Under communism, there is no such thing as private property. All property is communally owned, and each person receives a portion based on what they need. A strong central government—the state—controls all aspects of economic production, and provides citizens with their basic necessities, including food, housing, medical care and education.
By contrast, under socialism, individuals can still own property. But industrial production, or the chief means of generating wealth, is communally owned and managed by a democratically elected government.
Another key difference between socialism and communism is the means of achieving them. In communism, a violent revolution in which the workers rise up against the middle and upper classes is seen as an inevitable part of achieving a pure communist state. Socialism is a less rigid, more flexible ideology. Its adherents seek change and reform, but insist on making these changes through democratic processes within the existing social and political structure, not overthrowing that structure.
A co-operative society is an autonomous association of persons united voluntarily to meet their common economic, social and cultural needs and aspirations through a jointly-owned and democratically-controlled enterprise
