Abstract
Although extensively theorized, determining the mechanisms that produce ethnic or racial segregation in schools and neighborhoods has proven difficult. We investigate one potential mechanism behind ethnic segregation; native flight from schools. In contexts where school enrollment is determined primarily by geographic proximity to schools, Native or White parents with a preference for schools with low minority concentrations may choose to move away from schools with higher minority concentrations among students, contributing to both residential and school segregation. Using detailed, population-wide, geo-coded register data on families and school catchment areas for elementary schools in Oslo, Norway, we investigate whether native parents move away from schools with higher shares of students with non-Western immigrant backgrounds. We first show that native origin families systematically move away from schools with high shares of students with non-Western immigrant backgrounds. Employing a Geographic Regression Discontinuity design, exploiting the fact that catchment area borders sort neighboring children into different schools, our results indicate that such moves may be causally linked to local school characteristics, not just their neighborhoods. This may contribute to segregation in schools and neighborhoods. However, the results are ambiguous and sensitive to model specifications, and more research is needed to draw firm conclusions.
