Our Data, Your Way!

Now you can interact with IPUMS data products programmatically! IPUMS APIs allow you to explore and retrieve IPUMS data in a whole new way. You can automate and integrate IPUMS data into your own tools and workflows.

Our first public APIs, the IPUMS Metadata and Data Extract APIs, allow you to submit a JSON request to describe the data you want, monitor our progress building your data extract, and download your data when it is ready. Currently it supports IPUMS NHGIS data. IPUMS USA coming soon!
