From 1984 to 1999, SIDeS published 31 printed issues of the Bollettino di Demografia Storica. The journal disseminated the results of research relating to demographic history in the medieval, modern and contemporary ages, proposing contributions regarding the critical examination of sources and the application of new quantitative methods. The themes of the published articles embraced more typical demographic topics, such as those relating to the discussion of archival sources, demographic structures and the territorial distribution of the population, demographic evolution, fertility, reproductive behaviour, marriage and mortality. Other studies included interdisciplinary issues, such as migration, epidemics, abandoned childhood, families, minorities, relationships between demographic variables and other socioeconomic factors.
