What this data can and can’t tell you

  • Mayors and councilors. From the Interior ministry’s national register of elected officials (RNE) as published on August 11, 2026: name, office and start dates, nothing else. The register counts a mayor as a councilor too; the page counts each person once. It isn’t a live roll: resignations and replacements after that date aren’t shown, and no party is inferred for any official.
  • How the council is elected. Since March 2026 every commune elects its council from lists (a 2025 law extended list voting to communes under 1,000). A list with more than half the votes in the first round wins; otherwise lists with 10% or more can go on to a second round, where the list ahead wins. It gets half the seats, and the rest are shared in proportion among lists with 5% or more. The council then elects the mayor and the deputy mayors.
  • The label beside a list. The political nuance the prefecture gave the list for the ministry’s results (Divers droite, Union de la gauche…), shown as published. It isn’t the list’s own description; many lists, most in small communes, have none.
  • The commune’s money. OFGL’s consolidated accounts from the DGFiP, 2018 to 2025; 2025 is provisional. Spending and investment leave out loan repayments; running costs are part of spending. Debt is what was owed at the end of the year.
  • Per resident. Divided by the DGFiP’s population for that year (population totale, which counts some people, such as boarding students, in two communes), so it can differ from the census figure elsewhere on the site.
  • The medians. Beside the town’s figure, the median of compared communes in its département and in France (those with an overall grade). A commune’s spending follows its size and its role: one that runs a pool or a theater for the villages around it spends more per resident.
