Population Characteristics of the Seattle-Puget Sound Registry (2020 Census Data1)

Race/Ethnicity Both Sexes % of Total Registry Population
  1. Source: U.S. Bureau of Census, Census 2020, DEC Redistricting Data (PL 94-171), Tables P1, P2
  2. Total Population equals the sum of the White, Black, American Indian/Alaska Native, Asian, Native Hawaiian/Pacific Islander, Other Race, and Two or More Races.
  3. Since each person could report multiple races in the 2020 Census, race-specific counts and percentages in this table are based on persons self-reporting only one race.
  4. Hispanic ethnicity is tabulated independently of race, so Hispanic persons may be of any race.
