Description: Societal databases associated with GIS systems are as much a product of computerization as the GIS systems themselves. The U.S. census, which is the foundation of all geographically-referenced demographic and socioeconomic data, has been conducted every ten years since 1790. However, the data gathered by the census are so voluminous
that they did not become available to the public, except in very broad national and state summaries, until the advent of computers.
