This page allows you to download an Excel spreadsheet containing all of the data used to designate the 2010 Qualified Census Tracts for each population cap area (metropolitan area or nonmetropolitan part of state). The data include: 2000 Census SF-1 (100 percent count) data tabulations on total population, number of households, and popoulation in households; 2000 Census SF-3 (sample) data tabulations on persons in poverty and persons for whom poverty status has been determined; and 2000 Census special tabulations of sample household income data that are more detailed (36 cells) than those provided in the 2000 Census SF-3 Table P052 (16 cells plus total households).
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_US.zip is a WinZip archive containing 2 files: qct_data.dbf, a dBase file containing the data; and QCT Data Documentation.xls, an Excel file containing data definitions and geographic code translations. These files must be extracted before they can be read. While Excel can open dBase files, qct_data.dbf contains more cases than Excel is capable of displaying, so analysis of the full file will require 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.)
