Housing % of Units Built Since 2010, by Zip Code (ZCTA5) — Massachusetts

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the Greater Boston metro area—particularly in and around the urban core—display notably higher shares of housing built since 2010, with several zones exceeding 20-30%, reflecting the region's sustained development boom driven by demand near employment and transit hubs. Western Massachusetts and the rural interior largely fall below 4%, indicating minimal new construction activity over the past decade-plus. Cape Cod and the southeastern coastal areas present a mixed but generally low pattern, with isolated pockets of moderate growth amid predominantly older housing stock.
