Social groups are formed when people come together for a common social purpose and develop social norms. There are several types of social groups including primary groups based on close personal ties like family, and secondary groups based on more impersonal ties like work or hobby interests. Social institutions are larger social structures like families, schools, governments and religions that have a recognized status and function within a society.
