The term mestizo carries different connotations depending on the region.
It is a widely used demographic and cultural category referring to people of mixed European (typically Spanish) and Indigenous American ancestry. It emerged during the colonial era as a caste classification and remains a primary identity for large populations in Mexico, Central America, and the Andes.
The term is not commonly used as an official or social classification. When used, it may occasionally refer to people of mixed Spanish and Romani (Gitano) ancestry, but this usage is rare and not standardized. Spanish demographics typically focus on nationality and regional identities (e.g., Andalusian, Catalan, Basque) rather than racial admixture categories.
Modern Spain recognizes its Gitano population as an ethnic minority, but "mestizo" is not the standard term for them.
