The Research and Development Statistics (RDS) database, published annually, provides recent statistics and back-series on the resources devoted to R&D in OECD countries and selected non-member economies (Argentina, People’s Republic of China, Romania, Russian Federation, Singapore, South Africa, and Chinese Taipei). These data include final or provisional results as well as forecasts provided by government authorities. The statistical series are available from 1981 onwards and cover R&D expenditure by source of funds and type of costs, R&D personnel by occupation, gender, and field of science, and a wide range of other breakdowns.
