The Mexican Government asked Mexicans about their perception of their own racial heritage. In the 1921 census, residents of the Mexican Republic were asked if they fell into one of the following categories:
Reference 1: Population and Percentage.
Reference 2: IndÃgena (Indigenous), Mezclada (Mixed), White, Cualquiera otra raza o que se ignora (Either other or chose to ignore the race), Extranjeros, sin distinción de razas (Foreigners without racial distinction) and Total.
