Trends in BMI values are estimated by centiles of the US adult population by birth cohorts 1886-1986 stratified by ethnicity. The highest centile increased by some 18 to 22 units in the course of the century while the lowest ones increased by merely 1 to 3 units. Hence, the BMI distribution...

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...

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...

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...
