Projecting interregional migration balances within a multiregional cohort - component framework

An examination of the projection output derived from fixed-rate and variable-rate interregional migration assumptions reveals the difficulty with which an acceptable range of migration scenarios is developed for use in Canadian population projections. The development of acceptable migration assumptions is limited by the choice of projection methodology, the requirements of projections within the present context, and the demographic characteristics of Canada's regions. In order to overcome these limitations, a technique for controlling projected interregional migration balances within a cohort - component framework is proposed. This approach improves the utility of the interregional projection methodology and meets all the requirements for population projections in the present context.
