Secondly, the societal image of the family is changing. The number of single-person households is growing, while traditional family models are losing significance.
Thirdly, the economic insecurity of many households restrains family expansion behavior. Inflation, high real estate prices, and concerns about the future reduce the willingness to start larger families.
These trends can be observed in almost all Western societies and can only be limitedly influenced by family policies.
Migration as a Demographic Stabilizer
Current projections clearly show the importance immigration now holds for population development. Without migration, France would have been losing inhabitants much earlier.
Migration serves several functions. It stabilizes the population size, partially rejuvenates the age structure, and helps meet the demand for labor. Immigrants already play a central role especially in sectors such as elderly care, construction, hospitality, or healthcare.
At the same time, migration remains one of the most politically controversial issues in France. While companies and parts of the economy depend on additional workforces, immigration is regularly the subject of heated political debates.
Demographic forecasts, however, emphasize that a lasting stabilization of the population without immigration hardly seems possible.
Consequences for the economy and welfare state
A shrinking and aging population presents significant challenges for the French economy.
Fewer people of working age means a smaller labor supply in the long term. Companies may have difficulty filling open vacancies. Even today, many sectors face a shortage of skilled workers.
At the same time, spending on pensions, health, and care is rising. This puts pressure on the financing of the welfare state. The controversial debates about pension reform over recent years provide a preview of the political conflicts that will likely increase in the future.
Regional differences are also likely to intensify. While metropolitan areas such as Paris, Lyon, or Toulouse may still be able to attract residents, rural areas risk additional population loss. Infrastructure, schools, and public services will need to be adapted there to the declining number of inhabitants.
Forecasts are not certainties
Insee explicitly emphasizes that these are not predictions, but projections based on current trends. The actual development may differ significantly.
Depending on assumptions about birth rates, life expectancy, and migration, the scenario for 2070 ranges from about 61 to 71 million inhabitants. The differences show how strongly demographic developments can be influenced by political decisions, economic frameworks, and societal changes.
Only the aging of the population is considered almost certain. Whether France will indeed lose inhabitants over a long period or can stabilize its population number remains open.
However, the fact is that the country faces a profound demographic transformation. The coming decades will reveal whether France finds ways to economically and socially manage the consequences of an aging society. The real challenge lies less in the absolute population number and more in the question of how a modern community deals with an increasingly unbalanced age structure. The answer to this question will largely determine how competitive, solidaristic, and capable of acting France will be in the second half of the 21st century.

France was long seen as a demographic exception in Europe. While countries like Germany, Italy, or Spain have struggled for years with low birth rates and an aging society, France was able to steadily increase its population thanks to relatively high birth rates and continuous immigration. But this special position could fundamentally change in the coming decades. According to recent forecasts from the French statistical office Insee, the population will initially still increase slightly, but from 2037 onwards it will decline permanently for the first time in peacetime. This development marks a profound societal change with far-reaching consequences for the economy, welfare state, and politics.
The end of a historic growth
According to the so-called central scenario of Insee, France will have approximately 65.9 million inhabitants in 2070. That is about 3.2 million fewer than in 2026. The population will still increase slightly until 2037, after which it will steadily decline.
The decisive reason lies in the so-called natural balance, the difference between births and deaths. This has been negative since 2025. More people now die than are born. While the number of deaths initially increases due to the aging of the post-war baby boom generation, at the same time the number of births is declining.
So far, net immigration has been able to compensate for this decline. But according to current calculations, even migration will no longer be sufficient to offset the natural deficit from 2037 onwards. The population will then begin to shrink.
For France, this would be a historic turning point. Since the end of the Second World War, the country had been accustomed to steady population growth. Even in economically difficult times, demographic development remained relatively stable.
The acceleration of aging
More important than the overall decline is the change in the age structure of the population. France is becoming significantly older.
According to projections, the number of people under 45 years old will decrease by about 8.9 million by 2070. At the same time, the group aged 65 and over will grow by about 5.8 million people.
As a result, the ratio between the working population and retirees changes significantly. Fewer and fewer people of working age will have to finance pensions, healthcare, and elderly care for a growing number of elderly people.
This development is not exclusively a French phenomenon. Almost all developed economies are experiencing similar aging. However, France stands out because it was long seen as one of the few European countries that partially escaped demographic decline.
Why the birth rate is declining
France had for decades one of the highest birth rates in Europe. Family policy measures, a relatively well-developed childcare system, and financial support made the country an example for many neighbors.
Nevertheless, the fertility rate has significantly declined in recent years. Several factors contribute to this:
Firstly, many people delay starting a family until a later age. Longer education periods, uncertain job conditions, and rising housing costs influence the decision to have children.
Secondly, the societal image of the family is changing. The number of single-person households is growing, while traditional family models are losing significance.
Thirdly, the economic insecurity of many households restrains family expansion behavior. Inflation, high real estate prices, and concerns about the future reduce the willingness to start larger families.
These trends can be observed in almost all Western societies and can only be limitedly influenced by family policies.
