Census of Population and Housing, 2000 [United States]: Public Law (P.L.) 94-171 Data, National File (ICPSR 13341)

Principal Investigator(s):

Summary:

Public Law 94-171, enacted in 1975, directs the United States Census Bureau to make special preparations to provide redistricting data needed by the 50 states. It specifies that within one year following the Census Day (i.e., for Census 2000 by April 1, 2001), the Census Bureau must send the governor and legislature in each state the data they need to redraw districts for the United States Congress and state legislatures. The National file provides data in a hierarchical sequence down to the block level (state, county, voting district/remainder, county subdivision, place/remainder, census tract, block group, block). The file contains four tables: (1) a count of all persons by race (Table PL1), (2) a count of Hispanic or Latino and a count of not Hispanic or Latino by race of all persons (Table PL2), (3) a count of the population 18 years and older by race (Table PL3), and (4) a count of Hispanic or Latino and a count of not Hispanic or Latino by race for the population 18 years and older (Table PL4).

Scope of Study

Subject Terms:   census divisions, congressional districts, Hispanic origins, population, race, redistricting, states (USA)

Geographic Coverage:   United States

Time Period:  

  • 2000

Date of Collection:  

  • 2000

Universe:   All persons and housing units in the United States in 2000.

Data Types:   census/enumeration data

Data Collection Notes:

(1) The data are provided in three segments (files). These segments are the Geographic Header, Tables PL1 and PL2, and Tables PL3 and PL4. The Geographic Header segments are fixed-format ASCII text files, while the Table segments are comma-delimited ASCII files. The Geographic Header has 80 variables and the Table segments have 149 variables each, for a total of 378 variables when the segments are combined. (2) The SAS Merge Program is provided, but not supported, by the United States Census Bureau. Users will need to merge the three segments into a SAS dataset to use the data effectively. (3) The codebook and record layout are provided by the principal investigator as Portable Document Format (PDF) files. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader. Information on how to obtain a copy of the Acrobat Reader is provided on the ICPSR Web site.

Methodology

Data Source:

self-enumerated questionnaires

Extent of Processing:  ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Created variable labels and/or value labels.
