Each edition grades its towns against each other only.
Home to 4,965 people, this town lies in Yvelines, Île-de-France.
A good place to live, if you can afford it. At A− overall, Saint-Nom-la-Bretèche ranks #23 of 91 in Yvelines. It comes out better than just over three quarters of compared French towns. Health is its strong suit: after allowing for care homes, deaths from 2016 to 2025 were 40% below expected, against 12% below for the median of compared French towns. What holds it back is cost of living — at the median price, a 70 m² home costs 8.6 times the median annual income per consumption unit in the intercommunality. Schools are weaker too: bac results 3 points below the expected rate; brevet results 6.2 points below the expected rate.
