Vitality score

Vitality score 34.6/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 35 % of the 12,283 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.

…and in much the same climate

The same match on size and services, narrowed to communes whose summers, winters and summer humidity are all close to Sainte-Gemme's. All three are required, so this section is absent for the 11.8 % of communes with no humidity station near enough to measure: two temperature axes alone cannot tell a muggy coast from a dry one.
