Spatial-dynamic population systems:  analysis and projection.
"In this paper a set of more-detailed multiregional population accounts is proposed to specify more realistically the exposure time of populations at risk for various components of population change.  The concepts of population-time at risk and forward demographic rates based on the initial population are discussed.  The relations of the forward demographic rates defined in this paper with the occurrence-exposure demographic rates are discussed.  A more precise and straightforward multiregional population model is developed on the basis of forward demographic rates.  The model is also expressed in the familiar matrix form of multiregional, cohort-survival models."  Some applications of the model are made to data for China.
