Vitality score

Vitality score 36.7/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 37 % of the 11,425 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.

The median across Charente-Maritime is 2,339 € per m², so this commune sits below it. ^[13]

These are recorded sale prices, not valuations or asking prices, and a median over five years spans five different markets. Built surface excludes land, which carries much of a rural property's value.
