A good place to live, if you can afford it. It does especially well on health — after allowing for care homes, deaths from 2016 to 2025 were 30% below expected, against 12% below for the median of compared French towns. Marly-le-Roi’s overall grade, A−, puts it better than 79% of compared French towns. In the ranking it comes #19 of 91 in Yvelines. Fewer journeys need a car: 99% of residents live within 800 m of a bakery, and 45% of working residents walk, cycle or take public transport to work. The drawback is cost of living — at the median price, a 70 m² home costs 7.8 times the median annual income per consumption unit in the intercommunality. Its other grades sit near the middle: B− for safety and B for schools.
