Vitality score

Vitality score 27.6/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 37 % of the 16,267 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.

Climate

An average of 13 days a year at or above 30 °C and 37 days at or below 0 °C, over 20 complete years in 1995–2024. ^[10]

Measured at the CHOUILLY weather station, 4.5 km away at 172 m; the village itself is at 105 m. ^[10]

The village sits 67 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. ^[10]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. ^[10]

Humidity measured at CHOUILLY, 4.5 km away at 172 m, over 20 summers. ^[10]

That station sits 67 m above the village, so each day's humidity was shifted by 3.63 °C per km before the muggy days were counted. ^[10]

An average of 681 mm of rain a year, spread over 116 days — about 5.9 mm on a day it rains. ^[10]

Rainfall measured at CHOUILLY, 4.5 km away at 172 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[10]

What property sold for

37 houses sold between 2021 and 2025, at a median of 222,000 € — 1,579 € per m² of built surface. ^[11]

The median across Marne is 1,798 € per m², so this commune sits below it. ^[11]

These are recorded sale prices, not valuations or asking prices, and a median over five years spans five different markets. Built surface excludes land, which carries much of a rural property's value.
