Critical mass (sociodynamics)

Critical mass in the context of sociodynamics refers to the minimum size or level of participation needed for a social phenomenon, movement, or behavior to become self-sustaining and significantly influence broader society. This concept is often applied to social movements, trends, or behaviors where a certain threshold of engagement or involvement is required before the movement can grow and spread effectively. The idea is drawn from physics, where critical mass describes the minimum amount of fissile material needed to maintain a nuclear chain reaction.
