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...

Beginning with the 2010 decennial census, the U.S. Census Bureau plans to drop its long-form questionnaire and to replace it with the American Community Survey (ACS). The resulting absence of the larger sample provided by the census count will complicate the measurement and analysis of internal...

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...

Observed schedules of migration rates exhibit strong regularities in age patterns. These regularities may be captured and represented by a mathematical expression known as the multiexponential model migration schedule. Fitting this function to empirical data requires non-linear regression...
