Method and limits

What these tables say — and what they don’t.

Scores are composite: each criterion carries a published weight, shown under each national ranking.
Towns are ranked within a population tier (5,000–20,000, 20,000–100,000, over 100,000 inhabitants). Towns under 5,000 inhabitants are not ranked.
A town missing the data for a criterion is left out of that ranking, never ranked last by default.
This is not a league table of lived quality of life: these figures reflect the public data available, with its blind spots and publication delays.
Crime figures are offences recorded by the police and the gendarmerie: they depend on whether victims report them and on how present the services are.
