The American National Election Studies (ANES) produces data on voting, public opinion, and political participation to serve the research needs of social scientists, teachers, students, policy makers and journalists who want to better understand the theoretical and empirical foundations of national election outcomes. The center releases pre- and post-election waves and has aggregated a contiguous file across the entire timespan of the survey (the Time Series Cumulative file). | Person-level

The three major data infrastructure projects of the Minnesota Population center include: IPUMS-International; an integrated series of census microdata samples from 1960 to the present; IPUMS-USA, an integrated series of representative samples drawn from the U.S. censuses of the period from 1850 to 2000; and IPUMS-USA, which also includes American Community Survey (ACS) data from 2000 to 2005. IPUMS-CPS provides integrated data and documentation from the March Current Population Survey (CPS) from 1962 to 2006. Other datasets include the North Atlantic Population Project, the National Historical Geographic Information System, and the Integrated Health Interview Series. | Person-level
