Which do I use? Try the HUD data set reference guide

The U.S. Department of Housing and Urban Development has created a helpful reference guide on HUD USER. It shows which datasets would have most to least relevance in a particular topic area (such as disabilities or demographics).

As reported by APDU: "The Data Set Reference Guide provides convenient, one-stop access to the original data sets generated by the Office of Policy Development and Research (PD&R), including data from the American Housing Survey, HUD median family income limits, microdata on housing discrimination, the HUD-insured multifamily housing stock, HUD’s assisted housing population, and other housing-related topics. Access the PD&R guide here and a guide to other HUD data sources here."

Here is a screenshot of the PD&R guide:
