France’s population is still growing overall, but the demographic forces behind that growth are changing. Some regions are attracting new residents and expanding their metropolitan areas, while others are losing population or becoming increasingly dependent on migration to offset falling births and rising deaths.
The latest figures from the French National Institute of Statistics and Economic Studies, known as INSEE, reveal a particularly important turning point. France had an estimated 69.1 million residents on January 1, 2026. In 2025, however, deaths exceeded births for the first time since the end of the Second World War. The national population increase therefore no longer tells the whole story about the country’s demographic health.
Regional differences are central to understanding this shift. Île de France, the region surrounding Paris, remains the country’s largest population centre, but Paris itself is losing residents. Occitanie, Nouvelle Aquitaine, Brittany and Pays de la Loire have benefited from population growth, including migration from other parts of France. Meanwhile, parts of northeastern and central France face slower growth, population ageing and a weaker natural balance.
The key question is no longer simply how many people live in France. It is where they live, why they move, how many children are being born, and whether local economies and public services can adapt to increasingly different demographic realities.
How is France’s population distributed geographically?
France’s population is concentrated around major metropolitan areas, employment centres and transport networks. However, its administrative regions contain very different settlement patterns, ranging from the densely populated Paris region to sparsely populated rural departments, mountain communities and overseas territories.
INSEE estimates place metropolitan France at approximately 66.8 million residents at the beginning of 2026, compared with about 2.29 million across the five overseas departments. Together, these figures produce a national population estimate of approximately 69.1 million. These are provisional population estimates, not a count conducted on a single day.
Population by administrative region
The table below uses INSEE’s population estimates for January 1, 2026, alongside the published 2023 figures. The 2026 estimates are provisional. Changes between the two dates indicate the overall direction of population movement, rather than a complete explanation of its causes.
| Administrative region | Population in 2026 | Change since 2023, approximately |
|---|---|---|
| Île de France | 12,594,502 | +131,400 |
| Auvergne Rhône Alpes | 8,303,191 | +97,600 |
| Occitanie | 6,246,988 | +122,300 |
| Nouvelle Aquitaine | 6,241,784 | +91,300 |
| Hauts de France | 5,965,764 | −26,400 |
| Grand Est | 5,544,271 | −19,100 |

Three patterns stand out.
First, Île de France remains by far the largest region. Its population is more than twice that of Auvergne Rhône Alpes, the second largest region.
Second, southern and western regions have recorded substantial gains. Occitanie, Provence Alpes Côte d’Azur, Nouvelle Aquitaine and Pays de la Loire have all added residents since 2023.
Third, several regions have experienced stagnation or contraction. Hauts de France, Grand Est and Bourgogne Franche Comté recorded lower populations in the 2026 estimates than in 2023. These changes matter because declining regional totals can affect school planning, labour supply, healthcare provision and the long term viability of local services.
The figures also demonstrate why a regional ranking should not be interpreted as a simple measure of economic success. A region can grow because it attracts retirees, working age adults, international migrants or families. Each group creates different demands on housing, schools, healthcare and employment.
Metropolitan France versus overseas departments
Geographic coverage is essential when comparing French population figures.
Metropolitan France consists of mainland France and Corsica. The five overseas departments included in the standard national population total are Guadeloupe, Martinique, French Guiana, Réunion and Mayotte.
The overseas departments have markedly different demographic profiles. French Guiana and Mayotte have much younger populations than metropolitan France, while Guadeloupe and Martinique face population ageing and declining population totals. Réunion occupies an intermediate position, with a younger population than metropolitan France but a demographic profile that is also changing.
These differences make a single national average insufficient for understanding local needs.
Mayotte, for example, had an estimated population of 338,208 in January 2026, while French Guiana had 298,554. The two territories have high proportions of children and young people, but their needs differ from those of regions where older residents represent a much larger share of the population.
Overseas France must also be handled consistently in historical comparisons. Estimates for Mayotte rely on a different combination of census information and demographic estimates from those used for many other territories. Comparisons should therefore identify the geographic coverage and reference year rather than combining figures from incompatible series.
The most densely populated and least densely populated areas
Population density explains why two regions with similar population totals can face very different infrastructure challenges.
INSEE’s 2023 census based figures put the density of Île de France at approximately 1,038 residents per square kilometre. The corresponding national figure was about 108 residents per square kilometre. The Paris region therefore has almost ten times the national population density.
By contrast, regions such as Corsica contain extensive mountainous and sparsely populated areas. Even within larger regions, residents are often concentrated in a few metropolitan centres while smaller towns and rural communities experience weaker demand.
| Area | Population pattern | Main demographic pressure |
|---|---|---|
| Île de France | Very high density around Paris and its suburbs | Housing affordability, transport capacity and movement away from central Paris |
| Auvergne Rhône Alpes | Concentration around Lyon, Grenoble and other urban centres | Balancing metropolitan growth with ageing rural communities |
| Occitanie | Strong urban growth around Toulouse and Montpellier | Housing, infrastructure and pressure on expanding suburbs |
| Nouvelle Aquitaine | Growth around Bordeaux and selected coastal and inland areas | Uneven growth between cities, coastal areas and rural departments |
| Central and northeastern rural areas | Lower density and weaker growth in many localities | Ageing, recruitment difficulties and access to services |
This geographic divide affects public spending. Dense areas may require more housing, public transport and school capacity. Sparse areas may need to maintain roads, medical facilities and public transport over long distances despite having fewer residents to support the costs.
Which parts of France are experiencing population growth or decline?
Regions with the strongest population growth
The recent population figures show gains in several southern and western regions, as well as in Auvergne Rhône Alpes.
Occitanie illustrates the importance of combining regional totals with local analysis. Its population reached approximately 6.25 million in 2026, up from 6.12 million in 2023. The region includes expanding metropolitan areas such as Toulouse and Montpellier, alongside rural departments with much older populations.
Nouvelle Aquitaine also gained residents, reaching approximately 6.24 million. Growth has been associated with the attraction of Bordeaux and other urban centres, coastal settlement and movement into smaller towns. However, the regional average does not mean that every department is expanding at the same pace.
Pays de la Loire has a smaller population than the largest regions but has continued to grow. Its metropolitan employment centres, including Nantes and Angers, attract households and businesses. Brittany has also gained residents, although the region is ageing and the number of births has fallen.
These patterns reflect both natural change and migration. A region may record more deaths than births yet still grow because more people move in than move out. Conversely, a region with a relatively young population can experience slow growth if enough residents leave.
Regions with declining or stagnant populations
Hauts de France, Grand Est and Bourgogne Franche Comté have experienced weaker recent population trends than many southern and western regions. Centre Val de Loire and Normandy have been closer to stagnation in the latest comparison, although individual departments differ substantially.
The long term picture is more revealing than a single three year comparison. INSEE’s regional projections published in 2022 and updated through its detailed results in 2024 indicate that one third of metropolitan regions could lose population by 2070 under the central scenario. The projections identified particularly difficult long term trajectories in parts of northeastern and central France, while southern and western regions were expected to benefit from migration.
The distinction between a current estimate and a long term projection is important. A region losing residents today might stabilise if migration increases, while a currently growing region could slow as its population ages and births decline.
Population decline also tends to be uneven within regions. A regional capital may continue to attract students and professionals while surrounding rural departments lose younger adults. The result is a concentration of opportunity in selected urban areas rather than uniform regional growth.
Why absolute growth and percentage growth tell different stories
Absolute population change measures the number of people added or lost. Percentage change measures the scale of that change relative to the population at the beginning of the period.
Île de France added approximately 131,400 residents between the 2023 and 2026 estimates. Corsica added around 10,200. The latter’s smaller absolute increase represents a more noticeable change relative to its much smaller population.
This distinction matters when evaluating public services. A large region may need thousands of additional homes even if its percentage growth is modest. A small region can experience rapid percentage growth without adding enough residents to sustain every local service or business.
The reverse is true for declining regions. Losing several thousand residents can have a severe effect on a small town, particularly when younger residents leave and the remaining population is older.

Why are some regions growing while others lose residents?
Births, deaths and regional age structures
France’s national demographic balance changed significantly in 2025. INSEE recorded 643,905 births and 645,662 deaths in its detailed vital statistics series, producing a negative natural balance of approximately 1,800. The preliminary annual demographic assessment reported a negative balance of around 6,000, reflecting differences between provisional and final figures. Births were approximately 24% below their 2010 level.
The total fertility rate fell to approximately 1.56 children per woman in 2025, its lowest level since the end of the First World War. The decline continued into the first five months of 2026, according to INSEE’s published birth statistics.
Falling births affect regions differently because their populations have different age structures. Regions with more women in childbearing ages may continue to record more births even when fertility falls. Older regions may experience more deaths simply because a larger share of residents are in older age groups.
The Île de France region demonstrates this contrast. It retains a substantial natural population surplus, even as Paris itself loses residents. INSEE reported 148,772 births and 79,431 deaths in the region during 2025, while the regional population increased by approximately 45,200 over the year.
A negative natural balance does not automatically mean a region is failing. It may reflect longer life expectancy and a mature age structure. However, sustained low fertility combined with the retirement of large generations creates pressure on labour markets, schools and healthcare.
Internal migration between French regions
Movement within France is a major factor in regional population change.
Students move to cities with universities. Graduates often remain where employment opportunities are concentrated. Families may move to suburbs or smaller cities in search of more space, while retirees may choose coastal areas or towns with attractive climates and established services.
The effects differ according to age and income. A region gaining young professionals can increase its future workforce and demand for housing. A region gaining retirees may see stronger demand for healthcare and age friendly housing, but not necessarily the same increase in school enrolment.
Remote and hybrid working have also widened the range of possible residential choices for some occupations. However, access to reliable transport, broadband, schools and healthcare continues to shape where households can realistically settle.
Migration is not a single process. A person moving from Paris to Nantes increases the population of one region while reducing that of another. International migration can add residents to France overall, but its regional impact depends on where newcomers settle, work and study.
International migration and major urban centres
International migration is particularly relevant to metropolitan areas, where universities, employers, transport links and established communities attract new residents.
Paris and its suburbs contain a large share of France’s international population. Other urban centres, including Lyon, Toulouse, Marseille, Montpellier, Bordeaux and Strasbourg, also attract international students, workers and families.
Migration can offset a negative natural balance, but its effect should not be overstated. The national population balance depends on births, deaths and net migration, while regional population estimates also reflect movement between French territories. INSEE’s apparent migration balance combines movements that cannot always be separated precisely into internal and international components at the regional level.
Migration also interacts with housing affordability and employment. New arrivals may strengthen the workforce, support local businesses and increase demand for homes. Where housing supply and infrastructure do not keep pace, population growth can also intensify pressure on rents, transport and public services.
Employment, universities and housing affordability
Employment opportunities are a major driver of settlement. Regions with diversified economies and growing service sectors can attract younger adults, while areas dependent on declining industries may struggle to retain them.
Universities contribute to this pattern. Large student populations support rental housing, public transport, retail and cultural services. Some students remain after graduation, turning temporary educational migration into longer term population growth.
Housing affordability creates another layer of complexity. Expensive central districts can push households towards outer suburbs and neighbouring towns. This may increase the population of a metropolitan area even while its historic core loses residents.
The Paris region illustrates this mechanism. Paris had an estimated 2.05 million residents at the start of 2026, and its population declined by approximately 18,000 during 2025. Yet the wider Île de France region grew, with particularly strong gains in Seine Saint Denis and Seine et Marne.
This is not a contradiction. The population of a city proper can fall while the wider metropolitan region expands, because households relocate across administrative boundaries rather than leaving the entire region.
How is regional population change affecting public services?
School closures and changing enrolment
Falling births are beginning to change the long term outlook for schools. Smaller birth cohorts eventually enter nursery and primary education, then move into secondary schools. If enrolment falls for several years, local authorities must decide whether to retain small schools, reorganise catchment areas or consolidate facilities.
The effects are especially significant in rural communities. A school may be more than an educational facility: it can support local employment, attract families and sustain community life. Closing it may save public funds in the short term but increase travel times and make an area less attractive to young households.
Growing regions face the opposite problem. Expanding suburbs may require new classrooms, teachers and school transport even while national enrolment falls.
School planning therefore needs local birth projections rather than national totals alone.
Healthcare access and medical staffing
Population ageing increases demand for chronic disease management, primary care, specialist services and long term support. The challenge is particularly difficult in rural departments where medical practices and hospitals may be far apart.
A region with a large older population can require more healthcare capacity even if its total population is stable or declining. A growing city can face waiting lists because the workforce and facilities have not expanded as quickly as its population.
Medical staffing is also shaped by geography. Professionals tend to concentrate in larger urban centres with hospitals, training facilities and broader employment opportunities. Rural communities may need incentives, shared practices, telemedicine and better transport connections to maintain access.
Public transport and local infrastructure
Population change alters infrastructure demand in two directions.
Growing metropolitan areas need additional public transport capacity, housing, water services, roads and utilities. If infrastructure investment lags, congestion and housing costs can rise.
Declining areas face a different financial problem. Maintaining roads, bus routes, local administrative offices and utility networks becomes more expensive per resident when the population shrinks.
The policy challenge is not simply to encourage population growth everywhere. It is to match infrastructure to realistic local demand while preserving access to essential services in areas with fewer residents.
How do Paris, other cities and rural areas compare?
Population change in the Paris region
Île de France remains the country’s largest regional population centre, with nearly 12.6 million residents in 2026. Its demographic pattern combines a strong natural surplus with movement away from some central areas.
Paris city has lost residents over several years, while several suburban departments have grown. Housing costs, smaller household sizes, the search for more living space and changing household composition all help explain why the centre and its surrounding region can move in different directions.
The regional challenge is balancing employment concentration with affordable housing and transport. If workers cannot afford to live near their workplaces, commuting distances increase and housing pressure spreads across the metropolitan area.
Growth around regional cities
Toulouse, Montpellier, Bordeaux, Nantes and Rennes illustrate the broader attraction of regional metropolitan centres. They combine universities, employment opportunities, transport infrastructure and cultural amenities.
Their expansion can benefit surrounding towns through commuting, business investment and new housing. But growth can also create pressures on agricultural land, public transport, water supply and local infrastructure.
The benefits are not distributed equally. Some smaller towns gain residents as households move out of expensive city centres, while others remain disconnected from employment and transport networks.
Rural depopulation and local resilience
Rural France is not uniformly declining. Some coastal communities, commuter towns and attractive smaller cities have gained residents, while other areas face long term population loss.
Ageing is a major concern in parts of central and northeastern France. When younger residents leave for education and employment, the remaining population becomes older. This can weaken the local workforce and reduce demand for schools, shops and other services.
Local resilience depends on more than population totals. Digital connectivity, access to healthcare, transport, affordable housing, tourism, agriculture and small business development all influence whether a community can retain residents.
What do regional population projections show through 2050?
INSEE’s regional projections provide a framework for understanding possible long term change, but they should not be treated as certain predictions.
The widely used 2018 to 2070 projection series suggests that southern and western metropolitan regions are better positioned for continued growth, largely because of migration. Occitanie, Pays de la Loire, Brittany, Nouvelle Aquitaine, Corsica and Auvergne Rhône Alpes feature among the regions with positive projected long term growth in the central scenario. Several northeastern and central regions face weaker trajectories.
The same projections anticipate ageing across the country. Even regions with population growth are expected to have more older residents, creating additional demand for healthcare and retirement support.
The projections are based on assumptions about fertility, mortality and migration. If fertility remains lower than assumed, life expectancy changes, or migration patterns shift, actual population levels can differ substantially from the central scenario.
| Projection consideration | Likely regional implication |
|---|---|
| Lower fertility | Smaller future school cohorts and, later, smaller working age populations |
| Longer life expectancy | More residents reaching older ages and greater demand for care |
| Continued migration towards the south and west | Greater pressure on housing and infrastructure in receiving regions |
| Persistent outmigration from weaker labour markets | Greater risk of population decline in some rural and industrial areas |
| Changes in international migration | Different population outcomes depending on settlement patterns and employment |
The key insight is that France is not heading towards one uniform demographic future. The national total may stabilise or grow slowly while individual regions experience expansion, ageing, stagnation or decline.
Conclusion
France’s population geography is increasingly shaped by the interaction of falling births, longer lives and migration. Île de France remains the largest region, but growth within it is uneven. Southern and western regions have attracted residents, while parts of the northeast and centre face weaker demographic trends.
The negative natural balance recorded in 2025 marks an important turning point. It does not mean that France’s population must immediately decline, but it does mean that migration is becoming more important in determining the country’s overall population trajectory.
For policymakers, businesses and local authorities, the most useful question is not simply which region has the most residents. It is whether each region can retain working age people, provide services for an ageing population and adapt infrastructure to changing local demand.

Frequently asked questions
1. Which region of France has the largest population?
Île de France, which includes Paris and its surrounding departments, is France’s largest region. INSEE estimated its population at approximately 12.59 million on January 1, 2026.
2. Which parts of France are losing population?
Recent estimates show weaker population trends in Hauts de France, Grand Est and Bourgogne Franche Comté. Within otherwise growing regions, individual rural departments and cities may also lose residents.
3. Is Paris still growing?
Paris city has been losing residents, while the wider Île de France region continues to grow. The difference reflects movement between Paris and its suburbs, alongside natural population change.
4. Why are some French rural areas losing residents?
Common factors include limited employment opportunities, the departure of younger adults for education and work, population ageing and reduced access to services. These patterns vary considerably between rural areas.
5. Which French regions have the oldest populations?
Corsica, Nouvelle Aquitaine, Bourgogne Franche Comté, Brittany and Provence Alpes Côte d’Azur have relatively high shares of older residents, although the ranking depends on the age threshold used. INSEE’s 2026 estimates show that 33.2% of Corsica’s residents were aged 60 or older.
6. How does migration affect regional population growth?
Migration changes population totals directly. A region can grow despite more deaths than births if enough people move into it. Internal migration redistributes residents between French regions, while international migration can increase the national population as well.
7. What will France’s regional population distribution look like in 2050?
INSEE’s central projection series anticipates stronger demographic performance in parts of the south and west and weaker growth or decline in several central and northeastern regions. The outcome depends on fertility, mortality and migration assumptions, so projections should be read as scenarios rather than certainties.
