Race and Ethnicity in Chile

Chile’s population is multi‑ethnic, shaped by centuries of mixing between Indigenous peoples and European settlers, with smaller contributions from African, Asian, and other ancestries. Most Chileans identify as Mestizo (mixed Indigenous and European) or White, while Indigenous communities, particularly the Mapuche and Aymara, remain the largest distinct ethnic groups based on self-identification.

Genetic studies show that most Chileans carry a mix of European and Indigenous ancestry, with proportions varying by region and family history. Historical intermarriage and migration patterns have created a complex mosaic of ethnic identities across the country.

According to Latinobarómetro 2024, self-identified ethnic composition shows that 42.2% of Chileans identify as Mestizo, 23.3% as White, and 10.5% as Indigenous. Smaller proportions identify as Black (6.8%), Mulatto (4.5%), or Asian (0.4%), while other races, non-answers, and unsure responses account for the remainder.
