Schelling's Segregation Model Explained

Segregation happens, even when no one explicitly wants it. Imagine a simple

neighborhood shown as a grid of blue and red dots. In this model,

every individual follows just one simple rule. I want a few neighbors like

me. Even thirty three percent is enough. If that mild preference is not

met, the person decides to move. This repeats as others across the

grid also seek their preference. But as they move, a surprising pattern

begins to emerge. No one asked for segregation, but the system created it anyway.

Small preferences create large patterns in housing, schools, and teams.
