Vitality score

Vitality score 37.4/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 55 % of the 14,330 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.

An average of 12 days a year at or above 30 °C and 52 days at or below 0 °C, over 28 complete years in 1995–2024. ^[11]

Humidity measured at ORCEMONT, 5.5 km away at 164 m, over 11 summers. ^[11]

An average of 688 mm of rain a year, spread over 117 days — about 5.9 mm on a day it rains. ^[11]

…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 Saint-Hilarion'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.
