Society is reduced to three groups: The Upper Party, The Lower Party, and The Proles (who make up 85% of society). The Upper Party are effectively the ones in power, The Lower Party do a large amount of work for The Party as a whole, although they are unaware of a lot of things, and the proles are kept occupied by a constant supply of meaningless entertainment, preventing them from becoming politically-minded and overthrowing The Party. Everyone in society is kept under surveillance, and any observed behaviour that seems to imply that an individual has thoughts against The Party's interests results in the individual being arrested by The Thought Police.
