The term community has two distinct meanings: 1) A group of interacting people, living in some proximity (i.e., in space, time, or relationship). Community usually refers to a social unit larger than a household that shares common values and has social cohesion. The term can also refer to the national community or international community, and, 2) in biology, a community is a group of interacting living organisms sharing a populated environment. A community is a group or society, helping each other.

In human communities, intent, belief, resources, preferences, needs, risks, and a number of other conditions may be present and common, affecting the identity of the participants and their degree of cohesiveness.

Since the advent of the Internet, the concept of community has less geographical limitation, as people can now gather virtually in an online community and share common interests regardless of physical location. Prior to the internet, virtual communities (like social or academic organizations) were far more limited by the constraints of available communication and transportation technologies.
