International Census Data for Social Science Research

The North Atlantic Population Project (NAPP) harmonizes and disseminates nineteenth and early twentieth century census microdata. The collection includes data from Canada, Denmark, Great Britain, Germany, Iceland, Norway, Sweden, and the United States for the period 1703 to 1911, may of which are full count census files. These census datasets contain basic demographic information, along with additional information on religion, occupation, industry, schooling, and household characteristics.

NAPP is a collaborative project carried out at the Minnesota Population Center, University of Minnesota, in conjunction with several international partners: University of Ottawa, Université de Montréal, Danish National Archives, University of Essex, National Archives of Iceland, Statistics Iceland, University of Iceland, National Archives of Sweden, Stockholms stadsarkiv, Umeå University, University of Bergen, University of Tromsø, National Archives in Oslo, Max Planck Institute for Demographic Research, University of Rostock, and the Landeshauptarchiv (State Main Archive) Schwerin. The material currently in the NAPP database is the foundation for a long-run collaborative enterprise to reconstruct the population of the North Atlantic world from the mid-nineteenth century to the present.
