Where the Milwaukee County numbers come from
Counted from NHTSA's Fatality Analysis Reporting System, 2024 Annual Report File: every fatal crash NHTSA filed in Milwaukee County (county code 79). A fatal crash is one in which someone died within 30 days. The rate per 100,000 uses the Census Bureau's population estimate for the county; it is the only figure here not counted from FARS. Totals from state highway departments and news reports can differ: they count from their own crash reports, often before every death within 30 days is known, while NHTSA's file is checked against death certificates and revised once a year.
