Metropolitan and nonmetropolitan population trends in Canada, 1966-1982.

"The purpose of this paper is to discuss the recent dynamics of spatial population distribution in Canada. More specifically, we examine the effect of interregional migration flows on growth and decline in Canadian regions. Our analysis is based on an annual series of aggregate migration at the metropolitan level, which supplements the information available in existing census-year studies and further clarifies the impact of international migrants on recent spatial population trends in Canada."

An analysis of migratory systems: 1. Theory.

This is the first of a planned series of three papers in which the authors attempt to combine evolutionary migration models with stochastic utility theory. This first paper deals with the evolution of migratory systems. Such systems are first defined, and the foundations upon which their evolution is based are described. The paper concludes with a discussion of disequilibrium, which is central to the series. "Disequilibrium is related to the concept of a steady state, the existence of which is established for nonlinear migratory systems of the type discussed here."

An analysis of migratory systems: 2. Operational framework.

"This is the second in a series of three interrelated papers which aim to combine evolutionary migration models with stochastic utility theory. The first paper dealt with migratory dynamics. Here the details are given of a choice model, established by McFadden, which can be used in conjunction with migratory dynamics thus providing an explicit link between the macroproperties of the population system and human behaviour. First, the structure of transition probabilities is derived under a two-level decision to migrate. An argument is then given about the empirical form of these probabilities, and the discussion closes with a method which can be used for their maximum likelihood estimation."
