Types of socialism include a range of economic and social systems characterised by social ownership and democratic control of the means of production and organizational self-management of enterprises as well as the political theories and movements associated with socialism. Social ownership may refer to forms of public, collective or cooperative ownership, or to citizen ownership of equity in which surplus value goes to the working class and hence society as a whole. There are many varieties of socialism and no single definition encapsulates all of them, but social ownership is the common element shared by its various forms Socialists disagree about the degree to which social control or regulation of the economy is necessary, how far society should intervene, and whether government, particularly existing government, is the correct vehicle for change.

Communism is a left-wing to far-left sociopolitical, philosophical, and economic ideology within the socialist movement, whose goal is the creation of a communist society, a socioeconomic order centered around common ownership of the means of production, distribution, and exchange that allocates products to everyone in the society based on need. A communist society would entail the absence of private property and social classes, and ultimately money and the state.
