Vitality score

Vitality score 26.5/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 14 % of the 12,766 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

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 18 days a year at or above 30 °C and 55 days at or below 0 °C, over 19 complete years in 1995–2024. [11]

Measured at the CHAPET weather station, 5.4 km away at 42 m; the village itself is at 24 m. [11]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. [11]

Humidity measured at CHAPET, 5.4 km away at 42 m, over 21 summers. [11]

An average of 605 mm of rain a year, spread over 111 days — about 5.5 mm on a day it rains. [11]

Rainfall measured at CHAPET, 5.4 km away at 42 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. [11]

What property sold for

91 houses sold between 2021 and 2025, at a median of 560,000 € — 3,853 € per m² of built surface. [12]

7 flats sold over the same window, at a median of 170,000 € — 3,667 € per m². [12]

The median across Yvelines is 3,657 € per m², so this commune sits about level with it. [12]

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.

…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 Médan'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.
