This report presents the statistics of city public schools for the school year 1917-18. An attempt has been made for the first time to secure statistics from all cities which had a population of 2,500 or over in 1910. The cities have been divided into five groups: Group I, including all cities with a population of 100,000 and over; Group II, all cities having a population of 30,000 or over but less than 100,000; Group III, all cities with a population of 10,000 or over but less than 30,000; Group IV, all cities with a population of 5,000 or over but less than 10,000; and Group V, all cities having a population of 2,500 or over, but less than 5,000.
