The given chart displays three bar graphs comparing information between developing and industrialized countries in terms of the average year of schooling, the number of scientists and technicians per 1000 people and the total expenditure in research and development in the years 1980 and 1990.
It is clear that industrialized countries witnessed a dramatic rise in all three categories, while developing countries increased merely with notable decline in research and development expenditure. Notably, the figure for industrialized countries shared the highest numbers in terms of three categories.
Looking at the average years of schooling, in 1980, developing countries spent just over 2 years on researching, before rising to about 3 years in 1990, while the figure for industrialized countries saw a notable change in spending years; it increased from just over 8 years in 1980 to approximately 10 years in 1990. Although both developing and industrialized countries saw an increase in the numbers of scientists and technicians per 1000 people, the latter one drifted swiftly from 40 people to roughly 70 people in 1990.
Moving on the investment in research and development, developed countries’ spending was lower than industrialized countries’. The former countries stood at almost 50 billion, before felling into only 20 billion, whereas the latter countries spent about 170 billions in 1980 and it increased dramatically by 200 billions.
