Harmonized Geospatial Dataset from the 2010 Brazilian Demographic Census by IBGE

This dataset provides a harmonized geospatial version of the 2010 Brazilian Demographic Census at the census tract level.

The data are distributed as a single GeoPackage file containing cleaned, standardized, and consistently typed attribute tables linked to official census tract geometries. Variable names were harmonized, data types were explicitly enforced, and structural inconsistencies were resolved to facilitate reproducible spatial analysis and integration with GIS and data science workflows.

The original data source is the 2010 Brazilian Demographic Census conducted by the Instituto Brasileiro de Geografia e Estatística (IBGE).

Layers

The GeoPackage includes three structured metadata entry layers:

layers - Describes all database layers contained in the GeoPackage, including geometry type, spatial reference system, thematic scope, and relational structure where applicable.

fields - Documents major attribute fields and naming conventions, including standardized prefixes, identifier variables, geographic codes, and structural variables used for relational integrity and joins.

variables - Provides a complete listing of original census variables, including official variable names, harmonized names (when applicable), and their corresponding descriptions as defined in the 2010 census documentation.

Together, these metadata layers provide full transparency regarding database structure, schema harmonization, and variable provenance.
