Secondary group structure is in sociocultural materialism, structural groups in which members tend to interact without any emotional commitment to one another. These organizations are coordinated through bureaucracies. They perform many functions such as regulating production, reproduction, socialization, education, and enforcing social discipline. Examples include governments, parties, military, corporations, educational institutions, media, service and welfare organizations, and professional and labour organizations. Secondary and primary group structure is the basic dichotomy of social structure used in sociocultural materialism; together they encompass all human organisations.
