Population censuses allow to investigate the evolution of the stock of persons with birth registrations registered in Administrative Registrations of Indigenous Births (RANIs) for this population group.

In this release, the available data include the geographies of Brazil, Major Regions, Federation Units and Municipalities and they are disaggregated according to age groups, color or race and indigenous as well.

The data can be viewed in the Interactive Geographic Platform (PGI), in the Census Overview 2022 and on Sidra.
