Estimació matemàtica de la població de la Corona d’Aragó

The demographic data of a territory, or society, can give valuable information of an analysed group of interest, but appropriate demographic data must be available. This is not the case of the Crown of Aragon in the medieval period. Censuses or other statistical data are limited. They do not allow us to do population estimates for the whole period of the Late Middle Ages. The objective of this paper is to present a mathematical tool, interpolation, which allows to estimate the late-medieval population of the Crown of Aragon from fiscal censuses and published projections and estimates.
