This handbook was compiled to assist OECD Member countries in the long term development of their educational statistics and to provide them with a basis of comparison for the collection of internationally comparable statistics useful to educational planners. Recent methodologica" approaches to long term planning are also discussed. The statistics considered are those required to project in the medium and long term the main magnitudes in the educational system--pupils, graduates, teachers, buildings, costs, and expenditures. The chapter headings present a clear picture of exactly which aspects of educational planning are included: (1) Elements of an educational flow model, (2) sociological aspects, (3) manpower requirements, (4) an integrated conceptual framework, (5) the costs of education--methods of analysis and projection, (6) a statistical tabulation scheme, (7) the collection and processing of data, (8) international comparisons, and (9) directions for further work.
