Saccording to the latest figures from INSEE, Ile-de-France officially has 12,380,964 inhabitants (reference population as of 1is January 2022). That is 263,832 more in six years, for an average annual increase of 0.36%, slightly higher than the national trend (+ 0.35%). Ile-de-France remains, by far, the most populated region of the country, which now officially has 67,760,573 inhabitants (excluding Mayotte).
The demographic growth of Ile-de-France is still based solely on the predominance of births over deaths. A natural balance which generates an average annual increase in the population of 0.77%. Net migration (ratio between arrivals and departures in the region) is still in deficit (-0.41% per year), slowing down demographic growth in the Ile-de-France region. This demographic growth is observed in all departments of the region, with the exception, once again, of Paris. If the capital remains the most populated territory in Ile-de-France, its population increased from 2,190,327 inhabitants in 2016 to 2,113,705 inhabitants in 2022 (- 0.59% on average per year). A loss of inhabitants which is explained by a significant migratory deficit (- 1.18% per year) – due in part to the cost of housing – insufficiently compensated by the share of the natural balance (+ 0.58% per year).
This phenomenon of migratory deficit affects all the Ile-de-France departments with the exception of Seine-et-Marne (+ 0.02%). Departments which, unlike Paris, can count on compensation of the natural balance. Seine-Saint-Denis in particular which, with 1,681,725 inhabitants, saw its population increase by 0.76% each year on average between 2016 and 2022, the largest demographic growth in the region. And this, thanks to a natural balance which still asserts itself as the largest in the region (+ 1.14% per year), much higher than the deficit in net migration (- 0.38%). After Paris and Seine-Saint-Denis, Hauts-de-Seine remains the third most populated territory in Ile-de-France with 1,647,435 inhabitants. And this, although the department is the one which has gained the least (+ 0.45% per year), tied with the department of Yvelines which remains the most populated in the outer suburbs (1,470,778 inhabitants).
In the inner suburbs, where the population increased by an average of 0.58% per year between 2016 and 2022, Val-de-Marne saw its population increase by 0.49% per year to reach 1,419,531 inhabitants. . While in the greater suburbs, where the population has grown on average by 0.55% per year, Val-d'Oise (1,270,845 inhabitants) and Seine-et-Marne (1,452,399 inhabitants) are the departments which show the greatest demographic growth, respectively + 0.66% and + 0.64 per year on average, higher than the average annual progression of 0.48% of Essonne (1,324,546 inhabitants).
