Chevry-Cossigny does the important things well, at a cost. Jobs & income is its strong suit (A): 0.5 jobs per working resident; 7.0% unemployment. Walkability is a strength too: 96% of residents live within 800 m of a bakery, and 15% of working residents walk, cycle or take public transport to work. Buying in is costly: at the median price, a 70 m² home costs 8.4 times the median annual income per consumption unit in the intercommunality. Overall, that makes a B+, better than 70% of compared French towns. That places it #4 of 104 in Seine-et-Marne.
