Demographic Systems of Medieval Italy (6th–15th century AD)

Abstract

AbstractIn this article, we bring together a variety of studies, both old and new, to examine continuity and change in population dynamics in Italy during the medieval millennium (476–1492 AD). Though the available data are often sporadic and should be interpreted with great caution, it is possible to clarify certain dynamics, which can be useful for guiding future research. First, population fluctuations were not impacted by migration into or out of Italy. Second, medieval Italy was characterized by a high‐pressure demographic regime: e0 was around 20 years, with high adult mortality, and the birth rate was around 50 per mill. Third, despite high mortality, the Italian population grew (+50 percent) from the ninth century to 1347, mainly—but not exclusively—due to the absence of plague. Fourth, the stagnant population of the periods between the sixth and the eighth centuries and the 14th and 16th centuries was determined by the recurrent outbreaks of plague. Fifth, the population stagnation during the first and the last medieval centuries is also partly related to the increase in age at first marriage, while the demographic growth between the ninth and mid‐14th century is possibly connected to the decrease in age at first marriage among women. Sixth, the vitality of the medieval Italian population was partly ensured by a high rate of remarriage among widows. Seventh, data on statures show that mortality levels were determined by epidemic factors, rather than living standards. Finally, when the plague ceased in Europe in the middle of the Early Modern Age, adult survival was significantly higher than in the ancient and medieval centuries, despite the fact that neither hygienic‐sanitary nor epidemiological conditions, and certainly not nutrition, were better than in the centuries preceding the Black Death.
