This paper addresses the question of how to formally represent the spatial structure of an observed origin-destination-specific pattern of interregional migration flows. Such a representation allows an analyst to compare the spatial structures of different migration regimes and contrast their...

The paper presents probability models to recover information on migration flows from incomplete data. Models are used to predict migration and to combine data from different sources. The parameters of the model are estimated from the data by the maximum likelihood method. If data are incomplete,...

Multi-state models describe the transitions people experience as life unfolds. The transition probabilities depend on sex, age, and attributes of the person and the context. Empirical evidence suggests that attributes that cannot be measured directly may at most be inferred from a long list of...

The regional distribution of the foreign-born population is determined by two principal migration processes: internal and external migration, modified, of course, by the impacts of mortality. (Since the fertility of the U.S. foreign-borns increases only the population of native-borns, it only...
