Where competition is thinnest — the share of awards that drew a single bid (no competing offer), by industry and by municipality.
Single-bid share = awards with exactly one bid ÷ awards that have bid data.
Single-bid share = awards with exactly one bid ÷ awards that have bid data.
Share of each sector's awarded spend going to its single largest supplier (Top 1) and its top three (Top 3). Higher = more dominated by a few firms.
Authorities (with 3+ suppliers) sending the largest share of their spend to a single (Top 1) or top-three (Top 3) supplier.
Single-bid share by procurement procedure. Simplified procedures — minimum-value and limited — draw far less competition than open tenders.
Average bidders per tender by sector — competition runs deepest in construction and thinnest in fuel. The single-bid share is shown for context.
Share of each supplier's public revenue that comes from its single biggest buyer. Near 100% means the firm sells almost exclusively to one institution — a capture signal.
Pairs of firms that repeatedly bid on the same tenders, where one wins almost every time and the other almost never does. The score is wins when the two bid together. This is a prompt for a closer look — co-bidding can simply mean two firms share a market niche, and it is not proof of any wrongdoing.
