The Valency Of The Natural And Social Components As Determinants Of A Population’s Future Development

Abstract

The relation which ties the sociodemographic phenomena to the reference population of a given territory, is the representative essence of every social organism. Hence, there is the statistical need to get as many data as possible, as they become essential when you must make a decision that will influence the future choices of any human aggregation. The goal of the present contribution is to make population projections of the city of Bari (South Italy), studied by sex and age, aimed at knowing the future social effects through the analysis of the natural components (fecundity, mortality) and the social ones (migrations) of the studied population.
