A focused population profile of Afro-Puerto Ricans, their Puerto Rican and Caribbean background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Afro-Puerto Rican refers to Puerto Ricans with substantial African-descended ancestry, shaped by Spanish colonial history, slavery, emancipation, island regional life, and later migration between Puerto Rico and the mainland United States.
Spanish is the main language of Puerto Rico, with Puerto Rican Spanish central to local identity. English is also important for many Puerto Ricans, especially in diaspora contexts and in parts of public life shaped by Puerto Rico's relationship with the United States.
As a genetic reference, Afro-Puerto Rican is useful for comparison with Afro-Cuban, Unkechaug European+SSA-Mixed, Afro-Venezuelan, Afro-Martinican, Afro-Guadeloupean, Belizean Creole, Swahili Kenya Faza, Swahili Kenya Wasini, Narragansett SSA+European-Mixed, and Swahili Kenya Siyu.
In the World Genetics modern G25 comparison, the closest non-self match for Afro-Puerto Rican is Afro-Cuban. Other nearby references include Unkechaug (European+SSA-Mixed), Afro-Venezuelan, Afro-Martinican, and Afro-Guadeloupean. This gives the Afro-Puerto Rican profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Afro-Puerto Rican ancestry is best interpreted as a Caribbean Latin American profile with African-descended, Iberian/European-related, and Indigenous Taíno or broader Indigenous Caribbean-related layers that vary by family history.
The heatmap should emphasize Puerto Rico, the Spanish Caribbean, the wider Caribbean diaspora, Atlantic Latin America, and comparison zones in West/West-Central Africa and Iberia.
The closest non-self match in this World Genetics comparison is Afro-Cuban. Other nearby references include Unkechaug (European+SSA-Mixed), Afro-Venezuelan, Afro-Martinican, and Afro-Guadeloupean.
In the current modern G25 reference set, Afro-Cuban is the closest listed match to the Afro-Puerto Rican average after removing Afro-Puerto Rican itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Afro-Puerto Rican G25 average, giving the closest-match results a geographic view.
