Our main findings: - lower income, no capital income and unemployment are associated with higher risks of leaving Paris. - social housing plays an important role: it greatly increases the chances to stay put in Paris, especially where the local market is under higher pressure.

- less affluent households go farther away from the city centre when they move. - poverty is particularly discriminating for single-parent families, - beneficiaries with moderate income (i.e. the lower middle class ) go the farthest away.
