Census Tree Project
We are creating a Census Tree that will link the 188 million people that lived in the United States between 1900 and 1940 across each of the census records for these years they appear in and connect each person to all of their one-hop relatives (parents, siblings, spouses, and children). The Census Tree will provide the largest longitudinal data set ever created in the United States and will open up many opportunities for research in economics, demography, sociology, and public health. Here is a link to the paper and slides about the project that we recently presented in Oslo. We are working with several groups on this project including Kasey Buckles, Steve Ruggles, Cathy Fitch, and Jonas Helgertz.
