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.

Use it for GOOD -- never for EVIL
