American ancestry

American ancestry refers to people in the United States who self-identify their ancestral origin or descent as "American", rather than the more common officially recognized racial and ethnic groups that make up the bulk of the American people. The majority of these respondents are visibly White Americans, who are far removed from and no longer self-identify with their original ethnic ancestral origins. The latter response is attributed to a multitude of generational distance from ancestral lineages, and these tend be Anglo-Americans of English, Scotch-Irish, Welsh, Scottish or other British ancestries, as demographers have observed that those ancestries tend to be recently undercounted in U.S. Census Bureau American Community Survey ancestry self-reporting estimates.

Although U.S. census data indicates "American ancestry" is most commonly self-reported in the Deep South, the Upland South, and Appalachia, a far greater number of Americans and expatriates equate their nationality not with ancestry, race, or ethnicity, but rather with citizenship and allegiance.
