Description: In Massachusetts, cities and towns are recognized and recorded as “county subdivisions” by the Census Bureau. County subdivisions are the primary divisions of counties and their equivalent entities for the reporting of decennial census data. A 5-character FIPS code (recorded in COUSUBFP) is used to uniquely identify each county subdivision. Census towns have linework that is often identical to the linework found in MassGIS' munipality boundaries, but also contains many minor discrepancies, particularly along hydrologic and coastal features. The annual Boundary and Annexation Survey (BAS) program attempts to reconcile significant differences in linework (typically discrepancies of 30 feet or more) between Census county subdivisions and the authoritative record, especially where populations are involved. Census towns have been processed and made available to provide a city and town reference for mapping that should align better than the MassGIS municipality boundaries with other Census-derived geographies, including voting districts. The Municipal Boundaries from Census 2020 line feature class was created by dissolving the Census 2020 data on the COUSUBFP10 (county subdivision) field and converting that polygon dataset (CENSUS2020TOWNS_POLY) to a line dataset. The linework in layer was then coded to distinguish state boundaries, municipal boundaries and coastline This dataset may be used as basemap data when mapping Census 2020 geography, as other municipal boundary layers from MassGIS will not line up exactly with the Census geography.
