NUTS-3 FR106 · France
Seine-Saint-Denis
Seine-Saint-Denis generates €82bn of GDP across 1.7m residents. Its Opportunity Index of 74.7/100 puts it in the upper quartile of EU regions, led by market access and economic scale. Its economy has grown +4.3%/yr over five years and accelerating, with the employment rate up 2.3pp. On quality of life it ranks strongest for health (98th EU percentile) and weakest for clean environment (16.7th).
Long-run trajectory · EU percentile of real GDP per head, 1995–2024
Long-run riser66 → 81 EU percentile since 1995 (+15 ranks)
Yearly EU-wide percentile of real GDP per head (ARDECO regional accounts, constant 2020 prices, derived over population). 50 = the EU median that year; percentiles are scale-free, so decades are directly comparable. See the backtest for what long-run prosperity ranks do — and don't — anticipate.
