Please check my writing part 1 (first time on this forum)

The bar charts illustrate the difference in the number of school yeas, scientists, technicians and the amount of money invested into science between developing and developed countries group in the years of 1980 and 1990.It is clear that all figures experienced an upward trend from 1980 to 1990, with the exception for money invested in research and development in poor countries. During the same period, we can see that the figures regarding industrialised countries were all higher in comparison with those from their counterparts.As can be seen from the first chart, in 1980, people from third-world-country spent nearly 3 years studying, while the number of those from developed countries stood at around 9 years. 10 years later observed increases in these figures of both countries, which registered around 4 and 10.5 years respectively.In terms of science, while the number of people whose jobs relating to science increased slightly to around 19 per 1000 people in 1990, there was a surge in the figures for developed countries, which reached 70 per 1000 people. Governments in industrialised countries invested a vast amount of money, which ranging from 150 to 360 billion dollars over 10-year-period, whereas the contrast trend can be seen in their counterparts, whose figures fell by a half during the same period.
