  skos:definition """Demographic Data Viewer (DDVIEWER) is a web-based application providing rapid data mapping, viewing, and analysis of more than 200 U.S. census-derived socioeconomic variables for geographic levels ranging from states to census block groups. A useful tool for browsing and visualizing population patterns, DDVIEWER is offered in Java and non-Java versions, each offering ... slightly different features. The core data processed are a collection of more than 200 variables from the 1990 U.S. Census Summary Tape File (STF)3A. These data cover various subjects including: general population; persons by race and age; households by size, type and income; families by number of workers; other income measures; level of education; unemployment; occupation; housing units, age and value. The distribution of values for these variables can be displayed for various census geographic units including: U.S. states, counties, county subdivisions, census tracts, and blockgroups. Map and attribute data output are available in a variety of formats.

DDViewer is produced by the Columbia University Center for International Earth Science Information Network (CIESIN).
