This paper provides an overview of recent empirical and methodological advances in the study of historical intergenerational mobility trends, with a focus on key measurement challenges. These advances are made possible by the recent digitization of historical censuses and new methods of historical record-linking, which have enabled researchers to create large historical samples of parent-child links. We identify three main findings. First, absolute mobility increased in the decades leading up to 1940 but has since declined, both in the US and other industrial countries. Second, recent studies on relative mobility question the classic narrative that the US has transitioned from a âland of opportunityâ in the 19th century to a less mobile society today, suggesting that mobility was not as high in the past. However, estimates of relative mobility are sensitive to choices regarding sample selection and measurement. Third, we explore mechanisms underlying shifts in intergenerational mobility over time, including geographic mobility, wealth shocks, educational attainment, locational effects, and the transmission of parent-specific human capital. We conclude by suggesting avenues for future research.
