[CTPP] Vacancy Rates by quarter

This is with regard to questions on vacancy rates by season. I recently had a chat with Jon Sperling at HUD (during a walk on the mall) and he pointed me to these datasets (acquired from USPS) that list vacancy rates for each census tract by quarter and year. http://www.huduser.org/datasets/usps.html I have not used these much, but am intrigued. The datasets are comparatively new (introduced in December 2006). HUD is looking for user feedback. I found that the data can be joined and easily plotted using a nationwide Census Tract shapefile. I can see quite a few applications in examining these data for transportation planning applications. Also see the data dictionary at http://www.huduser.org/datasets/usps/USPS_Data_Dictionary.pdf The contact person for these datasets is Robert Renner <mailto:Robert.N.Renner@hud.gov> .
