The line chart illustrated the expenditure on health, space, energy, general science and the other that the U.S government carried out a research over a period of 28 years.
It is clear that while the spending on space and general science rose, the opposite was true for health and other sectors . It is also remarkable that the amount of money spent on the health sphere was the highest for the most of the period.
In 1980, the expenditure on health was 8 billion, which was significantly higher than the figure for general science, at only 3 billion. Over the following 24 years, the amount of money that was spent on health increased substantially to reach a peak of about 22 billion in 2004, followed by a considerable drop to 17 billion in 2008. By contrast, the spending on general science witnessed some minor fluctuations, about 3 billion to 4 billion during the first 12 years, but later the figure for general science then steadily rose to 5 billion in the next 16 years.
Looking at the other area, it was the sphere that spent the most in 1980 with 7 billion, compared with 5 billion for energy. Over the 20 years, The figure for it still remained stable at 5 billion though it had little changes in that period. The figure for the other sectors and the space were increased in 1980 then slightly dropped at 5 billion in 1984, both of them unchanged in the next 4 years after that the spending on the space escalated to nearly 10 billion. Meanwhile, the amount of money which was spent on the other sectors experienced a significant decrease throughout the last 8 years, ending at 5 billion at the end of the period.
