Réflexions sur les méthodes de projection en milieu urbain — nécessité de la prise en compte du logement
Geographia Polonica (1993) vol. 61, pp. 19-32
Projections concerning town or district populations need to take dwellingsinto account, unlike national or regional projections where this variable doesn't come intoplay. The first reason for this necessity is obvious: the disappearance or construction ofdwelling units automatically brings automatically about a diminishing or increasing ofpopulation. The second reason is more subtle. If a population is young and increasing,steadiness of the dwelling number leads to out-migration of the new households built inthe place. On the contrary, an older and decreasing population releases dwelling unitsand leads thus to immigrations. This communication shows how it is possible, practically,to integrate this dwelling constraint into the projection model.
