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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Broadband adoption rates across the Seattle metro area generally exceed 80%, though notable disparities emerge between the eastside suburbs and certain urban cores. Zip codes in Kirkland, Redmond, and Bellevue consistently register among the highest broadband penetration rates at 90–100%, while pockets of south Seattle, central Tacoma, and areas south of Lakewood fall noticeably lower, dipping below 75% and in some cases approaching 50%. This east-west and north-south gradient suggests that broadband access gaps align with well-documented income and demographic divides in the region, particularly along the I-5 corridor south of downtown Seattle.
