Welcome to IPUMS IHGIS!

September 28, 2020

We are pleased to introduce the initial version of the IPUMS International Historical Geographic Information System (IHGIS). IHGIS provides data tables from censuses of population, housing, and agriculture from around the world, along with corresponding GIS boundary files. This initial release of IPUMS IHGIS includes 270 tables from twelve countries, drawn from nine population censuses and four agricultural censuses.

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 tables and provides them to users in a standardized, machine-readable structure.

We have more than 10,000 additional data tables in the pipeline and plan to release new data on a regular basis. Register now to be the first to know when new data are available and be notified of opportunities to provide feedback on prioritizing datasets for future releases.
