By examining how populations of interest groups are comprised, this work fills an important gap between existing theories of the origins of individual interest groups and studies of interest-group influence. The population ecology model of interest communities developed here builds on insights first developed in population biology and later employed by organizational ecologists.
After examining the demography of interest organizations in the fifty American states, the population ecology model is used to account for variations in the density and diversity of their interest communities, the nature of competition among similar interest organizations to establish viable niches, and the impact of alternative configurations of interest communities on the legislative process and the policies it produces. These empirical findings suggest that the environment of interest communities is highly constraining, limiting their size, composition, and potential impact on politics.
