The bar charts illustrate the average years of schooling, scientists and technicians per 1000 people and also the participation levels in research and development in developing and industrialised countries during 1980 and 1990.

The bar graphs compare the data regarding the mean

years

of schooling, scientists and technicians per 1000 people, and expenditure on research and development measured USD billions, in emerging and developed

nations

in 1980 and 1990.

Overall

, only spending on research in developing

countries

decreased

while

other variables rose in a ten-year timeframe. The average amount of time spent studying at school in both

countries

leveraged where emerging

nations

had a slight increase from nearly above 2

years

in 1980 to almost 4

years

after a decade,

while

industrialised

countries

faced a more significant increase,

initially

slightly above 8

years

to above 10

years

in 1990. Talking about the ratio of scientists and technicians, developed

countries

' ratio jumped from barely above 40 in the 80s to around 70 per 1000 people in the next decade.

On the contrary

, the number of

such

experts in the developing world remained under 20 with a mere increase in 1990.

Lastly

, the disparity in spending on research and development between developed and developing

nations

is very noticeable, with only under USD 100 billion spent in both

years

by emerging

countries

, in comparison with developed

nations

' USD 150 billion expense in 1980 that dramatically rose to double that number in 1990.
