In sociology, post-industrial society is the state of development of a society in which the service sector generates more wealth than the industrial sector of the economy.

"Post-industrial society"[1]​ is a concept introduced by several theorists of sociology and economics—among them the Americans Daniel Bell, John Kenneth Galbraith and the Frenchman Alain Touraine—to describe the state reached by some developed societies in their social and economic system that would have evolved according to specific changes in their structure and that correspond to a state of development subsequent to the classic industrialization process of the Industrial Revolution. In the post-industrial society, an economic transition would have occurred, which would restructure the entire society, moving from an industrial economy to a service economy, based specifically on technical development and scientific research, education and information and communication technologies that would have transformed the previous forms of social reproduction and domination between social classes typical of industrialization.[2]​.
