Vitality score

Vitality score 29.2/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 84 % of the 16,607 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 11 days a year at or above 30 °C and 94 days at or below 0 °C, over 26 complete years in 1995–2024. ^[12]

Measured at the COGNA weather station, 7.1 km away at 577 m; the village itself is at 774 m. ^[12]

The village sits 197 m above the station, so each day's reading was shifted by 5.55 °C per km of altitude before the days were counted. Expect the result to be within about 0.68 °C. ^[12]

Muggy days — a dew point at or above 18 °C — average 0 days a summer. ^[12]

Humidity measured at ST LAURENT - SA, 7.8 km away at 880 m, over 10 summers. ^[12]

That station sits 106 m above the village, so each day's humidity was shifted by 3.06 °C per km before the muggy days were counted. ^[12]

An average of 1,786 mm of rain a year, spread over 150 days — about 11.9 mm on a day it rains. ^[12]

Rainfall measured at LE FRASNOIS, 4.9 km away at 773 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]

What property sold for

19 houses sold between 2021 and 2025, at a median of 155,000 € — 1,310 € per m² of built surface. ^[13]

7 flats sold over the same window, at a median of 118,750 € — 1,838 € per m². ^[13]

The median across Jura is 1,428 € per m², so this commune sits about level with it. ^[13]

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.
