Quick answer

What does Most densely populated cities show?

Levallois-Perret, France has the highest population density of the 30 cities compared: 28,254 people/km² (Séries historiques en 2023 — Recensement de la population, base des principaux indicateurs, communes de France hors Mayotte, 2023-12-31).

How this list is built

Every row is a published population density observation, ranked highest first. The values were observed between 2020 and 2026. A place appears only when it publishes this exact metric, so an absent place means missing data rather than a low value. Only published cities with at least 20,000 residents and city-level observations qualify.

  • Compare the displayed value, unit, source date and geographic grain together.
  • A city label does not change a regional observation into a city measurement.
