Boston and Suffolk County
Boston is associated with Suffolk County in the Census boundary data. Start with the parcel’s tax bill to match the property to that jurisdiction, then confirm which government handles its land use.
Boston by land and water
The Census records 41.3 square miles of water within Boston, or 46.1% of its total area. It is 5.5 percentage points lower than the 51.5% recorded for Suffolk County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Boston city has 24.2 times the land area of nearby Winthrop Town city (1.99 square miles). These areas describe boundaries, not comparable property prices.
