"The argument is often made that immigrants have a stronger commitment to traditional family values than do native-born Americans. However, birth records show that about one-third of births to both groups are now to unmarried parents. Moreover, unmarried immigrants are significantly more likely than unmarried natives to give birth. Illegitimacy may be especially problematic for children of immigrants because they need strong families to adjust to life in America."
