According to Insee: "In Paris, the population continues to decline, and has done so for the past nine years."
The reason for this tendency is clear: "Departures from the capital are motivated in particular by the high cost of housing, the reduced supply of large homes for families and the search for another way of life," the institute says.

However, with 48,520 residents, the upmarket 7th arrondissement has seen nearly 7,000 former residents pack up and leave – the most marked decline in the Paris region, down by 12.6 percent.
District mayor Rachida Dati has underlined that her arrondissement is plagued by traffic problems and building work that slows down the bus routes – "Paris is always dirtier, more insecure.
"For years, I have been asking Paris City Hall to create intermediate housing to enable families to stay in the 7th arrondissement. Finally, I fear that the increase in property tax decided by the city will also accelerate the departure of those who used to own their properties," Dati added.
