Community: The Dynamics of Social Connection and Collective Identity
At its core, a community is a social unit comprising a group of people who share one or more socially significant characteristics. These bonds can be forged through a shared sense of place, a common set of norms, culture, religion, values, customs, or a collective identity. While we often think of communities in terms of physical proximity—such as a neighborhood or a village—they also exist in virtual spaces through digital communication platforms.
Beyond simple geography, a true sense of community is defined by durable social relations that extend beyond immediate family ties. These connections are vital to an individual's identity, their social practices, and their roles within larger institutions like government, work, and society. While many communities are small, the term also encompasses large-scale affiliations, including national and international communities.

Key Facts
- Etymology: The word derives from the Old French comuneté and the Latin communitas, meaning "community" or "public spirit."
- Scope: Communities range from small local groups to vast virtual networks and global international affiliations.
- Core Elements: A "sense of community" is typically built on membership, influence, reinforcement, and shared emotional connection.
- Sociological View: A community is often viewed as a subset of a social collectivity, or something that emerges from one.
The Psychology of Belonging: Sense of Community
What makes a group of people feel like a community? In a seminal 1986 study, researchers McMillan and Chavis identified four critical elements that create a "sense of community":
- Membership: A feeling of belonging or a sense of personal relatedness to others.
- Influence: The feeling that the individual matters to the group, and that the group matters to its members.
- Reinforcement: The integration of the individual and the fulfillment of their needs through the group.
- Shared Emotional Connection: A bond based on shared history or experiences.

Gemeinschaft and Gesellschaft
Sociology often distinguishes between two types of social ties: Gemeinschaft (community), referring to close-knit, traditional social bonds, and Gesellschaft (society), referring to the more impersonal, contractual relationships found in modern urban life.
Community Development and Organizing
Community building is the process of creating these social bonds, while community development focuses on the tools and programs used to improve the collective well-being of a group. One prominent approach is Asset Based Community Development (ABCD), championed by the ABCD Institute of Northwestern University. This method focuses on "mobilizing neighborhood assets," building a community from the inside out by leveraging existing strengths rather than focusing on external deficits.
Organizing these groups generally falls into three categories:
- Grassroots Organizing: Driven by the local people themselves.
- Coalition Building: Forming alliances between different groups for a common goal.
- Institution-Based Community Organizing: Also known as broad-based organizing, this often takes the form of faith-based or congregation-based initiatives.

Diverse Types of Communities
Communities manifest in various forms depending on the primary bond that holds them together. These can be based on shared interests, historical commemorations, or digital interaction.
| Community Type | Primary Characteristic | Example |
|---|---|---|
| Geographic | Shared physical location | Neighborhoods, towns, villages |
| Interest-Based | Shared hobbies or beliefs | Summer solstice gatherings at Stonehenge |
| Virtual | Digital communication platforms | Online forums, social media groups |
| Identity-Based | Shared culture or heritage | National or ethnic communities |

Virtual communities have become increasingly prevalent, allowing people to maintain long-distance relationships and find technical advice through "weak ties." However, these spaces also face challenges, such as the rise of cyberbullying and the growth of extremist groups on encrypted platforms.

Frequently Asked Questions
What is the difference between a community and a collectivity?
A collectivity is a broader category of people. A community is often a subset of a collectivity that has developed social intimacy, shared experience, and durable relations that are subjectively important to the members' identities.
What are the four elements of a "sense of community"?
According to McMillan and Chavis, the four elements are membership (belonging), influence (mattering), reinforcement (need fulfillment), and a shared emotional connection.
What is Asset Based Community Development (ABCD)?
ABCD is a development strategy that focuses on identifying and mobilizing the existing assets and strengths within a neighborhood to build the community from the inside out, rather than relying on outside intervention.
Can a community exist without a physical location?
Yes. Virtual communities exist in digital spaces, and communities of interest or identity can connect people across vast distances through shared values, beliefs, or goals.
What is the difference between grassroots and institution-based organizing?
Grassroots organizing starts from the bottom up with local residents, whereas institution-based organizing utilizes existing structures, such as churches or other organizations, to mobilize people.
