Home page image TIGERweb Overview

TIGERweb is a web-based system that allows users to visualize our TIGER(Topologically Integrated Geographic Encoding and Referencing database) data in several ways:

The applications allow users to select features and view their attributes, to search for features by name or geocode, and to identify features by selecting them from a map. The TIGERweb and TIGERweb Decennial applications provide a simple way to view our TIGER data without Geographic Information System(GIS) software and without downloading data. The applications use our TIGERweb REST Services.

The TIGERweb WMS and TIGERweb REST Services allow users to integrate our data into their own GIS or custom web-based applications.

  • NEW Data: Boundary and Annexation Survey (BAS 2015) Data is now available.

This Release

The TIGERweb application contains the latest version of the geographic extent of legally defined geographic areas as reported, generally reflecting the boundaries of governmental units in effect as of January 1, 2014, or legal and statistical area boundaries that have been adjusted and/or corrected since the 2010 Census. Physical features such as hydrography, transportation, and special land use areas reflect data updates as of September 2014.

This vintage enables users to see the most current boundaries of governmental units that match the data from the surveys that use 2014 geography, such as the Boundary and Annexation Survey (BAS 2015)* and the American Community Survy (ACS 2014).

In addition to the January 1, 2014 vintage (BAS 2015, ACS 2014), the TIGERweb application also contains data as of January 1, 2013 (ACS 2013) and data as of January 1, 2010 (2010 Census).

TIGERweb Decennial contains both 2010 Census geography (data as of January 1, 2010) and Census 2000 (data as of January 1, 2000) geography that has been adjusted and/or corrected since Census 2000.

*Because the Boundary and Annexation Survey (BAS) was suspended for 2014, only a minimal number of updates to governmental unit boundaries have been made since 2013.
