Census of Population and Housing, 2000 [United States]: 1998 Dress Rehearsal, P.L. 94-171 Redistricting Data, Geographic Files for 11 Counties in South Carolina, Sacramento, California, and Menominee County, Wisconsin (ICPSR 2913)
The 1998 Dress Rehearsal was conducted as a prelude to the United States Census of Population and Housing, 2000, in the following locations: (1) Columbia, South Carolina, and surrounding areas, including the town of Irmo and the counties of Chester, Chesterfield, Darlington, Fairfield, Kershaw, Lancaster, Lee, Marlboro, Newberry, Richland, and Union, (2) Sacramento, California, and (3) Menominee County, Wisconsin, including the Menominee American Indian Reservation. This collection contains map files showing various levels of geography (in the form of Census Tract Outline Maps, Voting District/State Legislative District Outline Maps, and County Block Maps), TIGER/Line digital files, and Corner Point files for the Census 2000 Dress Rehearsal sites. The Corner Point data files contain the bounding latitude and longitude coordinates for each individual map sheet of the 1998 Dress Rehearsal Public Law (P.L.) 94-171 map products. These files include a sheet identifier, minimum and maximum longitude, minimum and maximum latitude, and the map scale (integer value) for each map sheet. The latitude and longitude coordinates are in decimal degrees and expressed as integer values with six implied decimal places. There is a separate Corner Point File for each of the three map types: County Block Map, Census Tract Outline Map, and Voting District/State Legislative District Outline Map. Each of the three map file types is provided in two formats: Portable Document Format (PDF), for viewing, and Hewlett-Packard Graphics Language (HP-GL) format, for plotting. The County Block Maps show the greatest detail and the most complete set of geographic information of all the maps. These large-scale maps depict the smallest geographic entities for which the Census Bureau presents data -- the census blocks -- by displaying the features that delineate them and the numbers that identify them. These maps show the boundaries, names, and codes for American Indian/Alaska Native areas, county subdivisions, places, census tracts, and, for this series, the geographic entities that the states delineated in Phase 2, Voting District Project, of the Redistricting Data Program. The HP-GL version of the County Block Maps is broken down into index maps and map sheets. The map sheets cover a small area, and the index maps are composed of multiple map sheets, showing the entire area. The intent of the County Block Map series is to provide a map for each county on the smallest possible number of map sheets at the maximum practical scale, dependent on the area size of the county and the density of the block pattern. The latter affects the display of block numbers and feature identifiers. The Census Tract Outline Maps show the boundaries and numbers of census tracts, and name the features underlying the boundaries. These maps also show the boundaries and names of counties, county subdivisions, and places. They identify census tracts in relation to governmental unit boundaries. The mapping unit is the county. These large-format maps are produced to support the P.L. 94-171 program and all other 1998 Dress Rehearsal data tabulations. The Voting District/State Legislative District Outline Maps show the boundaries and codes for voting districts as delineated by the states in Phase 2, Voting District Project, of the Redistricting Data Program. The features underlying the voting district boundaries are shown, as well as the names of these features. Additionally, for states that submit the information, these maps show the boundaries and codes for state legislative districts and their underlying features. These maps also show the boundaries of and names of American Indian/Alaska Native areas, counties, county subdivisions, and places. The scale of the district maps is optimized to keep the number of map sheets for each area to a minimum, but the scale and number of map sheets will vary by the area size of the county and the voting districts and state legislative districts delineated by the states. The Census 2000 Dress Rehearsal TIGER/Line Files consist of line segments representing physical features and governmental and statistical boundaries. The files contain information distributed over a series of record types for the spatial objects of a county. These TIGER/Line Files are an extract of selected geographic and cartographic information from the Census TIGER (Topologically Integrated Geographic Encoding and Referencing) database. While the geographic coverage for a single TIGER/Line File is usually a county or statistical equivalent entity, the 1998 Dress Rehearsal TIGER/Line Files include only those entities included in the Dress Rehearsal with the coverage area based on January 1, 1998, legal boundaries. The Census's TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each 1998 Dress Rehearsal TIGER/Line File is designed to stand alone as an independent dataset. The TIGER/Line Files for each distinct geographic area can also be combined to show the entire area that was included in the Dress Rehearsal for that site. There are a total of 17 record types in the TIGER/Line Files, including the basic data record, the shape coordinate points, and geographic codes, that can be used with appropriate software to prepare maps. A complete list of codes for the record types can be found in Chapter 6 of the Technical Documentation for TIGER/Line Files (Part 603).

Scope of Study
Subject Terms: census data, census methods, census tract level, computer aided mapping, congressional districts, counties, election districts, ethnicity, geographic information systems, household composition, housing, housing conditions, legislative districts, population, redistricting, states (USA)
The maps for plotting are provided as Hewlett-Packard Graphics Language (HP-GL) files. The Census maps in HP-GL format are designed for output on the HP DesignJet 1050C. The Census Bureau does not endorse the use of a particular manufacturer's product for plotting maps. The recommended configuration and general hardware specifications for an output device capable of plotting the map products are as follows: media size: 36-inch wide roll, resolution: 600 dpi, color and black and white, memory: 80 megabytes RAM, 2-gigabyte hard disk, language: HP-GL/2. It is recommended that the HP-GL files are plotted directly from Unix, MS-DOS, or software applications distributed by the Census Bureau. Plotting the files from within other applications is not recommended.
There are no Voting District/State Legislative District Outline Maps for Menominee County, Wisconsin, in this data collection.
Census 2000 Dress Rehearsal data recorded with a variety of encoding techniques, such as automated map scanning, manual map digitizing, standard data keying, and computer file matching
