France has long been considered a special exception in the population patterns of Europe. While countries such as Germany, Italy, and Spain have been dealing with low birth rates and population aging for many years, France has achieved steady population growth thanks to a relatively high birth rate and continuous immigration inflows. However, this special status may undergo a fundamental change in the coming decades. According to the latest forecast by the French National Institute of Statistics and Economic Studies (Insee), although the population will still increase slightly in the short term, from 2037 onwards, the French population will for the first time experience a continuous decline during peacetime. This change marks a profound social transformation that will have far-reaching effects on the economy, social welfare system, and politics.
The End of Historic Growth
According to Insee’s central scenario forecast, by 2070, the French population will be about 65.9 million, a decrease of approximately 3.2 million compared to 2026. Before 2037, the population will still rise slightly, but will then gradually decline.
The key reason lies in the natural growth rate — the difference between the number of births and deaths — which has been negative since 2025. Currently, the number of deaths has already exceeded the number of births. The increase in deaths mainly results from the aging of the post-war baby boom generation, while the number of births continues to decline.
So far, net immigration inflows have compensated for this population decline trend. But according to current calculations, even immigration numbers after 2037 will hardly be able to offset the natural population negative growth, and the population will begin to decrease.
For France, this is a historic turning point. Since the end of World War II, France has been accustomed to continuous population growth. Even during economic difficulties, population trends have remained relatively stable.

Accelerated Social Aging
Beyond the overall population decline, an even more important factor is the change in age structure. The population of France is becoming noticeably older.
Projections show that by 2070, the population under 45 will decrease by about 8.9 million, while the population over 65 will increase by about 5.8 million.
This will significantly change the ratio between the workforce and retirees. Fewer working-age people will have to bear the responsibility of funding pensions, healthcare, and care services to support the growing elderly population.
This trend is not unique to France; almost all developed economies are undergoing a similar aging process. What is special about France is that it has long been considered one of the few parts of Europe where population decline was somewhat contained.
Reasons for the Decline in Birth Rate
France has had one of the highest birth rates in Europe for many years. Family policy measures, a relatively comprehensive childcare system, and financial support have made France an example for many neighboring countries.
Nevertheless, fertility rates have clearly declined in recent years for various reasons:
First, many people are postponing having children. Longer education periods, job instability, and rising housing costs all influence decisions about childbearing.
Second, social and family values have changed. The number of single-person households is increasing, and the influence of traditional family models is weakening.
Third, many families face economic uncertainty. Inflation, high housing prices, and concerns about the future reduce the desire to start large families.
These trends are reflected in almost all Western societies and are difficult to effectively reverse through family policies.
Immigration as a Population Stabilizer
Recent projections highlight the important role of immigration in France’s population development. Without immigration, France’s population would begin to decline even earlier.
Immigration plays multiple roles: stabilizing the population size, partially alleviating the aging age structure, and meeting labor demand. Especially in industries such as caregiving, construction, catering, and healthcare, immigrant labor has played a key role.
At the same time, immigration issues are highly controversial in French politics. Although businesses and some economic sectors depend on additional labor, immigration topics often trigger intense political debates.
Population projections indicate that without immigration inflows, France will find it difficult to achieve long-term population stability.
Impact on the Economy and Social Welfare
Population decline and aging pose significant challenges for the French economy.
The reduction of the working-age population leads to a lower labor supply. Companies may find it difficult to fill job vacancies. Currently, several industries are already facing a shortage of skilled workers.
At the same time, increased spending on pensions, healthcare, and caregiving puts financial pressure on the social welfare system. The intense debates on pension reform in recent years indicate that political conflicts may intensify in the future.
Regional disparities will also deepen. Large cities such as Paris, Lyon, and Toulouse may continue to attract population, while rural areas face further population loss. Infrastructure, schools, and public services must adapt to the reality of population decline.
Forecast Uncertainties
Insee clearly points out that these are not exact predictions, but scenario simulations based on current trends. The actual situation may differ considerably.
Depending on varying assumptions about birth rates, life expectancy, and immigration, the population forecast for France in 2070 ranges between 61 million and 71 million. The differences reflect the reality that population development is strongly influenced by political, economic, and social changes.
The only thing almost certain is the trend of population aging. Whether France will experience a long-term population decline or remain stable is still uncertain.
But there is no doubt that France is facing a profound demographic transformation. The coming decades will test how France responds to the economic and social challenges posed by an aging society. The real challenge is not the change in total population, but how to manage the increasingly imbalanced age structure. The answer to this question will determine France’s competitiveness, solidarity, and capacity for action in the second half of the 21st century.
