The three charts illustrate average year of schooling, scientists and technicians per thousand people and spending on research and development in developing and industrialized countries in two years.
Overall, developed nations are more advanced than developing nations in all the three categories in both years. Spending on research and development is the least in developing states.
In 1980, average year of schooling in developing world is approximately 3 which is three times less than industrialized countries. In the same year, it has roundabout ten scientists and technicians, four times less than developed countries and the spending on research and development is just above $50 billion, however that of advanced countries has almost $150 billion.
In 1990, this number increased to just below 4 for developing and over 10 for developed states. Developing countries have almost the same number of scientists and technician with a minor increase. This has approximately doubled for Industrial nations. The spending on research decreased for non-industrial states and reached to $350 billion for industrial nations.
