Community

A community is a social unit with a shared socially-significant characteristic, being place, set of norms, culture, religion, values, customs, or identity. Communities may share a sense of place situated in a given geographical area or in virtual space through communication platforms. Durable good relations that extend beyond immediate genealogical ties also define a sense of community, important to people's identity, practice, and roles in social institutions such as family, home, work, government, society, or humanity at large. Although communities are usually small relative to personal social ties, "community" may also refer to large-group affiliations such as national communities, international communities, and virtual communities.
In terms of sociological categories, a community can seem like a sub-set of a social collectivity.
In developmental views, a community can emerge out of a collectivity.
The English-language word "community" derives from the Old French comuneté, which comes from the Latin communitas "community", "public spirit".
Human communities may have intent, belief, resources, preferences, needs, and risks in common, affecting the identity of the participants and their degree of cohesiveness.

Perspectives of various disciplines

Archaeology

of social communities use the term "community" in two ways, mirroring usage in other areas. The first meaning is an informal definition of community as a place where people used to live. In this literal sense it is synonymous with the concept of an ancient settlement—whether a hamlet, village, town, or city. The second meaning resembles the usage of the term in other social sciences: a community is a group of people living near one another who interact socially. Social interaction on a small scale can be difficult to identify with archaeological data. Most reconstructions of social communities by archaeologists rely on the principle that social interaction in the past was conditioned by physical distance. Therefore, a small village settlement likely constituted a social community and spatial subdivisions of cities and other large settlements may have formed communities. Archaeologists typically use similarities in material culture—from house types to styles of pottery—to reconstruct communities in the past. This classification method relies on the assumption that people or households will share more similarities in the types and styles of their material goods with other members of a social community than they will with outsiders.

Ecology

In ecology, a community is an assemblage of populations—potentially of different species—interacting with one another. Community ecology is the branch of ecology that studies interactions between and among species. It considers how such interactions, along with interactions between species and the abiotic environment, affect social structure and species richness, diversity and patterns of abundance. Species interact in three ways: competition, predation and mutualism:

Competition typically results in a double negative—that is both species lose in the interaction.
Predation involves a win/lose situation, with one species winning.
Mutualism sees both species co-operating in some way, with both winning.

The two main types of ecological communities are major communities, which are self-sustaining and self-regulating, and minor communities, which rely on other communities and are the building blocks of major communities. Moreover, we can establish other non-taxonomic subdivisions of biocenosis, such as guilds.

Philosophy

In light of the debate about the meaning of the “European Community,” a series of European philosophers began to raise concerns with how community has been traditionally conceived in the West. They questioned whether the closed, exclusionary, and identitarian models of community found in the traditions of Communitarianism in Anglo-American philosophy and Classical Social Theory, were suitable for our globalized world. However, instead of abandoning the desire to belong in a community, they attempt to reconceptualize community in an open and inclusive manner. Jean-Luc Nancy is credited with starting this debate with his book The Inoperative Community, followed by Maurice Blanchot’s The Unavowable Community, Giorgio Agamben’s The Coming Community, and Roberto Esposito’s Communitas. Jean-Luc Nancy revised his theory of community in Being Singular Plural, and he delivered a series of reflections on the terms and motifs of this debate in The Disavowed Community. Other books related to this series include Zygmunt Bauman’s Community, Greg Bird’s Containing Community, Miranda Joseph’s Against the Romance of Community, and Alphonso Lingis’ The Community of Those Who Have Nothing in Common.

Semantics

The concept of "community" often has a positive semantic connotation, exploited rhetorically by populist politicians and by advertisers
to promote feelings and associations of mutual well-being, happiness and togetherness—veering towards an almost-achievable utopian community.
In contrast, the epidemiological term "community transmission" can have negative implications, and instead of a "criminal community" one often speaks of a "criminal underworld" or of the "criminal fraternity".

Sociology

Early sociological studies identified communities as fringe groups at the behest of local power elites. Such early academic studies include Who Governs? by Robert Dahl as well as the papers by Floyd Hunter on Atlanta. At the turn of the 21st century the concept of community was rediscovered by academics, politicians, and activists. Politicians hoping for a democratic election started to realign with community interests.

Others

The Shona include ancestral spirits in their conceptualisation of the community.

Key concepts

''Gemeinschaft and Gesellschaft''

In Gemeinschaft und Gesellschaft, German sociologist Ferdinand Tönnies described two types of human association: Gemeinschaft and Gesellschaft. Tönnies proposed the Gemeinschaft–Gesellschaft dichotomy as a way to think about social ties. No group is exclusively one or the other. Gemeinschaft stress personal social interactions, and the roles, values, and beliefs based on such interactions. Gesellschaft stress indirect interactions, impersonal roles, formal values, and beliefs based on such interactions.

Sense of community

In a seminal 1986 study, McMillan and Chavis identify four elements of "sense of community":

membership: feeling of belonging or of sharing a sense of personal relatedness,
influence: mattering, making a difference to a group and of the group mattering to its members
reinforcement: integration and fulfillment of needs,
shared emotional connection.

A "sense of community index" was developed by Chavis and colleagues, and revised and adapted by others. Although originally designed to assess sense of community in neighborhoods, the index has been adapted for use in schools, the workplace, and a variety of types of communities.
Studies conducted by the American Psychological Association indicate that young adults who feel a sense of belonging in a community, particularly small communities, develop fewer psychiatric and depressive disorders than those who do not have the feeling of love and belonging.

Socialization

The process of learning to adopt the behavior patterns of the community is called socialization. The most fertile time of socialization is usually the early stages of life, during which individuals develop the skills and knowledge and learn the roles necessary to function within their culture and social environment. For some psychologists, especially those in the psychodynamic tradition, the most important period of socialization is between the ages of one and ten. But socialization also includes adults moving into a significantly different environment where they must learn a new set of behaviors.
Socialization is influenced primarily by the family, through which children first learn community norms. Other important influences include schools, peer groups, people, mass media, the workplace, and government. The degree to which the norms of a particular society or community are adopted determines one's willingness to engage with others. The norms of tolerance, reciprocity, and trust are important "habits of the heart", as de Tocqueville put it, in an individual's involvement in community.

Development

Community development is often linked with community work or community planning, and may involve stakeholders, foundations, governments, or contracted entities including non-government organisations, universities or government agencies to progress the social well-being of local, regional and, sometimes, national communities. More grassroots efforts, called community building or community organizing, seek to empower individuals and groups of people by providing them with the skills they need to effect change in their own communities. These skills often assist in building political power through the formation of large social groups working for a common agenda. Community development practitioners understand how to work with individuals and affect communities' positions within the context of larger social institutions. Public administrators, in contrast, understand community development in the context of rural and urban development, housing and economic development, and community, organizational and business development.
Formal accredited programs conducted by universities, as part of degree granting institutions, are often used to build a knowledge base to drive curricula in public administration, sociology and community studies. The General Social Survey from the National Opinion Research Center at the University of Chicago and the Saguaro Seminar at the Harvard Kennedy School are examples of national community development in the United States. The Maxwell School of Citizenship and Public Affairs at Syracuse University in New York State offers core courses in community and economic development, and in areas ranging from non-profit development to US budgeting. In the United Kingdom, the University of Oxford has led in providing extensive research in the field through its Community Development Journal, used worldwide by sociologists and community development practitioners.
At the intersection between community development and community building are a number of programs and organizations with community development tools. One example of this is the program of the Asset Based Community Development Institute of Northwestern University. The institute makes available downloadable tools to assess community assets and make connections between non-profit groups and other organizations that can help in community building. The Institute focuses on helping communities develop by "mobilizing neighborhood assets" – building from the inside out rather than the outside in. In the disability field, community building was prevalent in the 1980s and 1990s with roots in John McKnight's approaches.
