An intentional community is a planne residential community designed to have a much higher degree of teamwork than other communities. The members of an intentional community typically hold a common social, political or spiritual vision and are often part of the alternative society. They also share responsibilities and resources. Intentional communities include cohousing, residential land trusts, ecovillages, communes, kibbutzim, ashrams, moshavs, and housing cooperatives. Typically, new members of an intentional community are selected by the community's existing membership, rather than by real-estate agents or land owners (if the land is not owned by the community). Though intentional communities do not claim to be utopias in the sense of perfect places, many do attempt to live a different and better sort of society, and as such many draw on historical utopian experiments or ideas in utopian fiction.
