2008 IBGE data for the regions and states sampled in this study.

The first column shows the total population of Brazil and the population of each state expressed in absolute values and percentage of the total for the whole Country. The columns for the color categories contain data also expressed in absolute numbers and percentages self-categorized in that region (in parentheses). The percentages for Whites, Blacks and Browns do not add to 100% because each State has individuals who belong to color categories that are distinct from the ones shown. Data obtained from http://www.sidra.ibge.gov.br/bda/tabela/listabl.asp?z=t&c=262.
