Methodology

Source is the NHTSA Fatality Analysis Reporting System (FARS) National CSV downloads for 2018–2024, accessed 2026-08-30. Crashes are selected on STATE = 51 and the FARS COUNTY code 59, not on the CITY code — Arlington County and most of Fairfax County are unincorporated and file CITY as "not applicable", so a city-keyed query returns nothing for them.

Population is the 2020 Decennial Census count (1,150,309). Pedestrian and cyclist deaths come from the person file on INJ_SEV = 4; crossing detail from the FARS pedestrian file joined on (ST_CASE, VEH_NO, PER_NO) and limited to those who died. FARS is fatal-only and will not show serious injuries. The full methodology is on the regional page.
