during a 28-year period from 1980 to 2008.

Overall

, there were many significant fluctuations during the period.

While

the US government spends a large

amount

of

money

on

health

, the expenditure on general

science

was the lowest.

Besides

, the other fields had a wild fluctuation between 1980 and 2008. It can be clearly observed from the chart that the expenditure on research into

health

was the highest at approximately $8

billion

, which was nearly three times as high as that on general

science

in 1980.

Then

, the spending on

health

research steadily declined to $7

billion

in the following four years before dramatically increasing to reach a peak of over $20

billion

in 2004, which was followed by a slight decrease of over $3

billion

in the final year.

By contrast

, the

amount

of

money

spent on researching general

science

was the lowest during the period with a fluctuation between $2.5

billion

and $5

billion

. In terms of the other categories, there was a moderate growth in the expenditure on space and energy
