Social Connection Index Calculator
Social connection is a fundamental human need with profound effects on physical and mental health. The U.S. Surgeon General's 2023 Advisory identified loneliness and isolation as a public health crisis, finding that lacking social connection carries health risks comparable to smoking up to 15 cigarettes per day. This calculator assesses your social connection across four dimensions: relationship quantity, relationship quality, sense of belonging, and community participation. Rate each question from 1 (Very poor/never) to 10 (Excellent/daily).
Self-assessment screening tool only. Not a clinical assessment.
Relationship Quantity (1 = Very low, 10 = Very high)
Relationship Quality
Sense of Belonging
Community Participation
Social connection index formula
Social Connection Index = (sum of all 8 ratings / 80) * 100
Each item is rated 1 to 10, giving a maximum raw score of 80. The score is normalized to a 0-100 scale. Equal weight is applied to all four dimensions (quantity, quality, belonging and community participation), reflecting the multi-dimensional nature of social health recognized in NIH research.
Understanding your connection index
- 70-100 (Strong): You have a healthy social network. Maintain and nurture these connections with consistent, quality time.
- 40-69 (Moderate): Some social connections exist but there is room to deepen quality or expand participation. Identify which dimension is lowest.
- Below 40 (Low): Social isolation risk is elevated. Consider proactive steps to build connection or speak with a professional about loneliness.
Social connection calculator: frequently asked questions
Why does social connection matter for health?
Research by the NIH and leading epidemiologists including Dr. Julianne Holt-Lunstad has found that social isolation is associated with a 29% increased risk of heart disease, a 32% increased risk of stroke and a 50% increased risk of dementia. The U.S. Surgeon General's 2023 Advisory on the Healing Effects of Social Connection and Community identified loneliness and isolation as a major public health concern.
What is the difference between social connection and social support?
Social connection refers to the sense of belonging and closeness to others. Social support is the practical help, emotional comfort and advice that relationships provide. Both matter for health. Research shows that perceived support quality is often more important than the raw quantity of social contacts.
How many close friends do people typically have?
Research by evolutionary psychologist Robin Dunbar suggests that humans maintain approximately 5 intimate relationships, 15 close friendships, and 50 good friends within their social network. The U.S. Survey Center on American Life (American Enterprise Institute) found the median American had 3 close friends in 2021, down from 10 in 1990.
How can I improve my social connection score?
Evidence-based strategies include scheduling regular contact with close relationships (not just passive social media), joining community groups or clubs, volunteering, participating in faith communities, and being proactive in initiating contact. The NIH-funded AARP Foundation Connect2Affect program and the U.S. Administration for Community Living provide resources for building social connection.
Is online social connection as beneficial as in-person connection?
Research is mixed. A 2022 NIH-funded meta-analysis found in-person interaction has stronger health benefits than online interaction, though technology can supplement (not replace) face-to-face relationships for people with limited access. The U.S. Surgeon General's Advisory recommends prioritizing in-person connection and using technology as a bridge, not a substitute.
