Administrative Boundaries of Boston and Massachusetts

Guide to resources on wards, towns, counties, metropolitan areas etc.

Annexed Towns

Boston annexed neighboring municipalities in the late 19th and early 20th centuries.

  • 1868 - Roxbury
  • 1870 - Dorchester (including Mattapan)
  • 1874 - Brighton (including Allston), Charlestown, West Roxbury (including Jamaica Plain and Roslindale)

Neighborhoods

Neighborhoods are smaller geographic communities within which people and places are perceived as having shared social, historical, and cultural characteristics. While the city has official maps of neighborhoods, boundaries tend to be subjective. Neighborhoods do not have official or administrative purposes.

Wards

Wards are administrative divisions within a city for purposes such as voting or public services. They do not correspond to neighborhoods.
