Supplementary data for: The Evolution of Black-White Differences in Occupational Mobility Across Post-Civil War America

<br>We examine long-run differences in intergenerational occupational mobility between Black and White Americans using linked censuses and survey data from 1850 to 2021. We document two main results. First, shifts in mobility dynamics, most notably for the 1940--1950 cohort, reshaped occupational structures and reduced racial segregation. Second, new measures of intergenerational persistence reveal both <i>bottlenecks</i> and the enduring <i>memory</i> in the mobility system, offering new perspectives on the role of mobility in explaining the lack of convergence in Black-White occupational outcomes.
