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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Broadband internet adoption in the Baltimore metro area exhibits a clear core-periphery disparity, with several zip codes in inner Baltimore City—particularly in the west and northwest sections—falling below 60%, while surrounding suburban areas in Howard County near Columbia and Ellicott City consistently reach 90% or higher. The northeastern and northwestern outer suburbs display uniformly high adoption rates in the 85–95% range, whereas pockets of lower connectivity persist in zip codes immediately surrounding downtown Baltimore and extending southward toward the harbor. This spatial pattern closely mirrors well-documented income and demographic gradients in the region, with the starkest contrasts occurring within just a few miles of the city center.
