Abstract

This paper describes an agent-based model of socio-spatial segregation, result of a synthesis between « Schelling’s spatial segregation model » and a demographc model of dependency between household fertility rates and socio-economical status of their descendants. The resulting model shows a way in which a spatial segregation pattern can emerge from an initially – spatially as well as socially – homogenous population of households. Further on, the model shows a form of retroaction of spatial segregation on social polarity, which proceeds from a spatially inhomogeneous mechanism of revenue-taxes.

Agent-based model

An agent-based model (ABM) is a computational model for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) in order to understand the behavior of a system and what governs its outcomes. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming. Monte Carlo methods are used to understand the stochasticity of these models.

Model (person)

A model is a person with a role either to promote, display or advertise commercial products (notably fashion clothing in fashion shows) or to serve as a visual aid for people who are creating works of art or to pose for photography. Though models are predominantly female, there are also male models, especially to model clothing. Models may work professionally or casually. Modelling ("modeling" in American English) is considered to be different from other types of public performance, such as acting or dancing.

Sub-replacement fertility

Sub-replacement fertility is a total fertility rate (TFR) that (if sustained) leads to each new generation being less populous than the older, previous one in a given area. The United Nations Population Division defines sub-replacement fertility as any rate below approximately 2.1 children born per woman of childbearing age, but the threshold can be as high as 3.4 in some developing countries because of higher mortality rates. Taken globally, the total fertility rate at replacement was 2.33 children per woman in 2003.
