CNAF is not a competitive employer.

French public service is essentially split in two: the State, and the various "Social Security" bodies which manages most of the welfare system (among them, the Caisse Nationale des Allocations Familiales which manages part of social & family welfare).

The "State" side has a very competitive track for stats/econ/ML employees, namely the national statistics office members (INSEE). As the name does _not_ indicate, they work everywhere in the government, not just at INSEE.

So if you're good at stats and in public service, the odds you end up in the CNAF team instead of the statistiscal office of the Social Ministry is about zero.

Hence SAS. Hence logit. And so forth.
