What explains this paradox?

The pattern is clear: South and Southeast regions concentrate the greatest educational opportunities, higher per capita income and access to better quality health services. While São Caetano do Sul offers the best education, higher income and better public services, Melgaço struggles with illiteracy rates and lower income.

The historical dimension matters: industrialization concentrated in the Southeast, unequal regional policies and investment in infrastructure created this very unequal geography of opportunities.

Methodology and Sources

Data originating from:

• IBGE Census 2022 — population and socioeconomic structure
• UNDP/IBGE HDI — reference 2010, still adopted as standard indicator
• Score de Cidades — compilation and comparative analysis

Brazil's HDI is being updated in 2026. These numbers reflect the last consolidated official measurement.

Frequently Asked Questions
