TYPE OF FILE Summary statistics. SUBJECT CONTENT This product contains summary population counts for two universes, total population and population 18 years and over. The data were derived from the basic questions asked on all census questionnaires. These are often called the 100-percent questions. This file contains four tables: • a count of all persons by race. • a count of the population 18 years and over by race. • a count of Hispanic or Latino and a count of not Hispanic or Latino by race for all persons. • a count of Hispanic or Latino and a count of not Hispanic or Latino by race for the population 18 years and over.

Abstract 1–1 U.S. Census Bureau, Census 2000 Redistricting Data (Public Law 94-171) Summary File State2 County3 Voting district/Remainder County subdivision4 Place/Remainder Census tract Block group Block ‘‘Voting districts’’ is the generic name for areas, such as precincts and wards, established by state and local governments for purposes of elections. States participating in the Census 2000 Redistricting Data Program provided the Census Bureau with boundaries, codes, and (optionally) names, for their voting districts. As an option in the Census 2000 Redistricting Data Program (P.L. 94-171), participating states receive census data for their state legislative districts. These data are included for both the upper and lower chambers. (Nebraska has a unicameral legislature; their legislature is treated as an upper level chamber for data presentation on this file.) Not all states participated in the program. SeeAppendixA,GeographicDefinitionsforamoredetaileddescriptionofthelegislativedis- trict definition/coding scheme and other census geography terms.

RELATED PRODUCTS Public Law 105-119 and Title 15, Code of Federal Regulations, Part 101. The decision whether to release statistically adjusted data will be based on P.L. 105-119 and Title 15, Code of Federal Regulations, Part 101. The Department of Commerce issued this regulation to delegate from the Secretary of Commerce to the Census Bureau Director the authority to make the final determination regarding the methodology (including the possible use of statistical adjustment) to be used in calculating the tabulations of population reported to states and localities under the terms of P.L. 94-171. Public Law 105-119, enacted in 1997, provides for the release of data on ‘‘...the number of persons enumerated without using statistical methods....’’ The data contained in the companion data release to the official P.L. 94-171 Redistricting Data is the Census 2000 Block Data Summary File which supports either P.L. 105-119 or Title 15, Code of Federal Regulations, Part 101. This file (described below) is also available on CD-ROM and through the American Fact- Finder (AFF). This abstract is prepared in advance before the decision of the Director and the advice and rec- ommendation of the ESCAP is known. The following information describes the content of the pos- sible files which will be released simultaneously with the official P.L. 94-171 data. A file containing data which does not reflect statistical corrections for possible overcounts and undercounts using measurements from the Accuracy and Coverage Evaluation (A.C.E.) survey is required if the Direc- tor decided to adjust the P.L. 94-171data.
