Census of Population and Housing, 1990
User-Defined Areas Program (UDAP)
San Diego, California

DATA COLLECTION: This data collection was generated by the Census Bureau's User-Defined Areas Program (UDAP) for the City of San Diego Planning Commission. UDAP provides a set of predefined data tables for locally defined areas that do not correspond to standard 1990 census geographic areas. The San Diego Planning Department identified the geographic areas of interest to them by delineating boundaries around groupings of census blocks on 1990 census County Block Maps. All San Diego, California geographic areas are listed in the San Diego UDAP names and codes table.

The source of these data is the Census of Population and Housing Summary Tape File 3. Summary Tape File 3 (STF 3) contains sample data weighted to represent the total population. In addition, the file contains 100-percent counts and unweighted sample counts for total persons and total housing units. Additional population and housing variables include age, ancestry, disability, citizenship, education, income, marital status, race, sex, travel time to work, rent, tenure, value of housing unit, number of vehicles, and monthly owner costs. All population and housing items are listed in the San Diego UDAP Data Dictionary.

The SSDC staff converted the Census Bureau database files into a relational database and linked the data names/codes to the detailed Census Bureau San Diego UDAP data files. Each detailed file was output in HTML, spreadsheet (.xls) and dbase IV (.dbf) formats. Each detailed file is a group of tables (variables) for all UDAP areas in San Diego, California. The database files can be imported into GIS software.
