The provided three bar charts illustrate information about how many students enrolled in schooling and the scientific involvement in both developing and industrialized countries in 1980 and 1990.
Overall, what stands out from the charts is that industrialized nations have the highest percentages of education, however both countries experienced a slightly increase in average years of schooling and number of scientists throughout the period in question.
Looking at the details, industrialized countries far exceeded the corresponding developing ones, reaching above 10 years of schooling in 1990. Similarly, studying years in developing countries were about 3 years, whereas they were three times higher in developed ones in 1980.
In terms of science, number of scientists in developing countries witnessed a minimal rise per 1000 people, in contrast, this number climbed significantly when compared to industrialized nations over a decade period. This, in turn, leaded to a dramatic rise in the amount of money which spent on research and development in advanced ones, standing at nearly 350 billion dollars in 1990. However, it slightly decreased in developing countries over the same period.
