ABSTRACT
Demographic multipliers are used to predict the municipal and school populations that will result from new housing development. When the number, type and configuration of incoming housing units and therefore the magnitude of the new population are known, estimates of public service requirements and costs can easily be projected. The principal feature that distinguishes condominiums from other multifamily housing types is their legal form of ownership. Those who reside in single family attached or multifamily condominium units individually own, rather than rent, their units. The temporal variation of demographic multipliers focuses on two basic issues: the accuracy over time of projections made on the basis of a given set of multipliers, and the validity of multipliers calculated for the current period for longer periods of time. It is important that the practitioner understand the difference between a public school attender and a school-age child and further realize that in the past demographic multipliers have been provided for each.
