The information about the quantity of money which was spent by people with three groups of different incomes per week (in pounds) and about the proportion of fast foods consumed (in gram) in Britain in 1970-1990 is illustrated by the diagrams. Overall, almost all groups of people with different incomes spent more money on hamburgers, and consumption of most items rose over the years.
The first chart shows most people with a high income spent their money on hamburgers at around 45 pounds per week. Followed by pizza and Fish & chips with approximately £19 and £17 respectively. Among average income groups, hamburger is more dominant at about £37. Fish & chips took the second place at around £25. Whereas, pizza with £12 lies on the bottom. The people with low income, fish & chips ranked first which accounts for £17, with hamburger and pizza in the second and the third place recorded at around £14 and £7 each.
The second chart illustrates that the trend for Fish & Chips shows the consistent rise during the period, starting with a slight increase in one decade from 1970, listed at around 90 to 150 grams, and then rose significantly to reach 500 grams in the last period. Likewise, hamburgers show a similar pattern with growth from around 30 to 100 grams in 1970 to 1985 before rising back to 300 grams. Meanwhile, pizza continued to show a decline over the period, from 300 to 200 grams.
