While the model is excellent in the sense that it uses of simple logic to illustrate how segregation could emerge, through the mild tastes and preferences to locate amongst like social or economic groups. The model has no population turnover (Fossett and Waren, 2005), households are ‘immortal’ and thus a satisfied household can reside in the same location for ever.

The model is programmed in RepastJ and can be downloaded from here (30kb). More information about the model can be found on Hugh Stimson's blog.
