Social mobility in multiple generations.

Despite the dominance of a two-generation approach to the study of intergenerational social mobility, multigenerational influences that link the characteristics of kin across three or more generations may be important in some populations. These effects include direct net effects of grandparents' socioeconomic characteristics on grandchildren, the effects of even more remote generations, the effects of family characteristics that bring extreme advantage or disadvantage at points in the past that are not uniformly tied to any specific past generation, a variety of demographic effects that both reweight socioeconomic distributions in successive generations and also incorporate multigenerational effects on demographic behavior itself, heterogeneous multigenerational effects in populations that contain more than one social mobility regime, and long-run multigenerational effects that result from mobility-fertility interactions in population dynamics. Genealogical data from the Qing Dynasty Imperial Lineage and from population registry data for Liaoning, China over the past several centuries provide illustrations of all of these types of multigenerational effects. Multigenerational influence is much more multi-faceted than previous speculations and empirical investigations have implied. [ABSTRACT FROM AUTHOR]
