Although trends in the racial segregation of schools are well documented, less is known about trends in income segregation. We use multiple data sources to document trends in income segregation between schools and school districts. Between-district income segregation of families with children enrolled in public school increased by over 15% from…

We estimate male-female test score gaps in math and English language arts (ELA) for nearly 10,000 U.S. school districts using state accountability data from third- through eighth-grade students in the 2008-2009 through 2015-2016 school years. We find that the average U.S. school district has no gender achievement gap in math, but there is a gap of…

We use data from multiple national surveys to describe trends in private elementary school enrollment by family income from 1968 to 2013. We find several important trends. First, the private school enrollment rate of middle-income families declined substantially over the past five decades while that of high-income families remained quite stable.…

We use data from multiple national surveys to describe trends in private elementary school enrollment by family income from 1968-2013. We note several important trends. First, the private school enrollment rate of middle-income families declined substantially over the last five decades, while that of high-income families remained quite stable.…

Researchers examined enrollment and family income data from the past 50 years at Catholic, other religious, and nonsectarian private elementary schools (that is, schools serving grades K-8). The study used data on families' incomes and elementary-school choices from the decennial census, Current Population Survey, U.S. Department of Education…

Has the gap in average standardized test scores between students from high- and low-income families widened, narrowed, or remained stable over the last 3 decades? The question is important both because the achievement gap is measure of how (un)equally educational opportunities are distributed in the US, and because the disparity in educational…

Although trends in the racial segregation of schools are well documented, less is known about trends in "income" segregation. We use multiple data sources to document trends in income segregation between schools and school districts. Between-district income segregation of families with children enrolled in public school increased by over…

We estimate racial/ethnic achievement gaps in several hundred metropolitan areas and several thousand school districts in the United States using the results of roughly 200 million standardized math and reading tests administered to public school students from 2009-2013. We show that achievement gaps vary substantially, ranging from nearly 0 in…

In a recent paper, Reardon found that the relationship between family income and children's academic achievement grew substantially stronger in the 1980s and 1990s in the United States. We provide an international context for these results by examining the income-achievement association in 19 other Organisation for Economic Co-operation and…
