The Census Tree: Replication Files for 1900-1910

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 links allow researchers to construct a longitudinal dataset that is highly representative of the population, and that includes women, Black Americans, and other under-represented populations at unprecedented rates. <br>This project contains the files necessary to closely replicate the links between the 1900 and 1910 censuses.
