Vitality score

Vitality score 55.5/100 — Partly served (model fr-v0.2).

Confidence: high.

Better served than 85 % of the 9,609 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.

Measured at the LA COTE ST ANDRE weather station, 15.3 km away at 346 m; the village itself is at 456 m. ^[11]

The village sits 110 m above the station, so each day's reading was shifted by 6.06 °C per km of altitude before the days were counted. Expect the result to be within about 0.68 °C. ^[11]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. ^[11]

Humidity measured at BOURGOIN, 15.8 km away at 358 m, over 20 summers. ^[11]

That station sits 98 m below the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[11]

An average of 925 mm of rain a year, spread over 106 days — about 8.7 mm on a day it rains. ^[11]

Rainfall measured at ST-JEAN-DE-BOURNAY, 5.4 km away at 369 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
