Monthly boardings on King County Metro buses and trolleybuses, from the National Transit Database, through July 2026: a 2020 collapse and a partial recovery to 7,757,126 against a peak of 11,328,648 in October 2019.

King County Metro carried 7,757,126 bus boardings in July 2026, up 0.2% on the year. The peak in this series is 11,328,648 (October 2019), which puts the latest month 32% below it.

The bus is the part of the transit system that mostly does not get written about, and it carries far more people than the train does. It is also the better economic indicator of the two: the bus network has not changed shape the way the rail network has, so its ridership moves with commuting, employment and the cost of driving rather than with construction schedules. The gap between the bus line and the rail line since 2020 is the clearest picture available of how office work changed in this region.

Trolleybus routes are included with the diesel and hybrid fleet — they are one network to a rider and splitting them would chart the vehicle procurement rather than the travel. Boardings, not journeys: a trip with a transfer counts twice. Not seasonally adjusted, so compare with the same month a year earlier.
