The production of social capital in US counties

A growing belief exists that social capital contributes to economic growth of communities. In this paper, we identify inputs into the production of social capital at the level of US counties, using an array of individual and community factors that are theoretically important determinants of social capital. We use data from the Bureau of the Census, County Business Patterns, USA Counties on CD, National Center for Charitable Statistics, and the Regional Economic Information System for two time periods. Ethnic homogeneity, income inequality, attachment to place, education, age, and female labor force participation are strongly associated with levels of social capital across US counties.
