The two pie charts above give information about the change of the spending on 6 fundamental aspects of life in U.S from 1966 to 1996.
It is noticeable that the proportion of 3 parts, namely Cars, Restaurants and Computers, increased during the period. Specifically, the expenditure on Cars rose sharply from 23% to 45%, becoming the largest in 1996. Similarly, the percentage of Restaurants also doubled. In addition, Computers, which took up the smallest proportion only at 1% in American budget of 1966, soared up by 10 times to 10% by 1996.
For the rest 3 areas, however, the 3-decade period saw an opposite downward-trend. For example, in terms of Food which played a dominant role in consumption in 1966, there was a slump from 44% to only 14%. This was followed by Patrol and Furniture, in both of which a slight drop was found. In comparison, Books cost least money in 1996, which amounted to merely 1% in total, only one-sixth of relevant spending in 1966.
In conclusion, increased amounts spent on cars, computers, and eating out were made up for by drops in expenditure on food and books.
