The population of Brazil is very diverse, comprising many races and ethnic groups. In general, Brazilians trace their origins from three sources: Europeans, Amerindians and Africans. Historically, Brazil has experienced large degrees of ethnic and racial admixture, assimilation of cultures and syncretism. The Brazilian population is said to be the most mixed raced people in the world.[1]

Brazil has conducted a periodical population census since 1872. Since 1940, this census has been carried out decennially. Scanned versions of the forms for each census distributed in Brazil since 1960 are available on-line from IPUMS International.[2] With a total population of 211,531,000 as of 2020, Brazil is the sixth most populated country in the world.
