Scientists and technicians were possibly higher in number, in advanced countries, than those in the developing countries . They were 10 and 18 per 1000 people in the developing countries, in the other hand they were 40 and above 60 per 1000 people in the advanced countries, in 1980 and 1990 respectively.
In 1990, in spite of spending on research and development grew rapidly from above 100 billions dollars to above 300 billion dollars. It decreased in the developing countries from 50 billion dollars to a nearly 20 billion dollars amount.

Hello!

Not a bad report, but you have missed a golden opportunity to show off your English skills by using some comparative language, e.g. double, ten times higher, 50% greater. In addition, you haven't used enough words like 'increase' to indicate changes. Grammar is reasonable, with many mistakes, but none that affect meaning. Overall, vocabulary is the aspect of this report that requires improvement.

All the best,
David
