White collar workers

The middle class is a class of people in the middle of a social hierarchy. In Weberian socio-economic terms, the middle class is the broad group of people in contemporary society who fall socio-economically between the working class and upper class. The common measures of what constitutes middle class vary significantly among cultures. One of the narrowest definitions limits it to those in the middle fifth of the nation's income ladder. A wider characterization includes everyone but the poorest 20% and the wealthiest 20%.

The term "middle class" is first attested in James Bradshaw's 1745 pamphlet Scheme to prevent running Irish Wools to France. Another phrase used in Early modern Europe was "the middling sort".

The term "middle class" has had several, sometimes contradictory, meanings. It was once defined by exception as an intermediate social class between the nobility and the peasantry of Europe. While the nobility owned the countryside, and the peasantry worked the countryside, a new bourgeoisie (literally "town-dwellers") arose around mercantile functions in the city. In France, the middle classes helped drive the French Revolution. Another definition equated the middle class to the original meaning of capitalist: someone with so much capital that they could rival nobles. In fact, to be a capital-owning millionaire was the essential criterion of the middle class in the industrial revolution.

The modern usage of the term "middle-class", however, dates to the 1913 UK Registrar-General's report, in which the statistician T.H.C. Stevenson identified the middle class as that falling between the upper-class and the working-class. Included as belonging to the middle-class are: professionals, managers, and senior civil servants. The chief defining characteristic of membership in the middle-class is possession of significant human capital.
