In this article, we use an econometric model to forecast human capital levels and skilled migration rates in all the regions of the world. Given the trends in educational attainment, our simulations reveal that the average world brain drain should decrease in the following decades, at least if receiving countries keep their immigration policy unchanged. If France conducts a selective migration policy as in Canada, the stock of immigrants will decrease by about 180 000 individuals until 2050 and the proportion of skilled migrants will reach 60 %. This policy would induce a significant increase in the brain drain from North Africa, sub-Saharan Africa, oecd countries and, to a lower extent, South Asia. Classification JEL: F22, J61
