The IPUMS spatial team is excited to introduce two new products that expand the ways you can access NHGIS data. IPUMS GeoMarker enables you to easily attach contextual characteristics from ACS data to address or point data, and the first public IPUMS API provides programmatic access to NHGIS data and metadata. Both products officially moved out of beta in December 2019.
