% of Households with Broadband Internet, by Zip Code (ZCTA5) — Boston Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

Broadband adoption rates across the Boston metro area generally exceed 80%, with the highest concentrations (95–100%) clustering in suburban zip codes to the west and northwest, including areas around Waltham, Newton, and the outer ring communities. A notable pocket of lower broadband penetration (roughly 60–75%) is visible in parts of Boston proper, particularly in neighborhoods south of downtown and extending toward Quincy, suggesting a digital divide that aligns with historically lower-income urban corridors. The coastal zip codes east of Lynn and areas near Weymouth Town display moderate variability, while Somerville and Medford sit in an intermediate range between their better-connected western suburbs and the lower-adoption urban core.
