Precinct turnout

King County publishes precinct-level election results as queryable tables. Every row carries Registered Voters and Times Counted, so turnout by precinct, legislative district, county-council district or congressional district is a query — not a public-records request. Pick an election and a race. Everything below runs in your browser against the county's own files.

Nothing is sent to or stored by the Dispatch — the prompt is assembled in your browser and goes wherever you paste it. It carries the figures verbatim and tells your AI to work only from them and to say so rather than estimate when a question needs data that isn't there.

Before you use these numbers

Registered-voter denominators move. Registration is measured as of the election, so comparing turnout across years compares against different denominators. Say which election.
Precinct boundaries are redrawn. Precinct IDs are not stable across redistricting, so a precinct-level time series needs the historical boundaries, not just the IDs.
Times Counted is ballots returned, not votes in this race. A voter who returned a ballot but skipped this contest is still inside it, recorded separately as an under-vote — so turnout does not sag on a quiet down-ballot race. In the August 2026 primary, Times Counted is identical across every race in a given precinct. The exception is a precinct split by a jurisdiction boundary, where a race covering only part of it reports a slightly different total: comparing a Seattle-only measure against a countywide race, 184 of 1,020 precincts differ, by at most 4 ballots, and 232 of 212,419 ballots overall.
Small precincts are noisy. The spread table below hides precincts under 100 registered voters for that reason.
Use the Final results. King County publishes an election-night count and, for recent elections, a mid-election update before the Final one. Only Final results are listed here; anything citing election-night counts in a vote-by-mail county is citing a partial tally.
The asset that comes up first in a search is a trap. gj9e-v6eq, "King County Voter Turnout by Precinct," is a map, not a table — its API answers "no row or column access to non-tabular tables" and it only covers 2010 through 2019. This page never touches it.
