There are a number of ways of defining communities and together they make up the interconnected systems of society. Some approaches include: geographic communities, such as suburbs or towns that are often referred to as "the local communities", communities of interest, identity, or circumstance, such as the business and its various industry sectors and the research communities, the non-profit and voluntary sectors, which are also known as the community sector; ethnic and cultural communities, communities of interest such as those for hobbies, sports or politics, communities of circumstance, such as youth, parenthood, senior citizens or the disabled.

Community is a term that has many different definitions. In a recent issue of Contemporary Sociology, Amitai Etzioni a sociologist who has written much on community defines it as: "a combination of two elements: A) A web of affect-laden relationships among a group of individuals, relationships that often crisscross and reinforce one another (rather than merely one-on-one or chainlike individual relationships). B) A measure of commitment to a set of shared values, norms and meanings, and a shared history and identity - in short to a particular culture".
