City: U.S. Census Bureau, American Community Survey 2023 5-year estimates, table S2801 (San Francisco city, California, 362,650 households). State: 2023 1-year estimates. US: household-weighted average of the states.

Reading the San Francisco numbers

In San Francisco itself, 82.4% of households subscribe to a wired connection, 3.3 points above the statewide 79.1%. Among the 13 California cities on this site, San Francisco ranks 5th for its wired share. The number says how many homes have a line, not how many could get one: most city addresses can get at least two types.

With a wired share that high, San Francisco addresses rarely have to settle for wireless. Compare the cable plan against fiber if both are on your street; the fiber page explains why the upload speed matters more than it looks.

Satellite is rare in San Francisco at 4.1% of households, while 8.2% get online only through a phone plan and 7.6% have no subscription. The low-income help guide covers the federal Lifeline discount for homes where price is the barrier.

The rest of the picture: 4.1% of San Francisco households use satellite (4.1 points below the California figure of 8.2%) and 7.6% have no internet subscription at all. Those 27,561 unconnected homes are the group most likely to benefit from a plan check and from the federal Lifeline discount.
