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 API. 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 API to interact with IPUMS NHGIS metadata. Our microdata products don’t yet have support in the Metadata API, but see the IPUMS USA metadata and IPUMS CPS metadata for more information and workarounds.
