0.7%. This is the barely noticeable yet very real proportion of French people who have crossed the threshold of 90 years. This figure, derived from Insee data, tells the story of an aging France, where nearly 800,000 people today are nonagenarians. This represents about 1.2% of the total population, and within this group, women are nearly four times more numerous than men.
For several decades, this progression has not weakened. The baby boomer generation is aging, and with it, the population of nonagenarians is rising. More numerous than twenty years ago, these French people aged 90 and over embody a demographic transition whose acceleration is no longer in doubt.

Aging in France: how longevity shapes our society
The structure of French society is transforming under the effects of aging. Life expectancy continues to increase: 85.7 years for women, 80 years for men, according to the latest data. These advances are the result of medical progress, enhanced prevention, and improved living conditions since the second half of the 20th century. Gradually, baby boomers are occupying an increasingly visible place in society.
This rise in nonagenarians challenges the support for aging. Nearly 800,000 people are now 90 years old or older. The percentage of the population aged 90 in France stands at around 1.2%. This figure influences the shape of the age pyramid and increases pressure on autonomy support, demand for adapted housing, home services, and specialized facilities. Needs are multiplying.

Statistics paint a contrasting picture: the vast majority of nonagenarians are women, a consequence of early male mortality. This reality leads to situations of isolation, precariousness, and loss of autonomy. In the face of these challenges, French society is compelled to rethink its public policies and solidarities.
Several challenges are emerging that require immediate attention:
- prevention of loss of autonomy,
- adaptation of housing,
- combatting isolation,
- financing pensions and healthcare.
French society is distinguished by the diversity of paths, the originality of its responses, and the particular distribution of ages. It is these singularities that shape the contours of today’s France.
What percentage of the French population is 90 years old or older today?
The data from the Insee census highlights a profound, long-silent mutation. In 2023, France now has nearly 800,000 people aged 90 and over, accounting for about 1.2% of the metropolitan population. This is a level never reached before.
Women overwhelmingly dominate this category. Nearly 80% of nonagenarians are female, reflecting the higher male mortality in adulthood. The age pyramid thus widens significantly at its peak, particularly on the female side. Among centenarians, the trend is even more pronounced: over 30,000 today, with the vast majority being women.
The aging population disrupts perspectives. By 2040, Insee predicts that the share of nonagenarians could double due to the aging of baby boomers. This evolution raises questions: how to adapt health, housing, and public policies? These questions are gradually becoming pressing, as longevity asserts itself as one of the major markers of the century in France.

Crossed perspectives: France facing global demographic aging
France, with its 68 million inhabitants, is moving through a decade where the issue of aging is no longer confined to its borders. National life expectancy rivals the highest European standards: nearly 85 years for women, around 79 for men. However, the transformation of the age pyramid is evident everywhere: the base is shrinking, the top is growing, signaling the rise of older generations.
A quick overview of Europe shows neighbors like Italy or Germany slightly ahead in the share of nonagenarians, but the French progression remains steady. This dynamic is explained by an increase in lifespan, declining mortality after age 65, and the advance of baby boomers into old age. Demographic projections are thus being disrupted, and the phenomenon is here to stay.
This aging is not unique to France. Japan, Germany, Spain… Everywhere, society is reorganizing to prevent loss of autonomy, adapt housing, combat isolation, and anticipate healthcare needs. In the face of these challenges, France observes, adjusts, experiments, and tries to preserve social ties. It thus joins the major nations confronted with the surge of extreme ages, invited to reinvent its solidarities and shape a new vision of old age.
