This document presents and develops existing statistical data on the education professions. Topics and problems concerning teachers that are examined in detail are: numbers of teachers; institutions in which they teach--including public schools, higher educational institutions, and vocational and technical schools; whether there are sufficient numbers to meet existing needs of pupils; personal and professional characteristics of teachers; and the ways in which persons enter teaching as a career. Statistical tables, which constitute approximately half of the document, are interspersed with text. (Author/RT)
