How does income relate to social capital across individuals?
Core argument: Classifying 129 activities as inherently social across five categories, the authors find social capital rises with post-tax, post-transfer (full) income but at a diminishing rate.
We classify 129 activities as inherently social and group them into five major categories—caring for and helping household members, caring for and helping non-household members, socializing/relaxing/leisure, religious and spiritual activities, and volunteering. Social capital rises with post tax, post transfer (full) income but at a diminishing rate. The association between social capital and income is strongest for black individuals and weakest for Hispanic individuals. Individuals who receive a greater share of their income from government sources tend to have lower levels of social capital, even conditional on demographics. Racial and ethnic minorities in the United States have weaker social capital, although for different reasons. On average, non-Hispanic black individuals have relatively weaker family strength, but relatively stronger social connection. Hispanic individuals have relatively strong family strength and work scores but have lower scores for other components of social capital.
