Up to the late 1970's the Sex College Attainment Ratio (SCAR), or ratio of college attainment between men and women, was about 1.6. Assortative mating within education groups in marriages is strong enough in the United States to prevent accounting for the SCAR feature based on males' higher earnings. We document the puzzling nature of the SCAR, and we explore various theories to account for it. Our main finding is that if parents' well-being is affected by the number of grandchildren, gender differences in the steepness of the negative relation between educational attainment and number of children provides the best theory to understand the SCAR.
