Research and Data

The Public and Affordable Housing Research Corporation (PAHRC) is the research entity
of HAI Group. Our goal is to promote the importance of affordable housing on a national level and to help our stakeholders build evidence-based cases for why affordable housing matters.

Affordable homes are the building blocks of vibrant communities

In addition to educating the public about the impact, outcomes, and benefits that affordable homes bring to families and communities, PAHRC shares data and original findings with thousands of housing providers, policymakers, developers, advocates, and members of the media each year.
