The Brazilian Institute of Geography and Statistics (IBGE) is Brazil's agency for official statistics and national geography. It produces and distributes the country's administrative boundaries, census tracts and sectors, territorial grids, and cartographic base data.
IBGE's geospatial downloads are essential for any analysis in Brazil that joins data to geography — from municipalities up to the national level — and underpin the census and socioeconomic indicators. Data is freely available through its download services.
