"With the passage of time, and especially following the emergence of the second generation, there was unmistakable evidence of assimilation among the descendants of early 20th century European immigrants. Acculturated through their attendance at American schools, the children of immigrants did not share the ambivalence of their immigrant parents. The second generation spoke fluent English and was eager to join the American mainstream. By all measures, including socio-economic status, residential mobility, and intermarriage, they left behind the ethnic world of their immigrant parents (Alba and Nee 2003; Lieberson 1980). By the 1950s, patterns of suburbanisation broke down ethnic neighborhoods and intermarriage became more common (Alba and Nee 2003; Lieberson and Waters 1988). Although it is widely assumed that immigrants in the Post-1965 Immigration Wave are less likely to assimilate than those who arrived in the early 20th century, there is growing evidence that the new immigrants, especially their children, are doing remarkably well (Alba and Nee 2003; Kasinitz et al. 2008). On average, second generation immigrants are less likely to drop out of high school and more likely to attend college than the average native born American (Hirschman 2001; White and Glick 2009). Intermarriage is also common: recent research estimates that one-third to one-half of second generation Hispanics and Asians marry outside of their community (Duncan and Trejo 2007; Min and Kim 2009). The children of contemporary immigrants are on track for assimilation and upward mobility at about the same pace as the descendants of earlier waves of immigration from Europe."
