The three bar charts compare the average years of schooling, numbers of scientists and technicians, and research and development spending between developing and industrialized countries in the years 1980 and 1990.
Overall, there was an upward trend in the levels of participation in education and science. Additionally, the figures for developed countries were much higher than those for developing nations.
In detail, in 1980, developing countries attended school for an average of roughly 3 years. In the following ten years, this figure increased to nearly 4 years on average. As for industrialized countries, the figure for schooling rose from nearly 9 years in 1980 to approximately 11 years in 1990.
The number of scientists and technicians in developing countries just stood at around 15 and nearly 20 people per 1000 people in 1980 and 1990, respectively. Whereas, the number of science workers in industrialized nations almost doubled to about 70 people from 1980 to 1990. In terms of research and development spending, the figure in developing countries stood at $50 billion in 1980 but fell to only about $20 billion in 1990. By contrast, research spending saw rapid growth in industrialized nations, peaking at $350 billion in 1990.
