Skip to 0 minutes and 11 secondsHere we have a NetLogo model of Thomas Schelling's segregation model. NetLogo is freely downloadable, and I strongly recommend downloading NetLogo and playing for yourself with the same models. The segregation model is based on the population living in a square grid, and it is composed of green and red agents. Now, each of the agents has a preference of living in a neighbourhood with a slight majority of their own kind. Here, we put it at 60%, so the green ones over here are not satisfied because they're living in an environment dominated by red ones. They'd prefer to move to a region where there are more greens. Let's see what happens when this model starts running.
Skip to 1 minute and 15 secondsWe see that they are relocating and that they are clustering.
Skip to 1 minute and 24 secondsWhat emerges here is neighbourhoods that are really homophilous, or completely similar, concerning their colour, whereas if you are aware of the percentage, it's only a slight majority of their own kind that they prefer. This micro level preference results in a much more complete separation on a macro level. This is typically the emergence of separation due to individual behaviour.
Agent based model 2: Emergence of social segregation
This lecture goes through a simulation of Schelling’s model of segregation demonstrated in software called NetLogo.
After a small quiz, we will explore this model in the browser version of Netlogo.
