Two scenarios leading up to 2035

The evolution of the housing stock and its occupants in Île-de-France, greatly influences the growth of the population and its distribution within the Region. When considering recent trends, both in the renewal of the housing stock and the ways in which it is occupied, two scenarios have emerged, characterised by the volume of new construction, that can be put forward.

In the first, 50,000 housing units will be built on average per year. By 2035, the proportion of unoccupied housing will rise from 10% to 12%. The size of households will decrease, particularly in the outer suburbs -Grande Couronne-. The Region will have 5,7 million households and 13,1 million inhabitants. 

In the second scenario, called “Grand Paris Law -loi Grand Paris-”, 70,000 housing units will be built each year. By 2035, the population of Île-de-France will therefore be over 400,000 higher than in the first scenario. This increase will exceed any growth in the population over the last 40 years. Unoccupied housing units, the falling number of household members and the concentration of the population in the inner ring of suburbs -Petite Couronne- will also be accentuated.
