Demographic Data Sources

Sources of U.S. Data and their Limitations

  1. Federal Census Data www.census.gov
    1. LIMITATION: Traditionally undercounts ethnic subpopulations
    2. LIMITATION: Federally defined minority categories used in most analyses (American Indian and Alaska Native; Asians; Pacific Islanders; Black or African American; Hispanic or Latino) lump different populations together making data on individual ethnic groups (e.g., Chinese American, Navajo, Mexican American) difficult to access.
    3. LIMITATION: Differentiating race and ethnicity: Overlap and confusion between the racial categories used in census data (American Indian/Alaska Native, Asian; Pacific Islander; Black; and White) and Hispanic, which is an ethnic category; individuals in Hispanic category can be of any race and are counted in those categories as well unless the data is labeled “non-Hispanic” (e.g., non-Hispanic White).
    4. Demographic characteristics available include age, gender, housing, income/poverty, marital status, living arrangements, education, language spoken at home, and English fluency.
