Research shows that country of origin matters for speed and depth of immigrant assimilation but that there is considerable assimilation overall. Research finds that first generation immigrants from countries with less egalitarian gender cultures adopt gender values more similar to natives over time. According to one study, "this acculturation process is almost completed within one generational succession: The gender attitudes of second generation immigrants are difficult to distinguish from the attitudes of members of mainstream society. This holds also for children born to immigrants from very gender traditional cultures and for children born to less well integrated immigrant families." Similar results are found on a study of Turkish migrants to Western Europe. The assimilation on gender attitudes has been observed in education, as one study finds "that the female advantage in education observed among the majority population is usually present among second-generation immigrants."
