County-level measure of social capital
Here you will find data on the estimated stock of social capital in each US county for the years 1990, 1997, 2005, and 2009.
PLEASE NOTE: The data are presented "as is" without any implied guarantees for accuracy, and that there are slight differences between 1990/1997 and 2005 as a result of the switch from the SIC to the NAICS codes.
