About the data

U.S. Census Bureau, American Community Survey 2020–2024 5-year estimates, released December 2025: the most recent data for small areas. Boundaries: Census cartographic boundary files.

Two counting systems are used and never mixed. The 8 major groups and the Hispanic/Latino origins are mutually exclusive: each person is counted once. Asian origins are counted "alone or in any combination": someone who reports two origins is counted in both, so Asian origin figures overlap and cannot be added up.

ACS figures are survey estimates, not a full count. The map shows each estimate's 90% margin of error, and hatches any estimate whose coefficient of variation is above 40%.
