I'm not sure if there are studies for even longer periods of time, there are general employment numbers for foreigners and natives respectively (but then that would include work migrants etc, though half of those are unemployed after a few years too, it is an easy way to buy a visa). I'm not sure that I would count 1 hour a week as working to be honest. It does not count as working for EU perspectives, unless you are charging massively for that one hour. I'm curious as to how many years you think it takes to "settle down in one place" and what you mean by that. I interpret it as making a home, but maybe you mean something different? Again 8 years allow for a long time to learn the language (which should only take 1 year to learn enough to work, or 2 to learn enough to study at university) and possibly get some training. A large factor in the massive unemployment numbers is the fact that a lot of our refugees come from countries in which women are not allowed to work outside of the home.
Do you not understand what it means to account for socioeconomic factors?
