A post-industrial society is a stage in a society's development during which the economy transitions from one that primarily provides goods to one that primarily provides services. In other words, the service sector (e.g. nurses, teachers, researchers, social workers, lawyers, etc) accounts for more of the economic growth and wealth than the manufacturing sector (e.g. construction workers, textile mills, food manufacturers, production workers, etc). The economic transformation associated with a post-industrial society subsequently transforms society as a whole.

Information, services, and advanced technology are more important in post-industrial societies than manufacturing tangible goods. As the name suggests, a post-industrial society follows an industrialized society, which focused on mass producing goods with the aide of machinery. 

A transition from the production of goods to the production of services, with very few firms directly manufacturing any goods.The replacement of blue-collar manual labourers with technical and professional workers—such as computer engineers, doctors, and bankers—as the direct production of goods is moved elsewhere.The replacement of practical knowledge with theoretical knowledge.Greater attention being paid to the theoretical and ethical implications of new technologies, which helps society avoid some of the negative features of introducing new technologies, such as environmental accidents and massive widespread power outages.The development of newer scientific disciplines—such as those that involve new forms of information technology, cybernetics, or artificial intelligence—to assess the theoretical and ethical implications of new technologies.A stronger emphasis on the university and polytechnic institutes, which produce graduates who create and guide the new technologies crucial to a postindustrial society.
