Contributions 2011-2016 % 2016-2022 %
Total change 113 13,6 42 4,3

due to the demographic effect 79 9,5 –9 –0,9
  • Note: The change in the number of households (and therefore in the number of main residences) can be broken down into two effects: the "household size effect" and the "demographic effect." Indeed, a decrease in average household size leads to an increased housing need, even if the population remains stable. The remaining part of the change is referred to as the demographic effect. These effects can be either positive or negative.
