- Coverage
- Geography cantons (26; Jura from 1979) · from 1848-09-12 · to 2026-09-27
- Gaps
- Cantonal yes shares and turnout are empty in swissvotes for the votes since 9 June 2024 (anr 667 onwards on 2026-10-31); for those votes the dataset has the cantonal majorities only. The BFS publishes them in its open data "Echtzeitdaten am Abstimmungstag"; they are fetched as bfs-vote-results (from 2024-03-03), which the canton pages use where this dataset has no share. Turnout is not available for the 19th-century votes, yes shares are not available for vote 1 (1848). Vote counts (yes, no, valid, entitled to vote) stay in the raw dataset.

- AGORA-22, STORY-09
- Known limits
- swissvotes compiles the cantonal results from the BFS (STAT-TAB). Three published shares do not match the published majority at one decimal (anr 126.2 NE 48.37 % with a yes majority, anr 311.1 GR 49.98 % with a yes majority, anr 615 BE 50.00 % with a yes majority); values are kept as published. Before 1979 the canton of Bern includes today's canton of Jura; before 2026 Moutier votes in Bern. From 1874 the cantonal popular majority is the canton's vote for the majority of the cantons (codebook); half cantons count half there.

Transformations
- Download the semicolon-separated UTF-8 CSV (BOM, CRLF), parse it with the hand-rolled RFC 4180 parser and read, for each of the 26 cantons, the codebook variables <canton>-japroz, <canton>-bet and <canton>-annahme (codebook pp. 36–37). Script: scripts/fetch/swissvotes-cantons.ts
- canton = abbreviation in upper case (ZH … JU), in BFS order; anr copied as published (join with the swissvotes entry for date, titles, type and national result).
- yes_pct = <canton>-japroz (share of yes votes in the valid ballots, %) and turnout = <canton>-bet (%), rounded half-up from two to one decimal like the national yes_pct; "." or empty becomes empty. For tie-breakers yes_pct is the share preferring the popular initiative (codebook).
- majority = <canton>-annahme: 0 no, 1 yes, 8 prefer_counter, 9 prefer_initiative (tie-breakers); "." becomes empty. Any other code fails the fetch.
- A row is written for each vote and canton with at least one value; scheduled votes (no result yet) and Jura before 1979 have none and are left out. Rows sorted by vote number, then canton.
