The document discusses several national data resources that are available to help with interagency planning efforts at the local level. It summarizes the Housing and Transportation Affordability Index, the TOD Database, On The Map, Policy Map, Foreclosure-Response.org, and the Housing Research and Advisory Service. These resources provide data on housing and transportation costs, transit-oriented development, commuting patterns, community development funding, foreclosures, and housing affordability. The document also asks audience members about their experiences using these resources and what additional data would help local interagency planning.
