Wikipedia: "An intentional community is a planned residential community designed from the start to have a high degree of social cohesion and teamwork. The members of an intentional community typically hold a common social, political, religious, or spiritual vision and often follow an alternative lifestyle. They typically share responsibilities and resources. Intentional communities include collective households, co-housing communities, eco-villages, communes, survivalist retreats, kibbutzim, ashrams, and housing cooperatives. New members of an intentional community are generally selected by the community's existing membership, rather than by real-estate agents or land owners (if the land is not owned collectively by the community)."
