A separation, a growing family, retirement or the desire for a better quality of life: for many reasons, many Ile-de-France residents settle in the provinces and create significant life gaps with their new neighbours, Insee revealed on Thursday.
In 2018, the reference year of the study, 101,000 Ile-de-France residents migrated to the province (including the DOM), the equivalent of a city like Boulogne-Billancourt (Hauts-de-Seine), underlined François Dubujet, head of demographic and social studies at Insee Île-de-France, during a press conference.
However, the Ile-de-France population continues to grow, he notes, due to the natural demographic balance.
These migrant Ile-de-France residents have on average a 15% higher standard of living than the provincials of the same age with whom they meet when they settle, with significant disparities on the territory.
In Lyon, this gap reaches 27%, 33% in Nantes, 18% in Marseille and 13% in Orleans, noted Mr. Dubujet.
And Ile-de-France residents over 60 - mostly retirees - who migrate to the province have on average a 28% higher standard of living than their neighbors.
Ile-de-France residents who leave their region already enjoy a higher standard of living than those who stay, with a median income of 2,230 euros against 2,050 euros.
When they move to the provinces, this income drops to 2.
Lyon, the most popular city
These Ile-de-France residents who leave their region of origin are mostly couples (47%), single people and are under 40 (45%).
They were 30% to live in a house against 46% after moving to the provinces.
The living area of their residence also increases, from an average of 62m² to 80m².
The provincials, in comparison, are 62% to live in a house and live in 86m² on average.
The first city in France attracting Ile-de-France residents of all age groups is Lyon, followed by Toulouse, Nantes, Bordeaux and Marseille.
Concerning the reference year of the study made public on Thursday, "
2018, it may seem old but the data is structural
", insisted on specifying François Dubujet, acknowledging "
that the health crisis may have had an impact on the mobility of Ile-de-France residents
” in terms of volume of flows.
