American FactFinder

American FactFinder is the Census Bureau's primary web-based dissemination vehicle for 2000 Census data and maps.

PDF Format Digital Files

"Some predefined map types, such as the County Block Map and the Census Tract Outline Map, will be available in both Hewlett-Packard Graphics Language (HP-GL/2) and Adobe's Portable Document Format (PDF). Other specialized maps, such as thematic wall maps, will be available in PDF and/or PostScript format." http://www.census.gov/geo/DR/plotter.pdf

HP-GL/2 Format Digital Files

"Some predefined map types, such as the County Block Map and the Census Tract Outline Map, will be available in both Hewlett-Packard Graphics Language (HP-GL/2) and Adobe's Portable Document Format (PDF). Other specialized maps, such as thematic wall maps, will be available in PDF and/or PostScript format. Maps in HP-GL/2 format are provided to facilitate high volume map plotting." http://www.census.gov/geo/DR/plotter.pdf

TIGER/Line Digital Files

"The TIGER/Line files are a digital database of geographic features, such as roads, railroads, rivers, lakes, political boundaries, census statistical boundaries, etc. covering the entire United States. The data base contains information about these features such as their location in latitude and longitude, the name, the type of feature, address ranges for most streets, the geographic relationship to other features, and other related information. They are the public product created from the Census Bureau's TIGER (Topologically Integrated Geographic Encoding and Referencing) data base of geographic information. TIGER was developed at the Census Bureau to support the mapping and related geographic activities required by the decennial census and sample survey programs.

"These files are not graphic images of maps, but rather digital data describing geographic features. To make use of these data, a user must have mapping or Geographic Information System (GIS) software that can import TIGER/Line data. The Census Bureau does NOT provide these data in any vendor-specific format. With the appropriate software a user can produce maps ranging in detail from a neighborhood street map to a map of the United States. To date, many local governments have used the TIGER data in applications requiring digital street maps. Software companies have created products for the personal computer that allow consumers to produce their own detailed maps. There are many other possibilities. THE TIGER/LINE PRODUCT DOES NOT INCLUDE DEMOGRAPHIC STATISTICS." http://www.census.gov/geo/www/tiger/overview.html
