Population of Brazil by region, ethnicity and slave status 1872

Brazil conducted its first nationwide census in 1872; this census gave total populations of 4.2 million free non-whites, 1.5 million slave non-whites, and 3.8 million whites. Indigenous people and those of mixed indigenous descent were largely excluded from the census, although an overall figure of 0.4 million was given for the entire country. These figures combined to give a total of 9.9 million (modern UN estimates put the total at 10.3 million in 1872; likely due to the census' exclusion of many non-white infants).

The state of Minas Gerais had the largest population, at over two million people, with the neighboring states of Bahia and Rio de Janeiro with the second and third largest populations respectively. East Brazil was the region with the largest population, followed by the northeast and then south. In terms of ethnicity, non-whites outnumbered white people in every region except for the south, and free people of color outnumbered slaves in every state except for Rio de Janeiro.
