Objective This article seeks to test group threat theory by interacting it with two other literatures: the campaign contribution literature and the racial order literature. Method It tests this interaction by measuring the effect of neighborhood racial composition on campaign contributions, controlling for mean adjusted gross income. Results It finds that white population is negatively correlated with campaign contributions, drowning out any income effect, and using a measure of “diversity” that includes black population reverses the direction of the relationship. Thus, increasing white homogeneity appears to increase majority complacence, while increasing racial diversity leads to campaign contributions as a threat response. Contributions. (1) This study offers indirect support to group threat theory and (2) it demonstrates that campaign contributions can be a threat response.
