Historical demography
Historical demography is the quantitative study of human population in the past. It is concerned with population size, with the three basic components of population change--fertility, mortality, and migration, and with population characteristics related to those components, such as marriage, socioeconomic status, and the configuration of families.Development of techniques
Historical analysis has played a central role in the study 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 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 development of massive new population data collections, including the Demographic Data Base in Umeå, Sweden, the Historical Sample of the Netherlands, and the Integrated Public Use Microdata Series.
According to Willigan and Lynch, the main sources used by demographic historians include archaeological methods, parish registers starting about 1500 in Europe, civil registration records, enumerations, national census beginning about 1800, genealogies and family reconstruction studies, population registers, and organizational and institutional records. Statistical methods have included model life tables, time series analysis, event history analysis, causal model building and hypothesis testing, As well as theories of the demographic transition and the epidemiological transition.Techniques
