The 20th century saw a large growth of the "pardo" population. In 1940, 21.2% of Brazilians were classified as "pardos". In 2000, they had increased to 38.5% of the population. This is only partially due to the continuous process of miscegenation in the Brazilian population. Races are molded in accordance with perceptions and ideologies prevalent at each historical moment. In the 20th century, a significant part of the Brazilians who used to self-report as Black in earlier censuses chose to move to the Pardo category. Also a significant part of the population that used to self-report as white also moved to the Pardo category with the growing racial and social awareness, and Magnoli describes this phenomenon as the "pardização" ("pardoization") of Brazil.
