Census › Maryland

Maryland

Figures from the 2020-2024 American Community Survey five-year estimates (table codes link to the same table for this area at data.census.gov) and the 2020 census (P1), via IPUMS NHGIS. Estimates for small areas carry wide margins of error; a tract's figures describe its residents, not any one organization.

Census figures are from IPUMS NHGIS: the American Community Survey 2020-2024 five-year estimates (ACS table codes shown with each figure) and the 2020 decennial census (Demographic and Housing Characteristics), by state, county, place and census tract. FURP records are placed by ZIP code (the Census Bureau's 2020 ZCTA-to-county and ZCTA-to-tract relationship files: the county or tract holding most of the ZIP's land) and by city name (Census place names, normalized), so a record's tract is its ZIP's main tract, not its street's.
