Human beings have an innate need to connect. A robust body of psychological and sociological research shows that being part of social groups — family, friends, community, work, or civic life — profoundly shapes identity, meaning, and well‐being. Feeling that one “belongs” contributes to a stable self‐concept and purpose, while active participation (through voting, volunteering, etc.) and rich social networks provide empowerment, resources, and support. Below we examine four core dimensions of these benefits, each supported by empirical studies and statistics.
1. Sense of Belonging
A sense of belonging is the feeling of being an integral part of one’s social groups and environments. Psychology researchers describe belonging as a deep connection to people and places, and alignment with one’s cultural or group identity . In other words, when people feel they “fit in” with friends, family, workplace or community, it reinforces who they are. This connectedness satisfies a basic human need (sometimes called the “need to belong”), which is even reflected in our biology . Belonging provides identity and purpose: it tells us “who I am and how I fit in the world.”
Empirical evidence links a healthy sense of belonging to positive life outcomes. Studies find that people with a strong sense of belonging enjoy better relationships, higher achievement, and improved health. For example, one review notes that belonging correlates with more positive social relationships, academic and career success, and better mental and physical health . Belonging buffers stress and stabilizes emotions: having a supportive group means one is less likely to feel isolated or adrift. Conversely, lacking belonging is harmful. Chronic social isolation has been shown to increase risks of depression, anxiety, poor sleep, and even early mortality. In fact, a meta‐analysis found that the health risks of isolation are roughly equivalent to smoking 15 cigarettes a day . These findings underscore that feeling socially integrated is tightly linked to emotional stability and a sense of meaning in life.
2. Civic Engagement
Civic engagement refers to active participation in community or public life — for example, voting, volunteering, community organizing, or activism. These activities give individuals a voice and purpose in society. Participating in civic life empowers people by enhancing their agency and self-efficacy. Involving oneself in a cause or local project often sparks reflection on personal values and roles: one model argues that civic engagement drives self‐exploration and identity formation, helping people answer “who am I and how do I contribute?” . In effect, civic acts can give one’s life meaning. For example, a study of socially excluded young adults found that community involvement and civic action not only brought connectedness and belonging, but also led to new self‐understanding and a stronger sense of meaning and identity .
There are many concrete benefits of civic participation. Research on youth, for instance, shows that adolescents who vote or volunteer tend to do better later in life: all forms of early civic engagement were linked to higher educational attainment and income, and specifically volunteering and voting predicted better mental health and lower substance use in adulthood . In practice, joining community service or advocacy can plug people into supportive networks (for jobs, mentorship, etc.) and reinforce positive self-image. Participants often report feeling empowered and satisfied knowing they’ve contributed to society. One summary notes that “voting and volunteering can be empowering and make people feel satisfaction in contributing to their communities” .
On the community side, civic engagement helps build social capital and trust. Economists and policymakers observe that neighborhoods with active volunteers, local organizations, and citizen involvement tend to be healthier and safer . In other words, when people invest time in local governance or service, it not only benefits others but also circulates back to themselves in the form of stronger community ties and a sense of shared purpose. For example, governments increasingly support civic involvement because it “establishes healthy and well‐developed neighborhoods” . Overall, engaging in civic life gives individuals a sense of agency, fosters pride in belonging to a community, and brings psychological rewards alongside societal improvements.
3. Social Networks
Social networks – comprising friends, family, coworkers, neighbors and acquaintances – provide both emotional support and practical resources. Psychologically, close friendships and family ties are potent buffers against stress and loneliness. High‐quality friendships in particular have been shown to predict well-being and protect against mental health issues . More broadly, social connection is “one of the strongest predictors of survival” and is “linked to higher well-being, safety, resilience and prosperity” . In other words, people embedded in robust networks tend to live longer and feel healthier. The diversity of one’s relationships also matters: having interactions across different social settings (work, neighborhood, family) is critical for overall health .
Practically speaking, networks open doors. A well‐known estimate is that up to 80% of jobs are filled through networking . Personal connections can provide leads, references, and insider information that one cannot easily get otherwise. Even beyond careers, neighbors and community groups can offer help in times of need (childcare, advice, loans, etc.). In fact, studies of neighborhoods show that strong local ties give people “vital sources of wellbeing and community capacity to help people get by and get ahead in life,” especially during stressful events . In sum, maintaining a broad social network brings practical benefits like information and opportunities and psychological benefits like companionship and a safety net. Research consistently finds that people with larger, supportive networks report lower stress and greater happiness.
4. Mental Health
Social inclusion has a profound impact on mental health. Ample evidence shows that being connected to others protects well-being, whereas social isolation and loneliness dramatically increase psychological risks. For example, systematic reviews find that loneliness more than doubles the odds of developing depression or anxiety . People who chronically feel alone are far more likely to suffer from mood disorders over time. Public‐health experts have called the current levels of social disconnection an “epidemic of loneliness,” noting that each step toward stronger social connection cuts the risk of many health problems and boosts life satisfaction . In practical terms, the U.S. Surgeon General reports that even modest increases in social connection correlate with better mental health, higher happiness, and improved performance at work and school .
The flip side is alarming: social isolation is a major predictor of mental illness and even suicide. One authoritative review quotes, “Social isolation is arguably the strongest and most reliable predictor of suicidal ideation, attempts, and lethal suicidal behavior” . In other words, people cut off from family, friends or community are at much higher risk of feeling hopeless. Similarly, a lack of emotional support magnifies vulnerability: adults and young people without close ties are significantly more likely to experience depression, anxiety, cognitive decline, or other disorders over time . Conversely, having confidants, family support, or community ties improves resilience and recovery from stress.
In summary, strong social bonds and inclusion are foundational to mental well-being. They offer meaning, reduce loneliness, and provide emotional cushioning. By contrast, social exclusion can precipitate loneliness and psychological distress. Countless studies agree that the best antidote to anxiety and depression is connectedness – from daily family dinners to community festivals to active friendships. In short, being part of society isn’t just socially desirable; it is crucial for emotional stability and overall health .
