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 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.

  • Application Information: The "Current" vintage reflects planned 2020 geographies for several statistical areas. See the Home tab "This Release" section for details.
  • NEW Data: January 1, 2019 (BAS 2020) data is now available.
  • NEW Application: TIGERweb now provides a 2017 Economic Census Application.

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, 2019 or legal and certain statistical area boundaries (census regions and divisions, metropolitan and micropolitan statistical areas, public use microdata areas, urban areas, ZIP Code tabulation areas) that have been adjusted and/or corrected since the 2010 Census.

The "Current" vintage reflects planned 2020 geographies for census tracts, census block groups, census designated places (CDPs), census county divisions (CCDs), tribal census tracts, tribal block groups, Alaska Native village statistical areas (ANVSAs), Oklahoma tribal statistical areas (OTSAs) and their tribal subdivisions, state American Indian Reservations (SAIRs), state designated tribal statistical areas (SDTSAs), and tribal designated statistical areas (TDSAs) as collected through the 2020 Participant Statistical Areas Program (PSAP). PSAP participants are reviewing and verifying these areas, and identifying corrections where needed, before they are used in the tabulation and publication of data.

ACS data users should use the appropriate ACSyy vintage for statistical area boundaries relating to ACS estimates.
