Schelling's Segregation Model

Schelling's segregation models demonstrate that local preferences and relocation interactions can produce substantial aggregate separation without agents explicitly requesting the final pattern. Results depend on the model's preferences, neighborhoods, vacancies, and movement rules.

Schelling's model illustrates how local relocation rules can generate aggregate separation without agents explicitly demanding the final pattern. Moving changes other agents' neighborhoods, which can trigger further moves. The causal chain is relational: a move affects both its destination and the place left behind.

This is a possibility demonstration, not a fixed conversion from one preference percentage to another or a complete explanation of real residential segregation. Outcomes depend on neighborhood definitions, vacancies, preferences, and update rules. Observed separation alone cannot identify motives, and a simulation does not remove the need to examine discriminatory institutions, unequal resources, or restricted choices.

When to use it

When collective outcomes are more extreme than individual preferences; when segregation (social, organizational, informational) exceeds what anyone individually desires; when understanding how mild preferences cascade into extreme patterns; when structural interventions would produce outcomes better aligned with actual preferences.

How it can help

Use the model to generate a candidate mechanism linking local moves to collective patterns. Test alternative rules and investigate real constraints and institutions before inferring causes or selecting interventions.
