This paper explores the social context of subjective well-being, happiness, and health using data from the World Values Survey, the US Benchmark Survey, and a comparable Canadian survey. The authors find that social capital, measured by family, neighborhood, religious, and community ties, strongly supports both physical health and subjective well-being. Social capital is linked to well-being through various channels, including marriage, family ties, workplace connections, civic engagement, trustworthiness, and trust. The study highlights the robust relationship between these social factors and happiness and life satisfaction, both directly and indirectly through their impact on health. The results suggest that social connections and trust are crucial for enhancing well-being, with the effects of social capital being particularly significant in improving physical health and subjective well-being. The paper also discusses methodological challenges and provides evidence from different national and international surveys to support these findings.This paper explores the social context of subjective well-being, happiness, and health using data from the World Values Survey, the US Benchmark Survey, and a comparable Canadian survey.
