The nineteenth-century American family experienced tremendous demographic, economic, and institutional changes. By using birth order effects as a proxy for family environment, and linked census data on men born between 1835 and 1910, we study how the family's role in human capital production...

Efforts to document long-term trends in socioeconomic mobility in the United States have been hindered by the lack of large, representative datasets that include information linking parents to their adult children. This problem has been especially acute for women, who are more difficult to link...

The Census Tree is the largest-ever database of record links among the historical U.S. censuses, with over 700 million links for people living in the United States between 1850 and 1940. These high-quality links allow researchers in the social sciences and other disciplines to construct a...

Explanations for the West's escape from premature mortality have focused on chronic malnutrition or income and on public health or state capacity. We argue that by ignoring the multigenerational effects of variance in ancestors' harvests, we are underestimating the contribution of modern...

We compile, transcribe, and standardize historical records for 2.5 million students at 65 elite (private and public) U.S. colleges. By combining these data with more recent survey and administrative data, we assemble the largest dataset on the socioeconomic backgrounds of students at American...

We explore how socio-economic background shapes academia, collecting the largest dataset of U.S. academics' backgrounds and research output. Individuals from poorer backgrounds have been severely underrepresented for seven decades, especially in humanities and elite universities. Father's...

We link census records for millions of farm children to identify owner-operators of the family farm in adulthood, providing the first population-level evidence on intergenerational farm transfers. Using our panel of U.S. census data from 1900 to 1940, our analysis supports the primogeniture...

A key challenge for research on many questions in the social sciences is that it is difficult to link historical records in a way that allows investigators to observe people at different points in their life or across generations. In this paper, we develop a new approach that relies on millions...

This paper studies how exclusive social groups shape upward mobility, and whether interactions between low- and high-status peers can integrate the top rungs of the economic and social ladder. Our setting is Harvard in the 1920s and 1930s, where new groups of students arriving on campus...

Using recent innovations in linking historical U.S. Census data, we study the economic impacts of immigration on natives, including their geographic migration response. We find that the arrival of foreign immigrants significantly increases both native out-migration and in-migration. Accounting...
