Community behavior arises from the decisions of each individual in the population. While physics provides tools to model large-scale behavior, incorporating individual preferences and decision-making remains an open problem. We used data-driven analysis to adapt hydrodynamic approaches to capture social behavior and examined a case study of residential dynamics in US Census data. Our model predicted an emergent societal memory at the transition between integration and segregation which slows community change.
