“The Census Bureau, in response to federal and state officials as well as other data users, is providing an early version of table P42 from the 2010 Census Summary File 1, showing population counts for seven types of group quarters. The institutionalized group quarters categories include correctional facilities for adults, juvenile facilities, nursing facilities/skilled-nursing facilities and other institutional facilities; while the noninstitutionalized group quarters categories include college/university student housing, military quarters and other noninstitutional facilities. Data are shown for states, counties, census tracts and blocks. This early release will be useful to data users in the redistricting community who must follow state legislation regarding group quarters populations in redrawing boundaries. This table will only be available via the FTP site and is identical to table P42 in Summary File 1 to be released this summer. At that time, characteristics of the group quarters population will also be available. More information about the definitions of the group quarters types and how to use the summary file can be found in the documentation accompanying the data on the FTP site and here in PDF.
