In this report, the authors identify public schools whose doors are effectively closed to poor children. These institutions--generally found in wealthy urban enclaves or well-heeled suburbs--educate many of the children of America's elite while proudly waving the "public school" flag. But they hardly embody the "common school" ideal. In fact, by exclusively serving well-of children, they are arguably more private--certainly more exclusive--than many elite private schools, which, after all, generally offer at least "some" scholarships to low-income students. The authors wanted the answers to some basic questions. How many of these ""private" public schools" exist nationwide? How many children do they serve? Are they clustered in certain states or metropolitan areas? What are their racial demographics? To find out, the authors dove into the federal government's Common Core of Data for 2007-2008 and started counting. This paper presents their findings. (Contains 8 tables, 4 figures and 8 footnotes.)
