In collaboration with our partners at Ancestry.com, the Minnesota Population Center has released new historical census data through IPUMS-USA. Full count data for 1790-1840 is available via IPUMS-USA as household-level and county-level datasets* for each decennial census year and for the combined years, 1790-1840.

How Historical Data Become Public
An enormous amount of information about the characteristics and activities of ordinary people is just waiting to make its debut for researchers to analyze — two billion people and their households, spanning over 100 countries, from 1703 to the present day. All these data will be available for computer analysis by the general public, for free, by 2018.
The 2015 IPUMS Research Award Honorees
The Minnesota Population Center (MPC) is excited to announce the winners of its annual IPUMS Research Awards. The awards honor the best published research and best self-nominated graduate student papers of 2015 that used MPC data to advance or deepen our understanding of social and demographic processes.
Family and Household Context with IPUMS Data
Family-member characteristics are often related to individual outcomes. The IPUMS data extract system makes it easy for you to include in your datasets variables that describe other household members, such as age of mother, occupation of father, or educational attainment of spouse.
Counting—and Redefining—the Cost of War
Associate Professor of History and MPC Faculty Member J. David Hacker made headlines in 2011 when he published a groundbreaking study of the total number of U.S. Civil War dead. Hacker argued that the widely-accepted figure of 620,000 was far too low. Using IPUMS, Hacker showed that the number of dead was at least 750,000—if not more. His article, “A Census-Based Count of the Civil War,” published in Civil War History, was introduced by the editors in the issue as “among the most consequential pieces ever to appear in this journal’s pages.”
Few demographic historians expect attention from mainstream press when they publish their research, but Hacker’s study attracted national interest, including interviews with the New York Times and National Public Radio.
New Frontiers in Big Data
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 microdata represents the fruition of longstanding collaborations between MPC and the nation’s two largest genealogical organizations—Ancestry.com and FamilySearch—to leverage genealogical data for scientific purposes.
“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.”
