This map shows an estimate of the average IQ for each census tract (Setor Censitário) in the IBGE 2022 Census.

To calculate the average IQ for each sector, a weighted average was used. This method considers the number of people of each race in the sector and the average IQ values associated with each race:

• Asians: 103
• Whites: 96
• Mixed-race (pardos): 90
• Blacks: 85
• Indigenous: 84

Sources for the average values:

• Lynn, Richard, and Tatu Vanhanen. IQ and the wealth of nations. Bloomsbury Publishing USA, 2002.
• Herrnstein, Richard J., and Charles Murray. The bell curve: Intelligence and class structure in American life. Simon and Schuster, 2010.
