An important topic in the study of segregation are comparisons across space and time. This article extends current approaches in segregation measurement by presenting a five-term decomposition procedure that can be used to understand more clearly why segregation has changed or differs between two comparison points. Two of the five terms account…

Automatic admissions policies (AAPs, "percent plans") redistribute college-going opportunities across segregated high schools to diversify college enrollments, increasing opportunities at predominantly minority high schools. If students "game" AAPs by attending schools with increased opportunities, AAPs could alter racial…

Student mobility and school segregation are two important issues with significant equity implications for urban school districts that are often addressed separately. This article examines the relationship between student mobility and school segregation. The findings indicate that more segregated schools typically have smaller within-school…

The establishment of new school districts in predominantly White municipalities in the South is restructuring school and housing segregation in impacted countywide school systems. This article compares the contribution of school district boundaries to school and residential segregation in the Southern counties that experienced secession since…

A half century of research details how segregating racial groups in separate schools corresponds with disparities in funding and quality teachers and culturally narrow curricula. But we know little about whether young Latino children have entered less or more segregated elementary schools over the past generation. This article details the growing…

This paper provides the first population-based evidence on how much standardized test scores vary among public school districts within each state and how segregation explains that variation. Using roughly 300 million standardized test score records in math and ELA for grades 3 through 8 from every U.S. public school district during the 2008-09 to…

A new report by the American Enterprise Institute (AEI), "Differences by Design?," compares differences in approaches and demographics between and among charter school models and local "traditional public schools." Using three national data sets, the report effectively captures the national universe of charter schools. It…

In January 2010, the UCLA-based Civil Rights Project (CRP) released "Choice without Equity: Charter School Segregation and the Need for Civil Rights Standards." The study intended to report on, among other things, levels of racial segregation in charter schools across the United States. The authors use 2007-08 data from the U.S. Department of…

Persistent school segregation means not only that children of different racial and ethnic backgrounds attend different schools but also that their schools are unequal in performance. This study documents the extent of disparities nationally in school performance between schools attended by whites and Asians compared with those attended by blacks,…

This article focuses on how parental school choices affect the degree of racial and academic segregation in charter schools. The research design allows for a direct comparison of the racial and academic conditions of the district schools students exited to the charter schools they entered. Parents choose to leave more racially integrated district…

Achievement data of African American, Hispanic American, and Caucasian students from racially segregated and racially integrated settings in an urban, Midwestern school district were analyzed to determine the effect of racial isolation on achievement within each racial group. In the district studied, achievement of students from segregated schools…

Background/Context: The United States is becoming increasingly racially and ethnically diverse, and increasingly racially isolated across race-ethnic boundaries. Researchers have argued that both diversity and racial isolation serve to undermine the social cohesion needed to bind American citizens to one another and to society at large. Focus of…

Background/Context: Perpetuation theory predicts that attending a racially segregated school paves the way for a lifetime of segregated experiences in neighborhoods, schools, and jobs. Research conducted in the 1970s and 1980s linked racial isolation in high schools with later racial isolation in many social settings among African-American…

Using detailed administrative data for the public K-12 schools of North Carolina, we measure racial segregation in its public schools. With data for the 2005-2006 school year, we update previously published calculations that measure segregation by unevenness in racial enrollment patterns, both between schools and within schools. We find that…

With data for the 2005/06 school year, we update previously published calculations that measure segregation in terms of unevenness in racial enrollment patterns both between schools and within…
