Entry ID: CIESIN_SEDAC_GEOCORR
Abstract: Geographic Correspondence (GeoCorr) is a web-based application for translating
(converting) data between different geographic layers from the 1990 Census
Summary Tape Files and the Master Area Block Level Equivalency (MABLE)
database. Specific geographic layers are selected and custom "correlation
lists" are generated showing the relationship between different geographies.
For example, how ZIP ... codes correspond to counties, or how census tracts relate
to ZIP codes. It can also be used as a tool for looking at a single geographic
layer, for example, generating a listing of ZIP codes with population counts.
The application can also use x-y coordinates for filtering the data and
determining population living within a specified radius of a given location.
Output is available as both tabular and comma-separated value (.csv) files.
GeoCorr provides access to all geographic units in the 1990 Census Summary Tape
Files as well as several other layers in the MABLE database. These include:
Standard census geographies (e.g., state, county, census tract, and place, plus
1980 county, place and tract), Congressional Districts (102nd and 103rd),
5-digit ZIP codes (circa 7/91), 1990 Public Use Microdata Areas (1% and 5%
samples), Metropolitan Statistical Areas (MSAs), Hydrologic Unit Codes
(watersheds), Labor Market Areas and Commuting Zones.
MABLE is a database developed by SEDAC in collaboration with the Office of
Social and Economic Data Analysis (OSEDA) at the University of
GeoCorr is produced by the Columbia University Center for International Earth
Science Information Network (CIESIN).
The purpose is to provide data conversion, viewing, and analysis of 1990 U.S.
