White NIMBYism and diversity close to home.

Objective: We use a survey experiment to study what explains white "not in my backyard" opposition (NIMBYism) to dense and affordable housing—racial threat, material self‐interest, or both. Methods: In a survey experiment on white U.S. respondents, we vary the presence of a racial prime about black and Latinx community organizations and the proximity of the housing development to the subject's home. We then measure levels of support for a proposed hypothetical housing development, willingness to take political action in support of or opposition to the development, and support for a number of housing‐related and redistributive policies. Results: We find that a racial threat, a material self‐interest threat, and a combined racial and material self‐interest threat decrease support for a proposed housing development. These effects are moderated by racial resentment, ideology, and partisanship such that the effects of the treatments are primarily driven by Republicans, conservatives, and the highly racially resentful. These groups are more threatened than others by either Latinx and black people moving in, the development being in their own neighborhood, or both. Conclusion: These findings indicate that racial and material perceived threats play important and interlocking roles in white Americans' resistance to multifamily housing being built. In a context where local political institutions empower an unrepresentative group of disproportionately white, economically privileged neighbors to mount opposition to dense housing, it is important to understand how white opposition to new dense housing is shaped by racial and financial concerns.
