Description: This dataset is a TIGER/Line Shapefile product from the U.S. Census Bureau including jurisdictions which make up the Transportation Planning Board (TPB) Members. 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.

Description: The boundary feature classes were developed using multiple sources to produce the most relevant boundary layers for COG/TPB. Generally, county and county equivalent jurisdictions use the 2020 Census County level TIGER/Line geography. Jurisdictional data for independent cities and other COG/TPB member jurisdictions, where available, were used in place of Census data.The Census TIGER data are available at: https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.html. The TIGER/Line Shapefiles are extracts of selected geographic and cartographic information from the Census Bureau's Master Address File (MAF)/Topologically Integrated Geographic Encoding and Referencing (TIGER) system. Although it doesn't include any demographic information, the TIGER/Line Shapefiles contain a standard geographic identifier (GEOID) for each entity that links to the GEOID in the data from censuses and surveys which include them.
