Significance Residential racial segregation is associated with variation in habitat disturbance across cities in the United States. We repurposed open genetic data from 39 amphibian, bird, mammal, and reptile species sampled at 268 locations in cities across the United States and show that genetic diversity and connectivity are reduced in wildlife populations inhabiting minority neighborhoods. This suggests that these animal populations have slightly lower chances of persisting long term, limiting access to biodiversity in minority communities. Consistent, small effects across species indicate that the consequences of segregation on wildlife may be mitigated by more equitable urban development. By recognizing the ways human social factors negatively affect people and wildlife, we can change our behavior for the benefit of society.
