Sociocultural system  A sociocultural system is a "human population viewed (1) in its ecological context and (2) as one of the many subsystems of a larger ecological system". In 1979, Marvin Harris outlined a universal structure of sociocultural systems. He mentioned infrastructure (production and population), structure (which is behavioural, like corporations, political organizations, hierarchies, castes), and a superstructure (which is mental, like beliefs, values, norms).
