Some subjects shine; others lag. Its strongest is walkability — 95% of residents live within 800 m of a bakery, and 27% of working residents walk, cycle or take public transport to work. Housing is expensive: at the median price, a 70 m² home costs 6.8 times the median annual income per consumption unit in the intercommunality.
