- Social system is a central term in sociological systems theory. The term draws a line to ecosystem, biological organisms, psychical systems and technical systems. They all form the environment of social systems. Minimum requirements for a social system is interaction of at least two personal systems or two persons acting in their roles. The first who formulated a systematic theory of social systems was Talcott Parsons where it was a part of his AGIL paradigm yet the social system is only a segment (or a "subsystem") of what Parsons calls action theory;  however, Vilfredo Pareto had used the term "social system" earlier but only as a sketch and not as an overall analytical scheme in the sense of Parsons. Jay Wright Forrester describes three counterintuitive behaviours as important: causes from symptoms are often far removed in time and space, identifying leverage points, conflicting short and long-term consequences.

- Social systems or social structure in general refer to entities or groups in definite relation to each other, to relatively enduring patterns of behavior and relationship within social systems, or to social institutions and norms becoming embedded into social systems in such a way that they shape the behavior of actors within those social systems. Social systems can be said to be the patterns of behavior of a group of people possessing similar characteristics due to their existence in same society.
