The three-bar chart show average years of schooling, number of scientist and technicians, and research and development countries. Figures are given for 1980 and 1990.
It is clear from the chart that the figure for industrialised countries are much higher than those for developing countries. Also, the chart shows an overall increase in education, population and science over the period.
People In developing nations attended school for an average of around 3 years, with only a slight increase in years of schooling from 1980 to 1990. On the other hand, the figure for industrialised countries rose from nearly 9 years of schooling in 1980 to nearly 11 years in 1990.
From 1980 to 1990, the number of scientist and technicians in industrialised countries almost double to about 70 per 1000 people. Spending on research and development also saw rapid growth in these countries, reaching $350 billion in 1990. By contrast, the number of science workers in developing countries remained below 20 per 1000 people, and research spending fell from about $50 billion to only 25$ billion.
