This report presents the statistics of public schools in cities for the school year 1923-24. The cities are grouped according to the population groups as set forth by the Bureau of the Census. The various tables describe these groups with respect to size. Every city in Group I (cities of 100,000 population or more) made a report. Groups II (cities of 30,000 - 100,000 population) and III (cities of 10,000 - 30,000 population) are 98 per cent complete. The degree of completeness is due largely to the fact that some cities were visited by field agents of the bureau, who obtained many reports by personal solicitation and collaboration. Careful estimates have been made for cities which failed to report. Summary tables are given by States for cities in Group IV (cities of 2,500 - 10,000 population). (Contains 14 tables.)
