Our system will evaluate the answer based on this AI-generated description.
The image shows three bar charts comparing the average years of schooling, the number of scientists and technicians per 1000 people, and the spending on research and development in developing and industrialized countries in 1980 and 1990. In the first chart, the average years of schooling in developing countries increased from 2 to 3, while in industrialized countries it increased from 8 to 9. In the second chart, the number of scientists and technicians in developing countries rose from 20 to 30 per 1000 people, while in industrialized countries it increased from 70 to 90. In the third chart, the spending on research and development in developing countries jumped from 50 to 100 US dollars, while in industrialized countries it rose from 300 to nearly 350 US dollars.
Given the complexity of the image, the above description may not be entirely accurate.

The bar charts compare the amount of educated population in developing and industrialised countries in 1980 and 1990.
Overall, it is clear that the trend for each charts, average years of schooling, density of scientists and technicians, investment on research and development, showed a significant growth, except for developing regions.
With regard to average length of schooling, in developing countries, people’s average educational attainment was only 3 years in 1980, which slightly increased to around 3.5 years by 1990. Comparing to industrialised countries, there saw a relatively obvious growth, from 8.5 years to 10.5 years.
In terms of the density of scientists and technicians, the figure significantly rose in 1990, at 70 per 1000 people, which was almost twice more than in 1980. Likewise, the amount of funding that industrialised countries committed to research and development surged dramatically by 200 billion, reaching 350 billion. In contrast, developing countries saw no growth in this sector; instead, they reduce their funding allocated for this purpose.
