Decennial Census Information: 1990 Census CD-ROMs
The Census Bureau released a large portion of the 1990 Census on CD-ROM as well as on computer tape. The Columbia Electronic Data Service (EDS), located in Room 201 of Lehman Library, has all CD-ROM products released by the Census Bureau and tape of other Census materials pertinent to the New York area. The CD-ROMs were created from the original computer tapes and have made access to census data easier than ever before. Data can be browsed using Go, a menu-driven software developed by the Census Bureau, or special subsets of data can be created using Extract, a more complex software.
Volumes which contain tables specifically about New York City and State are highlighted.
The 100% population data include the CP-1 (General Population Characteristics) and the CH-1 (General Housing Characteristics). There are two sets of machine readable formats: the PL 94-171 data summarizing all questions down to the tract level--for the purposes of reapportionment--and the Summary Tape Files 1 and 2, which provide comparative summaries for the 100% population counts.
The sample data include CP-2 (Social and Economic Characteristics) and CH-2 (Detailed Housing Characteristics). There are two sets of machine readable formats: the Summary Tape Files 3 and 4, which provide statistics for the samples of the population, and the Public Use Microdata Series (PUMS) which consist of the actual sample data with most geographical identifiers removed. The 1990 Census has released three PUMS versions--the full 5% (1 in 20) sample (consuming about 25 reels of computer tape or 7 CD/ROM disks), a (1 in 100) 1% sample (about 5 reels of computer tape or 2 CD/ROM disks), and a .1% (1 in 1,000) sample (one tape).
