Mean age, 1052 cities shown. The coloured surface is a local average over 34,852 communes, 98.8% of the country's population, weighted by the population of each one. Every commune with a published value counts, not only the towns in the table. 50 ranked overseas cities are not plotted: they fall outside this map's frame. Projection: longitude compressed by cos(46.3°N), so east-west and north-south distances stay comparable. Source: INSEE, recensement de la population · 2023.

Scope, method and sources

Scope: France, metropolitan and overseas, Corsica and the DROM included. This dataset holds every commune of 10,000 inhabitants or more, plus smaller communes famous enough to be household names, 1,131 in all. It is not the full list of 35,000 French communes, so a village can sit outside a ranking whose extreme it would otherwise hold.

Method and sources: populations are the INSEE legal populations, boundaries and coordinates come from the IGN commune registry, both served by geo.api.gouv.fr. Density is the population divided by the commune's area; distances are measured as the crow flies from the commune's centre. Data read on August 28, 2026.
