A community is a group of people connected through shared place, identity, interests, relationships, institutions, activities or a sense of belonging. In sociology, community can refer to a geographically located population such as a village or neighbourhood, but it can also describe groups whose members are connected despite living far apart. Religious communities, professional communities, online communities and communities of shared identity illustrate this broader meaning.
A community is therefore not simply a collection of people occupying the same physical space. It involves some form of social relationship, shared connection or recognised membership. The strength of that connection can vary considerably. Some communities involve frequent face to face interaction and extensive mutual support, while others consist mainly of symbolic identification or occasional communication.
Place is one of the oldest foundations of community. A village, neighbourhood or town can function as a community when residents share institutions, public spaces, services, social networks and a sense of local belonging. Geographic proximity creates opportunities for repeated interaction and can support relationships between households. However, physical proximity does not automatically create a strong community. A large residential development can contain thousands of people who have little interaction, while an online community can connect people who have never met physically. Modern communication technologies have therefore expanded the concept beyond traditional geographical boundaries. Community is increasingly understood as involving social relationships and shared meaning rather than location alone.
Shared identity can also create community. People may form communities around ethnicity, religion, disability, language, occupation, age, hobbies, political interests or cultural practices. These communities can provide belonging and social support, particularly for people who are geographically dispersed or who feel marginalised within wider society. Membership can be formal, as in a registered organisation, or informal, as in a network of people who recognise a common identity. Community boundaries can also be fluid. A person may simultaneously belong to a local neighbourhood, professional community, family community, religious community and online community. These overlapping memberships demonstrate that community is a multidimensional social concept rather than a single fixed type of group.
Communities commonly develop institutions and organisations that help coordinate collective activity. Schools, religious organisations, sports clubs, charities, residents associations, libraries, community centres and voluntary groups can all provide settings for interaction and cooperation. Informal networks can perform similar functions by helping people exchange information, childcare, practical assistance, emotional support or local knowledge. Community institutions can strengthen social capital, meaning resources available through social relationships, trust and networks. However, not every community has equal resources or strong internal cohesion. Poverty, discrimination, population turnover, conflict and weak infrastructure can affect a community's capacity to organise and support its members. Community therefore describes a social structure, not an automatic guarantee of solidarity or wellbeing.
A sense of belonging is an important dimension of community. People may regard a community as part of their identity and develop emotional attachments to its people, places, history or traditions. Shared memories, festivals, landmarks, stories and collective experiences can strengthen this sense of belonging. At the same time, communities can have boundaries that distinguish members from non members. Such boundaries can provide solidarity but can also produce exclusion when membership is defined rigidly.
Sociological analysis therefore considers both inclusion and exclusion. A strong community may provide support and identity for insiders while making participation difficult for outsiders. Community should consequently be understood as a relationship involving belonging, boundaries, interaction and shared meanings rather than simply as an inherently positive social arrangement.
Communities change over time as populations migrate, institutions develop, technology changes and economic conditions shift. Industrialisation and urbanisation transformed traditional forms of local community, while digital communication created new forms of geographically dispersed community. Migration can produce new cultural communities while also transforming existing local communities. Population ageing, housing development, economic restructuring and transport changes can alter local social networks. Community organisations can disappear or emerge in response to these changes. Historical communities may therefore retain symbolic importance even when their original economic or social structures have changed. The study of community examines these processes of continuity, transformation, fragmentation and reconstruction.
Community is closely related to concepts such as society, social group, network and neighbourhood but should not be treated as synonymous with them. Society usually refers to a much broader system of social relationships and institutions, while a social group can be any collection of people who interact or share characteristics. A network emphasises connections among individuals or organisations, whereas community usually implies some additional sense of shared belonging, identity, place or purpose.
A neighbourhood is commonly a geographical community, but not every community is a neighbourhood. These distinctions help explain why people can belong to communities that are not physically located near one another and why people living in the same area may not necessarily form a cohesive community.
Communities are significant because they connect individuals to wider social structures through relationships, institutions and shared meanings. They can provide social support, information, identity, opportunities for participation and mechanisms for collective action. They can also reproduce inequalities if some residents or groups have greater resources, influence or recognition than others. Studying communities therefore involves examining who belongs, who participates, which institutions exist, how resources are distributed, how relationships operate and how boundaries are maintained. Community is neither simply a geographical location nor an automatically harmonious group. It is a social form produced through interaction, shared experience, institutions and belonging. Its strength and character depend on historical, economic, cultural, demographic and technological conditions.
