Although student segregation by race and ethnicity is well documented in U.S. public schools, the body of evidence on the related outcome of economic school segregation (e.g., by income) is considerably smaller (Reardon and Owens 2014).
In general, economic segregation of students is increasing nationally over the past few decades, both between districts and between schools (Owens et al. 2014). It is inevitable that these aggregate trends vary widely by state, metropolitan area, and district. We were curious as to the situation in New York City, the nation’s largest district, but were unable to find any NYC-specific results, particularly results that included different types of segregation measures.
We therefore decided to take a quick look ourselves, using data from the NYC Department of Education. The very brief analysis below uses eligibility for subsidized lunch (free and reduced-price lunch, or FRL) as a (very) rough income proxy, and segregation is measured between district schools only (charters are not included) from 2002 to 2015. In the graph below, we characterize within-district, between-school segregation using two different and very common approaches, exposure and dissimilarity.
