Examined were the differences which existed in schools among the following four types of school districts during 1933-34: those including no urban territory; those in large cities of more than 10,000 population; those in small cities of 2,500 to 10,000 population; and those including both rural and urban territories. Data were obtained from the county superintendents' reports. Rural data were from 440 administrative units in counties with no single incorporated places of 2,500 or more population. Urban data were from 340 school systems located in all States, except Florida and West Virginia. Data for Lhe urban-rural school systems were from Maryland, West Virginia, Virginia, North Carolina, Georgia, Florida, Alabama, southern Louisiana, and the mountain area of Utah. A total of 1,047,873 elementary and high school pupils in rural, 4,480,873 in urban, and 356,245 in county-unit schools were involved. Data covered enrollment, attendance, pupil-teacher ratio, school expenditures per pupil, the school term, source of receipts, staff salaries, and value of school properties, debts, and capital outlay. Findings included: average daily attendance per elementary school was 317 pupils in large city systems, 181 in small city systems, 38 in the rural school districts, and 111 in urban-rural systems; large city school systems provided, on the average, the longest school term; and rural schools received a larger percentage of revenue from State sources.
