Resource Abstract:
- description: The TIGER/Line shapefiles and related database files (.dbf) (NTAD) 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. After each decennial census, the Census Bureau delineates urban areas that represent densely developed
territory, encompassing residential, commercial, and other nonresidential urban land uses. In general, this territory consists
of areas of high population density and urban land use resulting in a representation of the "urban footprint." There
are two types of urban areas: urbanized areas (UAs) that contain 50,000 or more people and urban clusters (UCs) that contain
at least 2,500 people, but fewer than 50,000 people (except in the U.S. Virgin Islands and Guam which each contain urban clusters
with populations greater than 50,000). Each urban area is identified by a 5-character numeric census code that may contain
leading zeroes.; abstract: The TIGER/Line shapefiles and related database files (.dbf) (NTAD) are an extract of selected geographic
