Overview
- INSEE reports 651,000 deaths versus 645,000 births in 2025, producing a natural balance of −6,000.
- Fertility fell to 1.56 children per woman, the lowest since World War I, with births down 2.1% from 2024 and about 24% from 2010.
- Deaths rose 1.5% as ageing increased mortality and a particularly severe January influenza wave added to the toll, even as life expectancy hit record highs.
- Despite the natural decline, net migration of about +176,000 lifted the population to 69.1 million on Jan. 1, 2026, with people 65+ now 22.2% of the population versus 22.5% under 20.
- The crossover places France within an EU-wide pattern of negative natural growth since 2015, and comes far earlier than INSEE’s central projection for the mid‑2030s.
