Nantes vs Marne La Vallée
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Nantes leads on any axis where its bar is higher, Marne La Vallée where its is. The cost bar uses a higher-is-cheaper scale, so Marne La Vallée's taller cost bar reflects its lower cost of living, not a higher price.

Data & methodology
Cost scores are normalised from World Bank price-level data. Climate figures (summer highs, winter lows) are drawn from 1991–2020 climate normals. Disaster-safety blends USGS earthquake history (magnitude 4.5+ within 300 km since 1980), tropical-cyclone basin position, flood/elevation exposure and Köppen climate zone. The livability score is the weighted composite of cost, climate and safety. All figures are planning indicators for 2026, not guarantees — verify specifics before relocating.
