Methodology
Figures cover contracts procured by buyers in St. Gallen (not where work is performed), derived from SIMAP and archive award records. Data through 2026-06-30. Awards whose procuring canton cannot be resolved (a small share of gazette-only records) are excluded from per-canton totals, so figures are a floor.
Modules below a reliability threshold are omitted rather than shown thin. Updated monthly.
