The bar charts provide information about the average years that people spent in school, the number of scientists and technicians, and the amount of money spent on research and development in both developing and industrial countries in 1980 and 1990. The amount of money spent on research and development and the number of scientists and technicians were greater in the industrialized countries than developing countries in both 1980 and 1990. The average years of schooling had increased from about 9 to 11 years and from about 3 to just below 4 years in 1980 and 1990 in both industrialized and the developing countries respectively.The number of scientists and technicians had gone up in both developing and industrialized countries in 1990 than it was in 1980. It was around 10/1000 people in 1980 then raised to just below 20/1000 people in 1990 for developing countries. In industrialized countries, it increased from just above 40/1000 people to about 70/1000 people. In addition, the amount of money spent on research and development had raised to almost 350 US billion dollars in industrialized countries in 1990 but decreased to nearly 20Us billions in developing countries.Overall, the average years of schooling and number of scientists and technicians had been increased in developing and industrialized countries. While the amount of money spent on research and development had raised in industrialized countries but declined in developing countries.
The three bar charts show average years of schooling, numbers of scientists and technicians, and research and development spending in developing and developed countries. Figures are given for 1980 and 1990.
It is clear from the charts that the figures for developed countries are much higher than those for developing nations. Also, the charts show an overall increase in participation in education and science from 1980 to 1990.
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 scientists and technicians in industrialised countries almost doubled 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.
