Most African Americans trace their ancestry to West and Central Africa, where millions of people were forcibly taken during the transatlantic slave trade between the 17th and 19th centuries. The largest share, roughly 39% of all enslaved Africans brought to the Americas, came from West Central Africa, in the region that is now Angola, the Republic of the Congo, and the Democratic Republic of the Congo. The rest came primarily from coastal West Africa, spanning modern-day Senegal to Nigeria. Today, genetic studies show African Americans carry on average 73.2% African ancestry, 24.0% European ancestry, and 0.8% Native American ancestry, reflecting centuries of complex history on American soil.
The Regions of Africa
Between 1650 and 1900, an estimated 10.2 million enslaved Africans survived the Atlantic crossing. Shipping records allow historians to trace where these people were taken from with surprising precision. West Central Africa (Angola, Congo) was by far the largest source at 39%. The Bight of Benin, covering parts of modern Togo, Benin, and western Nigeria, contributed about 20%. The Bight of Biafra, encompassing eastern Nigeria and Cameroon, accounted for roughly 15%. The Gold Coast (modern Ghana) supplied about 10%. Smaller but significant numbers came from Senegambia (4.8%), Upper Guinea including Sierra Leone and Guinea (4.1%), southeastern Africa including Mozambique and Madagascar (5%), and the Windward Coast of Liberia and Ivory Coast (1.8%).
About 388,747 of these enslaved people arrived in North America specifically. The proportions varied by colony and time period, so the ancestry of African Americans does not perfectly mirror the overall Atlantic numbers. Virginia, for example, drew heavily from the Bight of Biafra, while South Carolina’s enslaved population had strong ties to the Upper Guinea coast.
Specific Ethnic Groups and Their Imprint
The people taken from Africa were not a single group. They belonged to dozens of distinct ethnic communities with their own languages, religions, and traditions. Several of these groups left deep marks on African American culture.
The Igbo people of southeastern Nigeria were among the most heavily represented in the Chesapeake colonies. Researchers estimate that between 30% and 45% of enslaved people brought to Virginia came from the Bight of Biafra, and of those, roughly 80% were likely Igbo. At certain points in the 18th century, Igbo people made up over 30% of Virginia’s enslaved Black population, leading some historians to call colonial Virginia “Igbo land.” An estimated 37,000 Africans arrived in Virginia from the port of Calabar during the 1700s, of whom about 30,000 were Igbo. Plantation owners noted what they called “rebellious” attitudes among Igbo captives. Traces of Igbo heritage survive in place names, personal names found in slave records (like “Eboe Sarah”), and cultural traditions. The word “okra” entered English from the Igbo language.
The Yoruba of western Nigeria, the Mende of Sierra Leone, and the Mandinka of Senegambia are other groups with well-documented connections to African American ancestry. Genetic studies using mitochondrial DNA, which traces maternal lineage, confirm that African American maternal ancestry maps closely onto the same broad regions documented in slave trade shipping records.
The Rice Coast and the Gullah Geechee
One of the clearest cultural throughlines connects the Upper Guinea coast to the Lowcountry of South Carolina and Georgia. Enslaved people from the rice-growing region stretching from Senegal to Ivory Coast brought with them a sophisticated knowledge of rice cultivation. South Carolina received some of its first rice in the 1690s aboard a slave ship, and historians argue that Africans established the colony’s rice economy precisely because so many of those enslaved in its early years already knew how to grow the crop.
Enslaved people in the Carolinas even planted their own rice varieties for personal use, distinct from the plantation export crops. One variety was called “Guinea rice,” a name pointing directly to its African origins. This agricultural knowledge system crossed the Atlantic intact. Alongside rice, enslaved Africans introduced sesame to South Carolina by the 1730s. The Gullah Geechee communities of the coastal Southeast still use the word “benne” for sesame, the same term used in West Africa. These communities preserve some of the most direct cultural connections to specific African homelands found anywhere in the United States.
European and Native American Ancestry
Centuries of coerced and, less commonly, consensual relationships between enslaved Black people and white colonists produced significant European admixture in the African American gene pool. Large-scale genomic studies place the average European ancestry of African Americans at about 24%, though this varies widely by individual and region. Some African Americans carry less than 5% European DNA, while others carry more than 50%.
Many African Americans have family stories of Native American heritage, but genetic data tells a more modest story. On average, African Americans carry about 1% Native American ancestry. That small percentage traces back roughly eight to nine generations and likely reflects interactions during the colonial period, when enslaved Africans and Indigenous peoples lived in close proximity. The admixture is real but far less common than family oral traditions suggest.
Modern African Immigration
Not all Black Americans trace their roots to the slave trade. A growing share are first- or second-generation immigrants from Africa and the Caribbean. About one in ten Black people living in the United States today are foreign-born, and the African-born segment of that population has surged. Between 2000 and 2019, the number of Black African immigrants in the U.S. grew 246%, from about 600,000 to 2.0 million. Africans now make up 42% of all foreign-born Black Americans, up from 23% in 2000.
Nigeria is the top sending country, with roughly 390,000 Nigerian-born Black immigrants in the U.S. as of 2019. Ethiopia follows at 260,000, then Ghana at 190,000, Kenya at 130,000, and Somalia at 120,000. Kenya’s immigrant population saw the largest percentage jump at 348% growth over that period. Jamaica and Haiti remain the top countries of origin for Black Caribbean immigrants. These newer arrivals often maintain strong ties to specific ethnic identities and languages, in contrast to the blended heritage that centuries of slavery created among descendants of the earlier forced migration.
