Data for the figures presented in this feature come from three sources measuring school and program enrollment by race or ethnicity nationally. The first is the National Survey of Early Care and Education, a nationally representative study of center- and home-based early childhood programs conducted in 2012. The study draws on integrated surveys of providers and households to offer comprehensive information on early childhood program use and availability. Our analyses leverage public-use center and home-based provider files and incorporate sampling weights and related information to support nationally representative estimates. We restrict all analyses to programs serving at least five children to ensure the possibility of integration. To supplement these data, we use additional data from the Common Core of Data and the Private School Universe Survey, both from the National Center for Education Statistics. (author abstract)
