Historical analysis has played a central role in the explore of population, from Thomas Malthus in the eighteenth century to major twentieth-century demographers such as Ansley Coale and Samuel H. Preston. The French historian Louis Henry 1911-1991 was chiefly responsible for the development of historical demography as a distinct subfield of demography. In recent years, new research in historical demography has proliferated owing to the developing of massive new population data collections, including the Demographic Data Base in Umeå, Sweden, the Historical sample of the Netherlands, and the Integrated Public ownership Microdata Series IPUMS.
