The three bar graphs illustrate the average years of schooling, number of scientists and technicians, and research development spending on developing and industrialised nations between 1980 and 1990.
Overall, the figure for industrialised countries in all categories was always higher than those for developing countries. Interestingly, spending on research and development in industrialised nations increased significantly, while the remaining was a slight decline.
One of the most significant features of the chart is that people in developing nations took part in school for average of around 3 years, then it only increased slightly in year of schooling from 1980 to 1990. In contrast, industrialised countries spent more average years for education than developing ones, with above 8 years in 1980, rising substaintially to approximately 11 years after decade.
From 1980 to 1990, the number of scientists and technicians had a big change with double climb to nearly 70 per 1000 people in industrialised regions. Besides, spending on research and development showed an enormous growth in these countries, at about $350 billions in 1990. Finally, the number of scientists and technicians had a moderate rise to under 20 per 1000 people, and research spending fell from about $50 billion to only $25 billion in developing ones.
In summary, the data reveals clear regional differences between devloping and industrialised countries, with all of the categories in both types of countries was a significant increase, except spending on research and development in developing nations.
