New Hampshire: demographics by county and ZIP code

Olympus publishes Census demographics for 10 counties or county equivalents and 246 ZIP Code Tabulation Areas (ZCTAs) in New Hampshire (ACS 5-year 2020-2024). Each has its own page with population, income, home value, rent, education, poverty and unemployment estimates and their margins of error.

A ZCTA is listed under the state of its primary (2020) county, even when it crosses a state line. Population figures below are ACS 5-year estimates with 90% margins of error.

Data as of Oct 22, 2026 (Olympus publication) · Markdown version

  • ZCTAs are Census statistical areas that approximate USPS ZIP code delivery areas; the code was matched to the ZCTA with the same code, which may not cover the same addresses as the ZIP code.
  • Values are ACS 5-year estimates for 2020-2024 (dollars in 2024 dollars), not current figures.
