Vitality score

Vitality score 46.7/100 — Partly served (model fr-v0.2).

Confidence: high.

Better served than 65 % of the 10,590 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.

Access and surroundings

Which way the everyday services lie

In the commune Bakery, Food shop, Primary school, GP Pharmacy — 2.2 km S Straight-line, from the mairie, in the direction given. Services in the same town share a spoke. Distance is not travel time: a pass or an estuary can double it.

Bakery (Chavenay): 0.4 km to the west (straight line). ^[8]

Food shop (Chavenay): 0.2 km to the west (straight line). ^[8]

GP (Chavenay): 0.2 km to the south (straight line). ^[8]

Primary school (Chavenay): 0.2 km to the west (straight line). ^[8]

Climate

Where this sits nationally

Days at or above 30 °C 11.2

Days at or below 0 °C 32.2

Muggy days a summer 1.2

Each track runs from the 5th to the 95th percentile of the 34,141 communes with that measurement; the tick is the median. A value beyond either end sits at the end and is marked ▸.

An average of 11 days a year at or above 30 °C and 32 days at or below 0 °C, over 30 complete years in 1995–2024. ^[10]

Measured at the TRAPPES weather station, 9 km away at 167 m; the village itself is at 86 m. ^[10]

The village sits 81 m below the station, so each day's reading was shifted by 5.71 °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 TRAPPES, 9 km away at 167 m, over 30 summers. ^[10]

That station sits 81 m above the village, so each day's humidity was shifted by 4.22 °C per km before the muggy days were counted. ^[10]

An average of 641 mm of rain a year, spread over 116 days — about 5.5 mm on a day it rains. ^[10]

Rainfall measured at CLAYES, 3.3 km away at 115 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 Chavenay'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.
