  • Full Description
    The American Community Survey (ACS) collects this data from a sample of the population on a rolling monthly basis. 5-year aggregates are released annually. Beginning in 2000, individuals were presented with the option to select one or more races. In addition, the Census asked individuals to identify their race separately from identifying their Hispanic origin. The Census has published individual tables for the races and ethnicities provided as supplemental information to the main table that does not dissaggregate by race or ethnicity. Race categories include the following - White, Black or African American, American Indian or Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, Some other race, and Two or more races. We are not including specific combinations of two or more races as the counts of these combinations are small. Ethnic categories include - Hispanic or Latino and White Non-Hispanic. This data originates from ACS table B01001 and it's racial/ethnic subtables, B01001A through B01001I. The racial/ethnic subtables use a more restrictive set of age cohorts, therefore all data has been aggregated to the bins used by the subtables to keep this dataset uniform. In an effort to greatly reduce bias, variance and standard error, the US Census and ACS have produced a controlled estimate for the total population and for the total Hispanic or Latino population at the State level (Census level 040) - therefore the Margins of Error for these values are listed as zero.
