Methodology and weights
Safety 70%; healthcare 10%; sport/culture 10%; transport 10%.
Each input is converted to a 0-to-100 percentile inside the eligible cohort. When lower is preferable, notably recorded crime and housing price, the percentile is inverted. The published weights then produce the final score.
Eligible universe
175 Île-de-France communes outside Paris with at least 20,000 residents and complete inputs.
Data vintages: SSMSI 2025; INSEE BPE 2025; INSEE Census housing and activity 2022; Filosofi 2023; DGFiP DVF transactions 2025; official geographic/population reference accessed in 2026.
How to use this ranking
Use it as a disciplined shortlist, not as an instruction to move. Reweight the indicators for your household, verify neighbourhood conditions, transport frequency, schools, rents and current listings, then visit at different times.
Limitations
A score of 100 means the strongest relative position, not perfection. Police-recorded crime reflects reporting and recording practices and may be affected by tourism and commuting. Equipment counts measure presence, not quality, hours or journey time. DVF observes completed sales, not rents or current availability. Vacancy is not the same as an immediately available home. Commune averages hide neighbourhood differences.

Audit and corrections
The calculation joins sources by official commune code and consolidates arrondissement-level equipment data for Paris, Lyon and Marseille. oui stars Travel invites INSEE, SSMSI, DGFiP, municipalities and transport authorities to send corrections or finer comparable data. Documented corrections will be logged and scores recalculated.
