Last week, we released our research brief on segregation by race and ethnicity in the District of Columbia. The analysis is unique insofar as it includes regular public schools, charter schools, and private schools, thus providing a comprehensive look at segregation in our nation’s capital.
Private schools serve only about 17 percent of D.C.’s students, but almost 60 percent of its white students. This means that any analysis of segregation in D.C. that excludes private schools may be missing a pretty big part of the picture. Our brief includes estimates of segregation, using different types of measures, within the private and public sectors (including D.C.’s large charter school sector). Unsurprisingly, we find high levels of segregation in both sectors, using multiple race and ethnicity comparisons. Yet, while segregation in both sectors is extensive, it is not substantially higher in one or the other.
But one of our most interesting findings, which we’d like to discuss here, is that between 25-40 percent of total citywide segregation is actually found between the public and private sectors. This is not a particularly intuitive finding to interpret, so a quick explanation may be useful.
