In this paper we describe and contrast the age and spatial structures of migration identified by data collected over one-year and five-year time intervals, by focusing, in particular, on the generation and distribution components of age- and origin-destination-specific migration flows. We...

In this paper we model the structures found in the level (generation) and allocation (distribution) components of age-specific and origin - destination-specific migration flows. For the examples, we examine the regional migration patterns in the USA for four periods: 1955 - 60, 1965 - 70, 1975 -...
