Unfortunately, we are no longer able to support IPUMS Terra (including the Extract Builder, TerraClip, and TerraScope), and these systems have been decommissioned as of October 2022.
Most of the data that were in IPUMS Terra are available through other sources.
- Microdata are available via IPUMS International
- Area-level population data are available via IPUMS IHGIS. IHGIS includes data from the published results of dozens of censuses, with additional datasets added regularly. The datasets in IHGIS typically include a much more extensive selection of tables than those currently available in Terra, particularly for censuses not included in IPUMS International. In addition, data tabulated from IPUMS International microdata that were available in IPUMS Terra are now available via IHGIS. See the "Microdata Sample Tabulations" section in the datasets filter.
- Boundary shapefiles are available for download from IPUMS International and/or IHGIS, depending on which project houses the associated population data.
- Raster data on land use, land cover, and climate are available from the data producers. Find links and additional information on our raster data sources page.
While the base data are still available, the functionality to transform among data structures on the Terra platform has been lost. We plan to provide a collection of resources with guidance for conducting these transformations on your own.
We are also working toward preserving selected transformed data, particularly area-level summaries of raster data, as static files available for download. However, due to the number of raster variables, time points, and boundary shapefiles, it is not feasible to capture every possible combination.
In addition, we are hoping to identify partners and funding to eventually carry this functionality forward into other projects.
