PD&R's primary function is to support HUD's mission and the policy agenda of the Secretary. PD&R performs policy analysis, research, surveys, studies, and evaluations; both short- and long-term; to help the Secretary and other principal staff make informed decisions on HUD policies, programs, and budget and legislative proposals. These activities provide the Department and the nation with current information on housing needs, market conditions, and HUD programs, as well as research on important housing and community development issues.

In addition to its research and policy analysis functions, PD&R has other related responsibilities, including assisting in the oversight of government-sponsored enterprises (GSEs) Fannie Mae and Freddie Mac, providing data support to program office operations, building partnerships with universities that assist their communities, and administering various activities related to the international community.
