Summary View help for Summary
Public Law 94-171, enacted in 1975, requires the Census Bureau to provide redistricting data in a format requested by state governments. Within one year following the 1990 decennial Census (by April 1, 1991), the Census Bureau provided the governor and legislature of each state with the population data needed to redraw legislative districts. This collection contains the same substantive and geographic variables as the original Public Law 94-171 files [see CENSUS OF POPULATION AND HOUSING, 1990 [UNITED STATES]: PUBLIC LAW (P.L.) 94-171 DATA (ICPSR 9516)] but with the population counts adjusted for undernumeration. Adjusted Public Law 94-171 counts are supplied for a sample of one-half of blocks in the United States and a complete selection of areas with 1,000 or more persons. Each state file provides data for the state and its subareas in the following order: state, county, voting district, county subdivision, place, and block. Additionally, complete summaries are provided for the following geographic areas: county subdivision, place, consolidated city, state portion of American Indian and Alaska Native area, and county portion of American Indian and Alaska Native area. Area characteristics such as land area, water area, latitude, and longitude are provided. Summary statistics are provided for all persons, for persons 18 years old and over, and for housing units in the geographic areas. Counts by race and by Hispanic and non-Hispanic origin are also recorded.

(1) Census tracts and block groups are not included in these files. (2) These data files were obtained from the United States House of Representatives, who received them from the Census Bureau accompanied by the following caveats: "The numbers contained herein are not official 1990 decennial Census counts. The numbers represent estimates of the population based on a statistical adjustment method applied to the official 1990 Census figures using a sample survey intended to measure overcount or undercount in the Census results. On July 15, 1991, the Secretary of Commerce decided not to adjust the official 1990 decennial Census counts (see 56 Fed. Reg. 33582, July 22, 1991). In reaching his decision, the Secretary determined that there was not sufficient evidence that the adjustment method accurately distributed the population across and within states. The numbers contained in these tapes, which had to be produced prior to the Secretary's decision, are now known to be biased. Moreover, the tapes do not satisfy standards for the publication of Federal statistics, as established in Statistical Policy Directive No. 2, 1978, Office of Federal Statistical Policy and Standards. Accordingly, the Department of Commerce deems that these numbers cannot be used for any purpose that legally requires use of data from the decennial Census and assumes no responsibility for the accuracy of the data for any purpose whatsoever. The Department will provide no assistance in interpretation or use of these numbers."
