Vitality score

Vitality score 35.3/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 43 % of the 13,287 communes of a similar size.

Compare this with communes of a similar size. The score measures how well a place is served relative to its own size band, and larger communes score higher as a rule — so it reads meaningfully against another village, and misleadingly against a town.

6 flats sold over the same window, at a median of 123,500 € — 1,734 € per m². ^[12]
