The Four Economic Sectors
Captions available
The idea
Economies are analyzed by sector: primary extracts raw materials, secondary manufactures finished goods, tertiary provides services, and quaternary produces ideas and information.
In practice
A miner works the primary sector, a factory worker the secondary, a nurse the tertiary, and a researcher the quaternary.
Where people slip
A developed economy is not free of the earlier sectors; it shifts what share of its workforce each sector employs.
