Demographic Trends in the Greater Paris - Grand Paris Metropolis -

On the 1st January 2022, 7,115,576 people were living in Grand Paris Metropolis. Between 2016 and 2022, the population grew on an annual average of +0.2%, a slower rate than during the previous period (0.3%). The growth of the population was mainly found in areas within Seine-Saint-Denis. Other territories to the south and south-east of Paris, such as Grand-Orly Seine Bièvre (T12) and Grand Paris Sud Est Avenir (T11) also contributed to the rise in the population, as did Boucle Nord de Seine (T5) lying north of Hauts-de-Seine. This dynamic was exclusively linked to the rate of natural increase (RNI), even though it slightly declined over the period. The surplus of births over deaths thus resulted in an average rise of 57,150 people per year in Grand Paris Metropolis, compared with 66,300 per year over the previous period. The migratory balance, that is the difference between arrivals and departures, remained in deficit (-42,300 people on average per year, that is -0.6% between 2016-2021).

In addition to the demographic factors, the growth of the populations in the territory was also due to reasons linked to developments in the housing stock and the occupation of housing units. In Grand Paris Metropolis, the number of principal residences (housing occupied at least 6 months per year), increased but at a slower rate than the total number of housing units (+173,700 housing units between 2015 and 2021 of which only +100,500 were principal residences). At the same time, the average number of people per occupied housing unit fell from 2.20 in 2015 to 2.16 in 2021, reflecting the drop in births and the ageing of the population. These two factors contributed to a slowing down of the population growth observed during the period.

In Paris, the correlation between the development of population growth and the development of the housing stock was particularly marked. The rise in unoccupied housing units which group together second homes, occasional accommodation and unoccupied housing had the impact of reducing the population. The more recent reduction in the size of households has also played an increasingly important role in the fall of the population over the last few years. On 1st January 2022, Paris housed 2,113,705 people, an annual, average reduction of 12,800 inhabitants per year during the 2016-2022 period. This was accompanied by the ageing of the population, also found throughout the metropolitan area. By 2040, according to Insee's most recent forecasts, almost one in five inhabitants of Grand Paris Metropolis will be 65 years of age or over.
