NOTES: Ancestry is a broad concept that can mean different things to different people. The ancestry groups listed on this table were self-identified. The Census Bureau defines ancestry as a person's ethnic origin, heritage, descent, or “roots,” which may reflect their place of birth, place of birth of parents or ancestors, and ethnic identities that have evolved within the United States. Many respondents listed more than one area of ancestry; the sum of the persons reporting the ancestry is greater than the total. Overall, about 500 different ancestries were reported during Census 2000.
1. Group may encompass several ancestries not listed separately.
2. Data is from American Community Survey 5-year estimates 2010–2014.
