A note on data vintages and definitions. Population is the US Census Bureau's 2018-2022 American Community Survey 5-year estimate. Sheriff staffing is not currently loaded for Illinois, so the staffing columns show a dash throughout this table. They previously carried the US Census Bureau's Census of Governments Employment 2022 figure, which counts a county government's police protection and corrections employment by function code rather than by agency. That total includes the county probation department, the coroner and the crime lab, and it excludes the sheriff's own court services staff, so it does not describe a sheriff's office. Staffing will return here when a county-published figure is loaded. County jail data has not yet been loaded for Illinois; the eventual source is expected to be the Illinois Department of Corrections' Jail and Detention Standards Unit, which inspects each county jail annually under 730 ILCS 5/3-15-2 but publishes results as per-county, per-year PDF reports rather than a single consolidated roster. Sheriff department budget data has not yet been loaded for Illinois. Sheriff names were collected from the Illinois Sheriffs' Association directory and machine-verified against county sources in July 2026.
