[CTPP] HUD / USPS vacancy data

[Nanda.Srinivasan at dot.gov]

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. 
Thanks
Nanda

Like Ms. Bousefield in Chicago, I find the HUD vacancy figures running 
very low. 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.
