By 2020, MPC will make freely available to researchers worldwide 100% count U.S. Census microdata through 1940. This dataset will include over 650 million individual-level (1850-1940) and 7.5 million household-level records (1790-1840).

“The importance of this massive donation of census data would be difficult to overstate,” says MPC Director Steve Ruggles. “This is one of the largest-scale data-entry efforts ever undertaken.”
