Covering 8.5 million square kilometers, Brazil is the world's fifth-largest nation by land area. To govern this immense territory, Brazil is organized as a federation of 26 states (estados) and one Federal District (Distrito Federal), which houses the modernist capital, Brasília.
The Constitutional Framework
Brazil's current territorial structure was codified by the 1988 Federal Constitution. Unlike unitary states, Brazilian states possess their own state constitutions, unicameral legislative assemblies, and directly elected governors with jurisdiction over public safety, regional highways, and secondary education.
The Five IBGE Macro-Regions
To facilitate statistical analysis and regional planning, the Brazilian Institute of Geography and Statistics (IBGE) groups the 26 states into five official macro-regions:
1. The North (Região Norte)
Encompassing seven states (Amazonas, Pará, Acre, Rondônia, Roraima, Amapá, and Tocantins), the North covers over 45% of Brazil's total area. It is characterized by the Amazon basin, dense tropical rainforest, indigenous reservations, and equatorial rivers.
2. The Northeast (Região Nordeste)
Comprising nine coastal and interior states, the Northeast is Brazil's historic colonial heartland. It spans the dry sertão scrubland and idyllic Atlantic beaches, preserving rich Afro-Brazilian culture and historic UNESCO architecture in Salvador and Olinda.
3. The Central-West (Região Centro-Oeste)
Consisting of Goiás, Mato Grosso, Mato Grosso do Sul, and the Federal District, this region features the vast tropical savanna (Cerrado) and the Pantanal wetland. It is the powerhouse of Brazilian agricultural exports (soybeans, maize, beef).
4. The Southeast (Região Sudeste)
Home to São Paulo, Rio de Janeiro, Minas Gerais, and Espírito Santo, the Southeast contains over 40% of Brazil's population and produces more than half of the national GDP. It is the industrial, financial, and cultural focal point of South America.
5. The South (Região Sul)
Paraná, Santa Catarina, and Rio Grande do Sul enjoy a subtropical and temperate climate with pronounced seasonal shifts. Settled heavily by 19th-century German, Italian, and Polish immigrants, it features high human development indices and rich agricultural output.
