NOTE: Data include all 50 states, the District of Columbia, Puerto Rico, four outlying areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands), the Bureau of Indian Education, and the Department of Defense dependents schools (overseas and domestic). How to read this table: Using the City of Chicago School District 299 as an example, the table shows that the smallest 25 percent of regular schools have a pupil membership of 342 or less, and largest 25 percent have a membership of 764 or more. If all the regular schools in the City of Chicago School District were listed by size, the school at the midpoint on the list (the median) would have 526 pupils in membership. Dividing all City of Chicago School District students in regular schools by the number of such schools yields a mean, or average, size of 662.9 students.
