International Migration

Abstract

We are now at the final stage in the design of a basic microsimulation model – the integration of an elementary international migration module. This module will complete the model we have been developing gradually over the first five chapters. Just as with births, immigrants come into the simulation in the course of the projection, at a simulation time greater than zero. And like those entering the simulation through birth, immigrants are liable to experience all the demographic events in the model (fertility, mortality, mobility etc.). But unlike births, the creation of an immigrant actor is not the result of an event taking place in the simulation of an existing actor. Immigrant actors are Modgen cases of their own.
