Published by U.S. Department of Commerce, U.S. Census Bureau, Geography Division, Spatial Data Collection and Products Branch | U.S. Census Bureau, Department of Commerce | Catalog Last Checked: December 19, 2025 at 01:18 PM | Dataset Last Updated: January 01, 2011 at 12:00 AM
The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Traffic analysis districts (TADs) are basic aggregates of traffic analysis zones (TAZs) created to provide a higher level geographic entity to facilitate the ability of transportation planners to forecast changes in commuting patterns, trip volumes, and modes of travel, and to develop plans to meet the changing demands for transportation facilities and capacities.
