Service industries are those not directly concerned with the production of physical goods (such as agriculture and manufacturing). Some service industries, including transportation, wholesale trade and retail trade are part of the supply chain delivering goods produced in the agricultural and manufacturing sectors to final consumers.
Other services are provided directly to consumers. These include health care, education, information services, legal services, financial services, and public administration.
The service sector accounts for around 70-80 per cent of employment in modern economies.[1][2]
