History of the state data census center

The State Data Center Program was established in 1978 to create a lead agency in each state to act as the chief source of census data in both print and machine-readable formats. Acting through a network of affiliate state agencies, universities, libraries, and regional and local governments, SDC has become one of the Census Bureau's most successful partners in making census information available to the public.

Since its inception, SDC has worked diligently to incorporate state of the art technology into how the public receives and accesses census data. Significant changes in data collection, dissemination, and analysis, pioneered by the Census Bureau, have been incorporated into the operation of its state networks.

Initially State Data Centers were the primary points for public access to census data. Much of the data from the 1980 Census was available only in machine-readable formats and released to the data centers via tape and microfiche without a specific request, on a first, free, and automatic basis. Centers were then able to process large census files and create value-added products that gavelocal governments and general data users better access to census information. In the 1990s, CD-ROM technology eliminated the need to process tapes and data became more readily available on the Internet. Even with greater public access, there remains the need to advise and train data users on the appropriate use and interpretation of data. Data centers have the specialized expertise required to assist users with processing data and have successfully expanded the capabilities of the Census Bureau to respond to public inquiries.
