Finding the appropriate size of political states or other decision-making units, determining their optimal relationship to social capital and to infrastructural capital, is a major focus of political science. In management science there are studies of the ideal size of corporations, and some in anthropology and sociology study the ideal size of villages. Dennis Fox, a retired professor of legal studies and psychology, proposed an ideal village size of approximately 150 people in his 1985 paper about the relationship of anarchism to the tragedy of the commons.
