"Putnam's work shows how social bonds are the most powerful predictor of life satisfaction. For example, he reports that getting married is the equivalent of quadrupling your income and attending a club meeting regularly is the equivalent of doubling your income. The loss of social capital is felt in critical ways: Communities with less social capital have lower educational performance and more teen pregnancy, child suicide, low birth weight, and prenatal mortality. Social capital is also a strong predictor of crime rates and other measures of neighborhood quality of life, as it is of our health: In quantitative terms, if you both smoke and belong to no groups, it's a close call as to which is the riskier behavior."--Jacket.
