About these counts

The Census Bureau counts every independent local government once, in the county it assigns it to: the one it mostly serves or where it's based. A city or district that crosses county lines is counted in only one county, so it may be listed on this page but counted elsewhere, or the other way around. Many special districts, such as housing authorities, have appointed boards, and some places have more than one elected body, so the two columns measure different things. School systems run by a county, city or the state aren't counted as separate governments (1 in Ontario County), though their boards may be listed here; in some states the Bureau counts community or state colleges as school districts. The counts are as of 2022.

About these figures

The American Community Survey asks about 3.5 million households a year about who lives there, their work, income, schooling and housing. The 5-year estimates pool 2020–2024 answers so that every county and district has enough of them. They're estimates with a (larger for smaller places), and they're different from the once-a-decade census count. "Median" means half are above and half below. Household income is before taxes and includes everyone in the household. The unemployment share here is the survey's five-year average, so it differs from the monthly rate in the BLS jobs report. Race and Hispanic origin are as people describe themselves.

Health insurance means any coverage, private or public (such as Medicaid or Medicare), when people answered; the share is of everyone except people on active military duty and people living in institutions such as prisons and nursing homes. The housing shares are of renting households, and of homeowners with a mortgage, for whom the Census Bureau can compute them (households with no income, or renters who pay no cash rent, are left out). Rent here is gross rent, rent plus utilities; owner costs include the mortgage, property taxes, insurance, utilities and fees.

Bureau of Labor Statistics, Local Area Unemployment Statistics, : BLS publishes county figures only that way, so they rise and fall with the seasons; compare a month with the same month a year earlier rather than with the month before. New York's figure above is on the same basis; seasonally adjusted, as in BLS's monthly state release, it was 4.3% in September 2026. The latest month is preliminary and is revised the next month, and BLS revises earlier years each spring. People are counted where they live. October 2025 wasn't collected during the 2025 federal government shutdown, so 2025's yearly average covers 11 months.
