The data are hard on it. Its lowest grade is for cost of living: at the median price, a 70 m² home costs 9.6 times the median annual income per consumption unit in the intercommunality. It is easy to get around without a car: 100% of residents live within 800 m of a bakery, and 45% of working residents walk, cycle or take public transport to work. Health is a strength: after allowing for care homes, deaths from 2016 to 2025 were 21% below expected, against 12% below for the median of compared French towns. Overall, that makes a C−, good for #30 of 44 in Val-de-Marne. That leaves it better than nearly a fifth of compared French towns.
