The effects of inequality, fragmentation, and social capital on collective action in a homogeneous society: Analyzing responses to the 2005 Japan Census

Using the initial response data to the 2005 Japan Census, I tried to ascertain the main determinants of the rate of uncollection. The major findings are as follows: (1) The decay of social capital lowers the response rate. (2) Inequality is associated with a low response rate, while generational heterogeneity is associated with a high response rate. This finding differs from the findings of previous studies. In sum, the effects of heterogeneities on collective action depend upon the features of society.
