Grez-sur-Loing’s standout strength is health (B+) — after allowing for care homes, deaths from 2016 to 2025 were 21% below expected, against 12% below for the median of compared French towns. It also does well on walkability: 1% of residents live within 800 m of a bakery, and 17% of working residents walk, cycle or take public transport to work. Buying in is costly: at the median price, a 70 m² home costs 8 times the median annual income per consumption unit in the intercommunality. Schools are weaker too — brevet results 4 points below the expected rate.
