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: May 06, 2026 at 05:49 AM | Dataset Last Updated: May 01, 2020 at 12:00 AM
This resource is a member of a series. The TIGER/Line shapefiles and related database files (.dbf) 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 shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Urban Growth Areas (UGAs) are legally defined entities in Oregon and Washington that the Census Bureau includes in the MTDB in agreement with each State. UGAs, which are defined around incorporated places, are used to regulate urban growth. UGA boundaries, which need not follow visible features, are delineated cooperatively by State and local officials in Oregon and Washington. Each UGA is identified by a 5-digit numeric census code, usually associated with the incorporated place for which the UGA is named. The UGAs for the 2020 Census were those in effect as of January 1, 2020.
