This investigation is an attempt along the lines of the above studies, yet more intensively, to survey the social, economic, and educational characteristics of a single secondary school population,-that of Cheltenham Township Public School System. The study by Counts published in 1922, showed that in four American cities, the secondary school population was of a highly selective nature. In his study published in 1916, Holley pointed out in much detail certain facts showing the relationships between the persistency of children in school and their home conditions. Educators have for a long time felt the need for knowing something about the immediate social and economic environment of the pupils in our schools.
