Chart of Alabama Racial Breakdown of Population (1990-2010)

The largest reported ancestry groups in Alabama are: African (26.2%), English (23.6%), Irish (7.7%), German (5.7%), and Scots-Irish (2.0%). Those citing "American" ancestry in Alabama are generally of English or British ancestry; many Anglo-Americans identify as having American ancestry because their roots have been in North America for so long, in some cases since the 1600s. Demographers estimate that a minimum of 20–23% of people in Alabama are of predominantly English ancestry and that the figure is likely higher. In the 1980 census, 41% of the people in Alabama identified as being of English ancestry, making them the largest ethnic group at the time.
