What is NAPP?
The North Atlantic Population Project (NAPP), created by the Minnesota Population Center, University of Minnesota in collaboration with the University of Ottawa, Université de Montréal, University of Essex, Statistics Iceland, National Archives of Sweden, Stockholms stadsarkiv, Umeå University, University of Bergen, and the University of Tromsø. NAPP is a machine-readable database of the complete censuses of Canada (1881), Great Britain (1881), Iceland (1870, 1880, 1901), Norway (1865, 1900), Sweden (1900), and the United States (1880). These data have only recently become available for social science research. The nine censuses collectively comprise our richest source of quantitative information on the population of the North Atlantic world in the late nineteenth century. To allow the comparative analysis of human behavior across these countries, the NAPP collaborators have harmonized the record layouts, coding schemes and documentation for the different censuses. NAPP assigns uniform codes across all the censuses and brings relevant documentation into a coherent form to facilitate analysis of social and economic change. NAPP data is compatible with the existing IPUMS series of U.S. census samples, and is the foundation for a long-term collaborative enterprise to reconstruct the population of this region from the mid-nineteenth century to the present.
