What Does The Name TIGER® mean?

The term TIGER® comes from the acronym Topologically Integrated Geographic Encoding and Referencing which is the name for the system and digital database developed at the Census Bureau to support its mapping needs for the Decennial Census and other Bureau programs.

What Is TIGER®?

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 and manipulate TIGER/Line data. These data files are not provided 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.

Why is the TIGER® data so valuable?

The TIGER® data is used in address geocoding operations. Each street segment stored in the data set is attributed with ranges of house numbers. With the proper software, textual address information can be accurately located within the TIGER® street data. Most popular GIS software packages will accept this data and perform address geocoding with user supplied address lists.

This six-CDROM set of feature data for the entire United States, costs a mere $130 (US) including shipping and handling.
