Social institutions are established sets of norms and subsystems that support a society's survival. Examples include families, governments, and universities. A social institution performs social functions like satisfying needs, socializing individuals, and coordinating and stabilizing a culture. The family is the most important social institution. It socializes children, transmits culture, and provides affection, security, and social status. Education is also a major social institution. It transmits knowledge, values, and behaviors between generations through both formal schooling and informal family education. Schools socialize children and prepare them for occupational and social roles to support society.
