Black and African Americans constitute the third largest racial and ethnic group in the United States (after White Americans and Hispanic and Latino Americans). Most African Americans are descendants of enslaved peoples within the boundaries of the present United States. On average, African Americans are of West/Central African and European descent, and some also have Native American ancestry. According to U. S. Census Bureau data, African immigrants generally do not self-identify as African American. The overwhelming majority of African immigrants identify instead with their own respective ethnicities (≈95%). Immigrants from some Caribbean, Central American and South American nations and their descendants may or may not also self-identify with the term.
