metrics that capture both charging practice and judicial discretion across the two courts.

Set against the nationwide benchmark for the same offense mix, Central Illinois ran a disparity of +15.2% and Northern Illinois ran +25.9%. 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.
