grants. These figures are not really comparable since our projections refer to educational distributions 30 to 40 years in the future rather than the current levels. Average educational attainment in the U.S. has been rising and it is reasonable to assume that significantly more than 52 percent of the great-grandchildren of nonimmigrants will attain more than a high school education. Indeed, our analysis of the intergenerational educational matrices for the nonimmigrant population indicates a long-run educational distribution in which 72 percent of the population attains more than a high school education.

Tables 7.B1 to 7.B3 present data on the net present values for immigrants, by age of arrival and for native-born residents, in the third and later generations, at current ages, for various alternative assumptions.
