Community

society Maturity 7-9 Vital Level 3 Next article →

A community is a social unit made of people who share significant characteristics. These shared traits might include a specific place, a set of norms, a culture, or a religion. People also form communities through shared values, customs, or identities. Some communities exist in physical locations like a village or a town. Others exist in virtual space through online communication platforms. Communities are vital because they help define a person's identity and social roles. They can range from small local groups to massive national or international affiliations.

Sociologists study how these groups function and interact. One important way to view human associations is through the work of Ferdinand Tönnies. In 1887, he described two distinct types of social ties. He called the first type Gemeinschaft, which is often translated as "community." This type focuses on personal interactions, shared values, and close-knit beliefs. The second type is Gesellschaft, or "society." This type focuses on impersonal roles and formal, indirect interactions. Most human groups exist somewhere on the spectrum between these two types.

In the field of ecology, the term community has a different meaning. An ecological community is an assemblage of different populations interacting with one another. Community ecology studies how these species interact with each other and their environment. These interactions can affect species richness and how many individuals live in an area. Species generally interact in three specific ways. Competition occurs when species struggle for resources, often resulting in a loss for both. Predation is a win-lose situation where one species wins. Mutualism is a cooperative interaction where both species benefit.

Ecologists also categorize these biological groups by their scale and function. Major communities are self-sustaining and self-regulating systems, such as a forest or a lake. Minor communities are smaller building blocks that rely on other communities to survive. An example is fungi decomposing a fallen log. Archaeologists use the word "community" to study the ancient past in two ways. They may use it to describe a physical settlement, like a hamlet or a city. They also use it to describe a group of people who lived near each other and interacted socially.

Because social interactions are hard to see in the archaeological record, researchers use material culture. They look for similarities in house types or styles of pottery. They assume that households in the same community share more similarities with each other than with outsiders. This helps them reconstruct how ancient people lived together. In human society, the process of learning community behaviors is called socialization. This is how individuals adopt the patterns and norms of their group. Families are the primary influence on socialization, especially for children. Schools, peer groups, and the media also play major roles in this process.

Psychologists have found that a "sense of community" is essential for well-being. In 1986, researchers McMillan and Chavis identified four key elements of this feeling. These elements are membership, influence, reinforcement, and a shared emotional connection. Membership means feeling a sense of personal relatedness to the group. Influence means members feel they matter to the group and it matters to them. Reinforcement involves the fulfillment of needs through the group. A shared emotional connection provides the bond between members.

This sense of belonging has measurable effects on mental health. The American Psychological Association has noted that young adults in small communities often experience fewer psychiatric or depressive disorders. This is linked to the feeling of love and belonging provided by the group. Beyond psychology, communities can be intentionally developed or organized. Community development involves planning to improve social well-being through various agencies. This can include local governments, universities, or non-government organizations. Grassroots efforts, known as community building, focus on empowering individuals to create change from within.
