Vitality score

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

Confidence: medium (sources disagree on Restaurant).

Better served than 61 % of the 13,561 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.

Measured but not scored in this model: Market. See the methodology for why.
