When one generation attains educational advantage, the next generation reaps significant benefits in its own educational, financial, cultural, marital, health, and occupational prospects (e.g., Anderson, Sheppard, and Monden 2018; Axinn and Thornton 1992; Dubow, Boxer, and Huesmann 2009; Erola, Jalonen, and Lehti 2016; Kraaykamp and Van Eijck 2010; Ross and Mirowsky 2011). The strength of the parent-child correlation in life chances is now widely recognized. However, for many decades scholars suggested that the intergenerational transmission of life chances did not extend beyond the parent-child pair (Song et al. 2020). In this account, known as the Markovian model, the grandparent’s outcomes were correlated with the focal child’s but in ways that were attributable to their common association with the parent’s outcomes (e.g., Warren and Hauser 1997). Mare’s (2011) influential Population Association of America (PAA) presidential address led researchers to reexamine whether intergenerational effects reach beyond this generational span. The resulting research has consistently revealed that grandparents may exert direct and indirect effects on the educational outcomes of their grandchildren through a variety of non-Markovian mechanisms. Findings from the past decade of research raise the question of whether the intergenerational reach of socioeconomic status may include great-grandparents as well.
