Most U.S. students attend racially segregated schools. To understand this pattern, I employ a survey experiment with New York City families actively choosing schools and investigate whether they express racialized school preferences. I find school racial composition heterogeneously affects white, black, Latinx, and Asian parents' and students' willingness to attend schools. Independent of characteristics potentially correlated with race, white and Asian families preferred white schools over black and Latinx schools, Latinx families preferred Latinx schools over black schools, and black families preferred black schools over white schools. Results, importantly, demonstrate that racial composition has larger effects on white and Latinx parents' preferences compared with white and Latinx students and smaller effects on black parents compared with black students. To ensure results were not an artifact of experimental conditions, I validate findings using administrative data on New York City families' actual school choices in 2013. Both analyses establish that families express heterogenous racialized school preferences.
