With the housing crisis in full swing, it's hard to imagine that in reality, Paris loses several thousand inhabitants every year. According to INSEE, in 2025, 18,000 people have left the City of Light — a trend that has been confirmed and growing every year since 2012. But here's the thing: this population decline is about to have unprecedented consequences: a new study published by INSEE on August 25, 2026, reveals that due to this population drop, the number of working-age people could also decline sharply by 2050.

Nearly 10% fewer workers in the capital
Between 2022 and 2050, Paris could lose 8.1% of its workforce. A trend that doesn't apply on a regional scale: in fact, the rest of the Île-de-France region should experience some stagnation or even slight growth by 2039. Val d'Oise and Seine-Saint-Denis would be the two departments benefiting from the most dynamic population movement in terms of active workers — respectively +3.4% and +2.3% — notably due to a high birth rate.

Growth followed by a sharp decline
While in 2022, Île-de-France had 6.36 million people in the labor market (employed or job-seeking), according to INSEE forecasts, the region could see a drop to 6.34 million workers by 2050. This significant decline would come after a peak reached around 2039, with 6.50 million active workers in the Île-de-France region.
It was between 2008 and 2022 that the region experienced the strongest growth in the number of workers, with 370,000 new people entering the labor market.
