The Census Bureau publishes its most comprehensive data at the county level — covering all 3,143 counties and county-equivalents (parishes, boroughs, municipios) across the United States. Counties are the primary administrative unit below the state and are the building blocks of metro areas.
County data is especially useful for understanding regional variation within a state: income gaps between urban and rural areas, housing affordability differences, and how demographic makeup shifts across a region. Use the rankings to find the counties at the top or bottom of any metric.
