Vitality score

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

Confidence: high.

Better served than 41 % of the 12,279 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 37 days at or below 0 °C, over 22 complete years in 1995–2024. ^[12]

Measured at the DERVAL weather station, 9.6 km away at 43 m; the village itself is at 24 m. ^[12]

An average of 885 mm of rain a year, spread over 125 days — about 7.1 mm on a day it rains. ^[12]

Rainfall measured at NOZAY, 5.5 km away at 44 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
