Our data has a comprehensive set of metadata that documents its availability and meaning. We have created endpoints to allow users to explore this metadata. These endpoints are part of our Metadata APIs. These metadata endpoints are useful for helping users understand which data is available across our datasets, and also for helping users construct their extract request.
See example code showing how to use the Metadata APIs to interact with IPUMS microdata metadata (coming soon) and IPUMS NHGIS metadata.
API BETA PROGRAM STATUS: Currently, metadata about our IPUMS NHGIS aggregate datasets is available through these endpoints. IPUMS USA microdata metadata will be available soon.
