Communities are basic vital social units that provide the contexts in which people learn to live together to their mutual benefit. They are crucial to providing a richer and more fulfilling framework than we currently have for understanding and improving the quality of life for individuals and groups alike. The author defines what exactly prosocial communities are, identifying its elements and relevant interrelationships, and providing the available evidence in support of those conclusions. This work shows why a prosocial community is essential to the accomplishment of the goals of community psychology and its related fields, as well as how to create such communities.
