Notes on 2015 QCTs

The 2015 QCTs are based on MSA definitions published in OMB Bulletin No. 10-02 on December 1, 2009 and data from the 2010 Decennial Census and three sets of 5-year tabulations of the American Community Survey (2006 to 2010; 2007 to 2011; and 2008 to 2012). The Census Tract boundaries are according to the 2010 Decennial Census. See the latest Designation Notice for complete information.

Excel spreadsheets containing the data used to designate the 2015 QCTs are available here. The designation algorithm can be read here.

Difficult Development Area Tables

Note: Beginning in 2016, metropolitan DDA designations use small area Fair Market Rents (SAFMRs), rather than metropolitan-area FMRs used in the 2015 and previous designations, as the measure of "construction, land, and utility costs." The 2016 Metropolitan DDAs will therefore be designated at the Census-defined ZIP Code Tabulation Area (ZCTA) level.

While the geographic extent of ZCTAs is very similar to current 5-digit ZIP codes, and the vast majority of ZIP Code areas remain fixed over time, the U.S. Postal Service (USPS) may alter specific ZIP code geography at any time after HUD designates SDDAs. The data from which SAFMRs and SDDA designations are derived, however, does not immediately shift with the USPS definition of ZIP Codes, but remains defined by the ZCTAs as established by the Census Bureau.

The designation methodolgy of non-metropolitan DDAs, defined at the county-level, will remain unchanged.
