Proles is a term used in George Orwell’s novel Nineteen Eighty-Four to refer to the working class of Oceania (i.e. the proletariat).
According to 1984, the society of Oceania was divided into 3 distinct classes: Inner Party, Outer Party, and proles (upper, middle, and lower classes, respectively). In the novel, 85% of the population of Oceania (which covers the Americas, Britain, Ireland, Australia, New Zealand, Papua New Guinea and southern Africa below the River Congo) are proles. They were given little education, worked at jobs in which tough physical labour was the norm, lived in poverty (but qualitatively richer than the Outer Party members with regard to certain freedoms inherent to their relative anonymity), had plenty of children, and usually died by the age of sixty.
