Introduction
The New York State Data Center's Geography and Mapping site provides interactive query access to geographic boundary files, Census attribute data for various levels of statistical and political geography, and predefined thematic maps illustrating various economic and demographic characteristics of the population.

For the GIS user: we provide boundary files for all Census statistical geographies, state governmental units and legislative districts in MapInfo, ESRI, and Maptitude formats. Statewide files are available as well as individual counties. The map projection is the standard latitude and longitude. ERSI users can use WGS1984 for their projection.

For data analysts: we provide a large collection of 2000 Census attribute data for the same geographies as the boundary files including identification code keys for linking in GIS.

For data presentation: we have a growing collection of geographic reference and thematic maps of New York by county.

Please note: Some of these files, such as the statewide block level boundaries and attributes, are very large and are impractical for download. If you need these files you can request them on CD-ROM by choosing the "request" button. 

Also, not all geographic types or attribute types are available for all locations. For example:
    the county geographic type is not available for an individual county;
    the county sub-division type is not available for New York City; and
    Congressional, State Assembly and State Senate files are available as statewide geographic files only.
