School and neighborhood segregation are intertwined in complex ways. Schools reflect segregated neighborhoods, and school considerations reinforce neighborhood segregation. Over the past 25 years, racial segregation in neighborhoods and schools has slightly declined in terms of sorting, though children remain racially isolated in their neighborhoods and schools. Income segregation between schools, school districts, and neighborhoods has increased among children. Recent educational policy and demographic changes may break the link between neighborhood and school segregation. As population diversity increases, the proliferation of school choice leads schools and neighborhoods to resemble one another less, with schools becoming more segregated than their local neighborhoods. Regardless of the complicated and changing ways neighborhood and school segregation shape and reshape one another, segregation in both contexts remains high in the twenty-first century. Drawing on administrative data, I provide a quantitative portrait of the schools and neighborhoods of children from different racial/ethnic groups in 2015, documenting stark inequalities in these contexts. I conclude with a discussion of why segregation matters, what can be done about it, and why something must be done.

机会不均：美国的学校和社区隔离

学校和社区隔离以复杂的方式交织在一起。学校反映了隔离的社区，而学校的考虑加强了社区的隔离。在过去的25年中，社区和学校的种族隔离在分类方面略有下降，尽管儿童在社区和学校仍处于种族隔离状态。儿童之间的学校，学区和社区之间的收入隔离有所增加。最近的教育政策和人口变化可能会打破社区与学校隔离之间的联系。随着人口多样性的增加，学校选择的激增导致学校和社区之间的相似度降低，而学校变得比当地社区更加隔离。尽管社区和学校隔离的形成方式相互复杂并不断变化，但在二十一世纪，两种情况下的隔离仍然很高。利用行政数据，我对2015年来自不同种族/族裔群体的儿童的学校和社区进行了定量描述，记录了在这些情况下的严重不平等现象。最后，我讨论了隔离为何重要，可以采取什么措施以及为何必须采取某些措施。
