Two social changes are cited as particularly important to the projection of college enrollment trends. One is the rising educational attainment of the parents of future potential college attenders; the other is the fact that declines in fertility accompany declines in average family size. Overall, the illustration in this paper suggests that the decline in enrollment due to the decline in birthrates may be cushioned by increases in the proportion of a birth cohort attending college due to rising parental education and declining parity. How much of that cushion will be destroyed due to declining relative wages of college attenders operating through changing cohort parameters is not clear. The results of the analysis are interpreted to mean that there are some farily substantial contemporary sociodemographic trends that influence educational attainment and are rather separate from changes in the relative wages of the more highly educated. In the past these sociodemographic changes have accounted for the majority of the change in college attendance and their future change is likely to impact attendance fairly considerably. (Author/LBH)
