The Night of Solidarity is an operation that counts the number of homeless people within a territory on a given night.
The aim is to gain a better understanding of the profiles and needs of people with no housing or overnight shelter solutions so that public policies can be adapted to respond to them.
The first Night of Solidarity took place in 2018 in the territory of Paris. Since then, the procedure has been carried out by the Paris City Council each year.
In 2022, on the night of 20th to 21st January, counting was extended to the Grand Paris Metropolis, initially in 9 voluntary municipal communes as a metropolitan experiment. More municipal communes will be involved as from the Night of Solidarity in January 2023.
The Paris Urbanism Agency (Apur) provides the City of Paris, the Grand Paris Metropolis and participating municipal communes with methodological assistance. Apur is also responsible for exploiting the data and analysing the responses to a questionnaire in conjunction with the Scientific Committee of the Night of Solidarity. Each year, analysis reports summarising all the results are made and distributed.
All the documents produced from the exploitation of results in Paris and the Grand Paris Metropolis can be found on this page, in chronological order.
