Notes on 2017 QCTs:

Effective date: The effective date of the 2017 QCTs and DDAs is January 1, 2017.

The 2017 QCTs are based on MSA definitions published in OMB Bulletin No. 13-01 on February 28, 2013 and data from the 2010 Decennial Census and three sets of 5-year tabulations of the American Community Survey (2008 to 2012; 2009 to 2013; and 2010 to 2014). 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 2017 QCTs are available here. The designation algorithm can be read here.

Difficult Development Area Tables

Nonmetropolitan Difficult Development Areas

County-based DDAs:

Information on Small Difficult Development Areas (SDDAs):

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. Therefore, for purposes of determining 2016 and 2017 SDDA status, users should refer to the DDA (ZCTA) address locator at http://www.huduser.gov/portal/sadda/sadda_qct.html rather than the USPS-assigned 5-digit ZIP Code of the project.

The Difficult Development Area tables are available as Adobe Acrobat (*.PDF) files formatted for optimal printing.
