Vitality score
Vitality score 29/100 — Few services (model fr-v0.2).
Confidence: high.
Better served than 72 % of the 17,908 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
Where this sits nationally
An average of 24 days a year at or above 30 °C and 96 days at or below 0 °C, over 13 complete years in 1995–2024. [10]
Measured at the MENS weather station, 4.2 km away at 780 m; the village itself is at 821 m. [10]
Muggy days — a dew point at or above 18 °C — average 0 days a summer. [10]
Humidity measured at LA MURE- RADOME, 9.3 km away at 885 m, over 21 summers. [10]
That station sits 64 m above the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. [10]
An average of 857 mm of rain a year, spread over 99 days — about 8.7 mm on a day it rains. [10]
Rainfall measured at MENS, 4.2 km away at 780 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. [10]

…and in much the same climate
The same match on size and services, narrowed to communes whose summers, winters and summer humidity are all close to Saint-Jean-d'Hérans's. All three are required, so this section is absent for the 11.8 % of communes with no humidity station near enough to measure: two temperature axes alone cannot tell a muggy coast from a dry one.
