In France, more than one in four people is now over 60 years old. This ratio, which was still minority thirty years ago, reshapes the balance between generations, the financing of pensions, and the organization of care. Understanding the key figures of French demographic aging means grasping what is changing concretely in the collective life of the country.
Dependency Ratio: The Figure that Summarizes the Pressure
Before discussing average age or life expectancy, one indicator deserves to be understood: the dependency ratio. It compares the number of elderly people (65 years and older) to the number of working-age individuals (15-64 years).

Why does this ratio matter so much? Because it directly reflects the economic burden borne by the working population. The higher it rises, the more each worker finances, through their contributions, a growing share of pensions and healthcare expenses.
In France, this ratio has been continuously increasing for two decades. INSEE projections anticipate a sharp rise in the dependency ratio until 2050, although this increase remains less pronounced than in other European countries such as Italy or Germany. Data on the percentage of the aging population in France helps to measure the extent of this long-term transformation.

The pension reform of 2023 (law of April 14, 2023) has begun to change this picture. Starting in 2024, the proportion of 60-64 year-olds still in employment has increased. As a result: economic dependency is progressing less rapidly than the share of those aged 65 and over. The raising of the retirement age partially alleviates the pressure, without eliminating it.
Share of Those Aged 60 and Over, and 75 and Over: What Recent Data Says
As of January 1, 2024, France had 68.4 million inhabitants. The population aged 60 and over represented 27.7% of the total, compared to 19.6% in 1994. In three decades, the share of seniors has gained more than eight points.
You may have noticed that discussions often focus on “those over 65”? This threshold masks a more nuanced reality. Those over 75 make up 10.4% of the population at the beginning of 2024, an increase of 1.6 points since 2010. This age group has the most significant impact on the healthcare system and the management of loss of autonomy.
According to INSEE estimates, the share of those over 75 is expected to reach 16.4% by 2050, effectively doubling compared to the early 2010s. The share of those aged 65 and over has already increased by 5.3 points since 2004, reaching 21.8% by the end of 2024.
Conversely, the proportion of those under 20 has decreased by 2.1 points over the same period. The gap between seniors and youth is continuously widening: those over 60 now exceed those under 20 by 4.4 points.
Regional Disparities in Aging in France
The national average conceals considerable disparities between regions. The rural departments of the Massif Central, the “diagonal of emptiness,” and certain areas of the Grand Est show the highest shares of those aged 75 and over.
Since 2023-2024, a counterintuitive phenomenon has emerged in these same areas: the share of those aged 75 and over tends to stabilize, or even slightly decrease. The excess mortality related to Covid-19 and the general demographic attrition in these territories explain this trend, while the national proportion continues to rise.
Updated regional projections from INSEE indicate a significantly faster aging process in the Atlantic West and the Southwest. The Pays de la Loire, Brittany, and Nouvelle-Aquitaine are welcoming a steady influx of retirees from Île-de-France or major metropolitan areas. This residential migration phenomenon accelerates local aging well beyond the natural dynamics.
At the intra-urban level, the revised aging index in 2024 reveals marked contrasts within major urban areas. Some neighborhoods concentrate an elderly population while others remain very young, complicating the planning of local services.
- The Atlantic West and Southwest are aging faster than the average, driven by retiree migrations
- The rural departments in central France have recently stabilized due to excess mortality and demographic attrition
- Île-de-France remains the least affected region by aging, thanks to its young active population and incoming migration flows
- Intra-urban disparities complicate local planning for elderly care and services
Life Expectancy at 65 and Demographic Projections for 2050
Life expectancy at 65 is steadily increasing in France. This is known as “aging from the top”: generations are living longer after 65, which mechanically increases the duration of pension payments and the period of reliance on care.
This aging from the top combines with the aging of the baby boom generations, born between 1946 and 1964. These large cohorts are gradually crossing the threshold of 75 years, fueling the rapid rise of this age group.
Projections for 2050 depict a France where those over 75 will weigh as much as those aged 60-74, each representing about 16%. The age structure of the country is thus deforming towards the top of the pyramid, with direct consequences on three major budgetary items:
- Pension expenditures, under systemic pressure despite the 2023 reform
- Care for loss of autonomy, whose cost remains the most uncertain according to analyses by the Court of Auditors
- The labor market, where the renewal of the workforce is becoming slower in certain sectors
The sustained decline in French birth rates, which has been underway for several years, amplifies this dynamic. Fewer births and longer lives produce a double-engine aging that public policies struggle to absorb.
The aging of the French population is not a distant trend. The figures for 2024 show a transformation already well underway, with territorial disparities making any uniform response inadequate. The budgetary decisions of the coming years will largely hinge on the ability to finance pensions and autonomy without overwhelming the remaining active population.
