The IPUMS International Historical Geographic Information System (IHGIS) provides data tables from population and housing censuses as well as agricultural censuses from around the world, along with corresponding GIS boundary files.
The data in IHGIS were originally published by national statistical offices of the respective countries, primarily in PDF documents. Data tables in these documents vary greatly in structure and are not easy to import into statistical or other analysis software. IHGIS extracts the data from the documents and provides them in a standardized, machine-readable structure.
Through the IHGIS Data Finder, users may select and download data tables from one or more census datasets, potentially covering multiple countries, years, or census types.
Shapefiles representing the units described in the tables are available for download on our Geography & GIS page. (In a future version of IHGIS, these files will be available directly through the Data Finder.) Data tables downloaded from the Data Finder may be joined to these shapefiles using the GISJOIN field in both files.
IHGIS does not provide tools for data analysis, mapping, or reporting. Rather, IHGIS supplies data files designed for use in spreadsheet applications (e.g., Microsoft Excel), statistical software (e.g., R, Stata, SPSS, SAS), or GIS applications (e.g., Esri ArcGIS, QGIS).
IHGIS is funded by a grant from the National Science Foundation with additional support from the Institute for Social Research and Data Innovation.
