Welcome to

Introduction.

The Demography HomePage is part of an initiative to identify, document, and provide simple access to demographic information concerning The United States of America. This part describes CIESIN's data holdings and related information. This HomePage consists of a series of cascading hypertext links providing access to national data resources, on-line supporting documentation (codebooks, data dictionaries, citations), and possibly extraction tools for data access, and you may connect to an anonymous ftp service for data file retrieval.

The information contained on this page is organized by major data resource. The source documents will be indexed, allowing for full and/or paragraph text searches. In addition, this page also provides connectivity to many world wide web and gophers sites listed and grouped in four distinct lists. By clicking on the highlighted (or underlined) sites you can connect to those services listed directly.

Clicking on this symbol [ ] will reveal the primary information sources for the current viewing page. Finally, at the bottom of this home-page, "buttons" are provided for the users's convenience, for example; button #2 connects directly to CIESIN's Home Page "Information for a Changing World", or try button #1, CIESIN's navigational tool.

Data Extraction Services

CIESIN Data Exploration Software

The CIESIN Data Exploration Software provides interactive browsing and analysis of the Public Use Microsample (PUMS) data sets from the U.S. 1980 and 1990 census, allowing users to analyse more than 2.6 million records in each data set. CIESIN Data Exploration Software is currently in beta testing.

BUREAU OF THE CENSUS

The Bureau has a "Data Extraction System" (DES) which can be reached via a telnet session (login as user "desuser", press the return key when prompted for a password). On-line, and accessible for extraction, are :

• 1990 SIPP (Survey of Income and Program Participation), and
• 1991 SIPP (Survey of Income and Program Participation), and
• 1992 CPS (Current Popualtion Survey).

To learn more about this service read the document "About SIPP".

CENSUS DATA AT LAWRENCE BERKELEY LABORATORY

Nationwide data from the 1970, 1980, and 1990 U.S. Censuses are available at Lawrence Berkeley Laboratory (LBL). The LBL data archive is believed to be the most complete collection of Census data on the Internet.

To learn more about this service connect to Lawrence Berkeley Labs.

Simulations and Modeling

• HumPop. HumPop is a multimedia tutorial program. HumPop introduces and illustrates population concepts and issues (Project GeoSim, Depts of Geography and Computer Science, Virginia Tech).

Innovative Approaches

• Chicago Community Area Demographics. An innovative way of presenting STF3A data via maps and lists is presented by the University of Illinois at Chicago, Department of Electrical Engineering and Computer Science and the Department of Geograpghy.

• 1990 Census Lookup (data retrieval)

  LOOKUP is an experimental WWW server for retrieving data from the following 1990 Census Summary Tape Files. A WWW client with forms capability is required.

     STF1A STF1C STF1D 
     STF3A STF3C STF3D
  
     LOOKUP makes use of CD-ROMs in Berkeley, California.
