This page allows you to download an Excel spreadsheet containing all of the data used to designate the 2018 Qualified Census Tracts for each population cap area (metropolitan area or nonmetropolitan part of state). The data include: 2010 Census SF-1 (100 percent count) data tabulations on total population, number of households, and popoulation in group quarters (not in households); 2009-2013, 2010-2014 and 2011-2015 American Community Survey (ACS) 5-year data tabulations on persons in poverty, persons for whom poverty status has been determined, and tract median household income, as well as the margins of error (90 percent confidence interval) for each of these etimates.
A description of the QCT Designation algoritm is available here.
You may select up to 10 metropolitan areas or state nonmetropolitan areas in a single extract. Hold down the <Ctrl> key to select multiple areas. If you select more than 10 areas, only the first 10 you picked in the order listed in the select box will be processed. Data for all of the census tracts in the United States and Puerto Rico can be downloaded here. Note that the full data download file QCT_DATA.zipx is a WinZip archive containing an Excel 97-2003 compatible workbook file: qct_data_2018.xls, containing 6 worksheets: (1) data for the states of Alabama through Missouri; (2) data for the states of Montana through Wyoming and Puerto Rico; (3) data definitions; (4)state code translations; (5) county code translations; and (6) Metro CBSA Code translations. This file must be extracted before it can be read. The tract data are divided over 2 worksheets because there is a total of 74,002 Census Tracts in the data file, which is more cases than Excel 97-2003 is capable of displaying in one worksheet. Analysis of all of the tract data will require Excel 2007 or better, Microsoft Access, or statistical analysis software such as SAS, SPSS, or STATA.
(NOTE: Double-clicking a Metropolitan Area or State Name will not work. Choose Metropolitan Area(s) or State(s) and click the "Get Excel Data" button below your choice.)
