Jon and Marie: I forwarded these responses to Robert Renner at HUD. Because of the inclusion of business lists with housing lists, I believe HUD has had the same issues with comparing the data. They are trying to get USPS to separate out housing units and businesses in the future.

The ACS county-level vacancy data appear far more accurate in our area, but they are not available at the tract level yet. However, the HUD data do appear to reflect different characteristics of tracts - they correctly identify areas of generally higher vacancy. Therefore, I may be able to use the HUD figures to identify changes in vacancy by tract over time. The HUD figures do not separate businesses from residences. Therefore, like so many other sources, they are useful but not fully compatible with other data sets.
