Vitality score

Vitality score 45.8/100 — Partly served (model fr-v0.2).

Confidence: high.

Better served than 90 % of the 17,510 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 BOUZY-CIVC weather station, 9.5 km away at 153 m; the village itself is at 77 m. ^[13]

The village sits 76 m below the station, so each day's reading was shifted by 5.89 °C per km of altitude before the days were counted. Expect the result to be within about 0.68 °C. ^[13]

Muggy days — a dew point at or above 18 °C — average 2 days a summer. ^[13]

Humidity measured at BOUZY-CIVC, 9.5 km away at 153 m, over 21 summers. ^[13]

That station sits 76 m above the village, so each day's humidity was shifted by 3.63 °C per km before the muggy days were counted. ^[13]

An average of 682 mm of rain a year, spread over 118 days — about 5.8 mm on a day it rains. ^[13]

Rainfall measured at THIBIE, 8.9 km away at 97 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[13]
