Abstract

In the M.P. Regionalized World Model, one of the most important submodels is the population model. In its present state there are especially two purposes for which the model serves:

(1) The model can be used to investigate different population policies. The model calculates an equilibrium fertility factor that would gradually lead to population equilibrium. The user of the model can specify the year when the equilibrium policy is to start, and the length of the transition interval after which the equilibrium fertility should be reached. Thus it is possible to investigate the effects of postponing the application of equilibrium policies; and

(2) A second feature of the model is that you may not only investigate a decreasing fertility, but also an increasing mortality due to lack of protein. This will be helpful for analyzing the population growth of South East Asia.
