Abstract
In this article, we report analyses of the effects of fertility and mortality trends on the mutual exposure of grandparents and grandchildren and their consequences for multigenerational processes of social mobility in the United States from 1900 to 2010. Using historical vital statistics and stable population models, we report systematic analyses of grandparent-grandchild exposures from both prospective (grandparent) and retrospective (grandchild) perspectives. We also estimate exposure levels and trends specific to education levels of grandparents and grandchildren and decompose the overall trend into the effect of changing mortality, fertility level, and fertility timing. We show that changes in mutual exposure of grandparent and grandchild generations may have contributed to an increasing association between grandparents’ and grandchildren’s educational attainments.

Notes
Parents’ education refers to father’s years of schooling if grandparents are from the paternal side; otherwise, it refers to mother’s years of schooling.
Haines (1989) did not provide separate estimates for 1900 and 1910. We use the midpoint method to estimate TFR in 1900 and 1910.
Specifically, we estimate m(x) ∝ N(Ar, σ2), within the range of x ∈ [15,45] for woman and [15,60] for men. We assume that the mean age of childbearing (Ar) and the variance of age of childbearing (σ2) are the same for men and women given that the Census Bureau provides these estimates only for females. Specifically, because \( GRR={\int}_{\upalpha}^{\upbeta}m(x) dx \), we estimate m(x) = GRR ∙ ψ(Ar, σ2, α, β; x), where \( \uppsi \left({A}_r,{\upsigma}^2,\upalpha, \upbeta; x\right)=\frac{\upphi \left({A}_r,{\upsigma}^2;x\right)}{\Phi \left({A}_r,{\upsigma}^2;\upbeta \right)-\Phi \left({A}_r,{\upsigma}^2;\upalpha \right)} \) if α < x < β, and ϕ(⋅) and Φ(⋅) refer to the probability density function and the cumulative distribution function of a normal distribution, respectively.
Specifically, the relationship of the intrinsic growth rate and the age-specific fertility and mortality schedules follows \( {\int}_0^t{e}^{- rx}l(x)m(x) dx=1 \), where r is the intrinsic growth rate, and t is the maximum age in the population.
We assume that the GRR for the first education group in 1900 is proportional to the GRR for the second education group in 1920 with a constant c, where c = GRR1900 / ∑iGRRedu = i ∣ year = 1920 ∙ P(edu = i | year = 1900).
The estimated fertility effect becomes larger when we fix mortality at a lower level (e.g., the level of 1950) than that shown in Fig. 2, panel b. Again, this implies that the effects of fertility and mortality are not additive; instead, their interaction affects the trend in exposure.
It is also possible to obtain estimates for grandchildren whose grandparents differ in their levels of education.
