The given bar charts compare the educational involvement of students in terms of total years of education and their participation in science-related subjects in developing and industrialized countries from 1980 to 1990.
Overall, the amount of schooling time and the proportion of scientists and technicians increased in both types of countries. Although the amount of money invested in research and development in industrialized countries rose, that of developing countries decreased.
From 1980 to 1990, there was an increase in the figures for schooling time in industrialized countries from approximately 8 years to above 10 years. Also, the percentage of scientists and technicians increased by over 20 per 1000 people over a 10-year period. The amount of money spent on research and development was approximately 150 billion in 1980 and then increased rapidly to about 300 billion USD in 1990.
Over the same period, the figures for schooling time in developing nations increased from over 2 years to below 4 years in just 10 years. By contrast, the percentage of scientists and technicians remained below 20 per 1000 people. On the other hand, the year 1990 witnessed a significant decline in the amount of budget spent on Research and Development in these countries, dropping from 50 billion to about 20 billion USD.
