สรุป	Surname-based mobility analysis estimates how strongly social status is inherited across generations without linking a single parent to a single child. Developed by Gregory Clark, it exploits the fact that surnames cluster: certain names were borne disproportionately by elites, others by the poor. By tracking how over-represented or under-represented a surname group is among elites, university graduates, physicians, attorneys, the wealthy, across successive generations, one observes how fast that group's relative status regresses toward the population mean. The speed of regression yields an estimate of underlying intergenerational persistence, conventionally denoted b. Clark's striking and contested finding is that this group-level b is far higher, around 0.7 to 0.8, than the 0.3 to 0.5 typically found by conventional parent-child studies, implying that the deep, latent component of social status is far stickier than single-generation correlations suggest. The method extends mobility measurement into eras and places where individual linkage is impossible.	Quantitative prosopography studies a historical group by investigating the common characteristics of its members through a collective analysis of their lives. Rather than writing one biography, the prosopographer defines a population, members of a parliament, a senate, a profession, a religious order, and poses a uniform set of questions to each life: social origins, education, marriage and kin, offices held, wealth, career path. The answers, encoded as structured data, are then analysed statistically and, increasingly, as networks, mapping the kinship, patronage, and office-holding ties that bound the group together. Programmatically articulated by Lawrence Stone and rooted in the work of Namier on Parliament and Syme on the Roman aristocracy, the method turns scattered biographical detail into comparable variables and relational graphs. In its modern, database-driven form it joins large biographical datasets to network analysis and statistics, illuminating how elites recruited, reproduced, and governed.
