NOTE: Gray indicates insufficient data or a suppressed estimate.
Suburban zip codes west and south of Boston—particularly in the MetroWest corridor and communities along Route 128—consistently reach 90–100% broadband adoption, while several zip codes in the western Berkshires and rural hilltowns of Franklin and Hampshire counties fall noticeably lower, into the 60–80% range. Parts of the outer Cape Cod and the Islands also display lower broadband penetration compared to the mainland, likely reflecting a mix of seasonal housing stock and infrastructure limitations. Within the Greater Boston core, a few urban zip codes—potentially corresponding to lower-income neighborhoods in cities like Springfield, Worcester, and Boston proper—show measurably lower rates than their affluent suburban neighbors, highlighting a persistent digital divide along socioeconomic lines.
