Sector history

Since the early 1960s, the three-model economic sectors have been criticized as too limited. Therefore, in 1961, Jean Gottmann proposed for the first time the division of the tertiary sector by subdividing it into tertiary and quaternary sectors. In 1961, Gottmann described the “quaternary occupations” as those providing services that require research, such as ”analysis, judgment, briefly, brain and responsibility” and “what might be called the quaternary forms of economic activity; managerial and artistic functions, government, education, research and brokerage of all kinds of goods, services and securities” (Gottmann, 1961). In 1969, Deane suggested adding a new sector of the economy, the Quinary sector (Kellerman, 1985). As a result, the late 1960s brought together a new discussion in the field: the “Q-Sectors” of the economy.
