What determines school segregation? The crucial role of neighborhood factors
通过比较相邻人口普查区学生构成差异，发现邻里因素解释了约62%的种族隔离和44%的经济隔离，在城市地区作用更显著，表明应对教育机会不平等需要城市规划者参与。
We develop a novel strategy to identify the relative importance of school and neighborhood factors in determining school segregation. Using detailed student enrollment and residential location data, our research design compares differences in student composition between adjacent Census blocks served by different schools to analogous differences between those schools. Our findings indicate that neighborhood factors explain around 62% of racial segregation and 44% of economic segregation across all schools, playing an even more pronounced role in urban areas, where school segregation has been especially acute. These findings suggest that the involvement of urban planners is essential when attempting to confront inequality of opportunity through education.
