What are the sources of NAPP data?
Creation of complete count census databases for research builds on the existing samples of historical censuses in all six countries. Complete count 1880/81 censuses of the United States, Great Britain, and Canada were transcribed in the 1980s and 1990s by the Church of Latter-Day Saints (LDS) for genealogical purposes. LDS donated the data for academic use in exchange for cleaning and enhancing the data. The Norwegian, Swedish, Icelandic, and other Canadian censuses were digitized by academic researchers and archivists.
Our research and data partners in the participating NAPP countries are listed here. The Minnesota Population Center also has agreements with the LDS, who allow us to freely distribute the data to academic researchers in exchange for cleaning and enhancing the data.
