Vitality score

Vitality score 41.2/100 — Partly served (model fr-v0.2).

Confidence: high.

Better served than 93 % of the 17,839 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.
