Vitality score
Vitality score 37.4/100 — Few services (model fr-v0.2).
Confidence: low (sources disagree on Grocery (épicerie / supérette); sources disagree on Restaurant).
Better served than 10 % of the 5,800 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.

…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 Boissy-sous-Saint-Yon'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.
