The pie charts reveal differences in UK spending patterns related to seven categories measured in percentages between 1981 to and 30 years later, 2001. As an overall trend, the highest spending in 1971 definitely centered on Food and at that time people did not really focus on computers which took the bottom position in spending. The basic trends for 2001 reveal that Cars as the highest spending category, while it seems that the residents choose to spend a minuscule amount on books in this year. Together Food and Cars comprised over half of the household spending in the UK with Food accounting for 44% of spending in 1971 and Cars at 22%. However, the outlay on cars doubled in 2001, rising from 22% in 1971 to 43% in 2001, while Food dramatically fell by 30% from 1971. It appears that Petrol remained fairly consistent over the 30 year period with only a 2% drop. Other areas also changed significantly with spending on eating out doubling, climbing from 7% to 14%. The proportion of salary spent on computers increased dramatically, up from 2% in 1971 to 12% in 2001. However, s computer expenditure rose, the percentage of outlay on books plunged from 6% to 1%.
