Directory listings are mapped to Jefferson County through the US Census Bureau's 2020 ZCTA-to-county relationship file: each ZIP Code Tabulation Area is assigned to the county holding the largest share of its land area, so a small number of churches in ZIP codes that straddle county lines may be attributed to a neighboring county. Congregation and adherent counts come from the 2020 US Religion Census and are reported by the religious bodies themselves. Population is the county's April 2020 decennial-census base from the US Census Bureau's population-estimates program; per-1,000 adherence rates divide reported adherents by that figure.
