SPATIAL POPULATION DYNAMICS [PDF]
Papers in Regional Science, 1976 This paper examines the relationships between natural increase (births minus deaths) and net migration (in-migrants minus out-migrants) in regional populations and identifies and clarifies some of the fundamental population dynamics involved. First the authors consider several well-defined regularities of fertility mortality and migration schedules ...
