Data on educational enrollment, attainment, and expenditures, covering each of the 24 members of the Organisation for Economic Cooperation and Development plus Yugoslavia, illustrate the development of each country's educational system. The data, in both English and French, are arrayed in 154 tables and divided into five sections. The first section delineates the scope of formal education for 1970 and 1976, covering ages of educational entry and exit by sex and average years of education by both age and sex. The second section details enrollment by sex at all educational levels from 1965 to 1977, as well as university enrollment by field of study and by sex. It also provides data on average annual growth rates of both school-age population and enrollment. New entrants to university and nonuniversity higher education programs are enumerated by sex in section three for the years 1965-1977. The fourth section lists each country's full-time enrollment rates by age, sex, and educational level for 1970 to 1976. The final section examines the growth of public expenditures at all levels of public education from 1960 to 1977. In addition, Gross National Products are compared with educational expenditures by educational level for 1970 and 1975. (RW)
