The piecharts show changes in American spending patterns between 1966 and 1996.
Food and cars made up the two biggest items of expenditure in both years. Together they comprised over half of household spending. Food accounted for 44% of spending in 1966, but this dropped by two thirds to 14% in 1996. However, the outlay on cars doubled, rising from 23% in 1966 to 45% in 1996.
Other areas changed significantly. Spending on eating out doubled, climbing from 7% to 14%. The proportion of salary spent on computers increased dramatically, up from 1% in 1996 to 10% in 1996. However, as computer expenditure rose, the percentage of outlay on books plunged from 6% to 1%.
Some areas remained relatively unchanged. Americans spent approximately the same amount of salary on petrol and furniture in both years.
In conclusion, increased amounts spent on cars, computers, and eating out were made up for by drops in expenditure on food and books.
