Band 9: The chart below shows the amount of money per week spent on fast foods in Britain. The graph shows the trends in consumption of fast foods.

The bar chart compares weekly expenditure on three types of fast food among different income groups in the UK in 1990, while the line graph shows changes in the consumption of these foods between 1970 and 1990 in the same country.

Overall, hamburgers were the most popular fast food, particularly among high-income groups, and their consumption increased significantly over time. In contrast, fish and chips became less popular, while pizza consumption rose steadily during the period.

In terms of expenditure, people with higher incomes spent the most on hamburgers, at around 40-45 pence per person per week. Spending on fish and chips and pizza was much lower, both remaining below 20 pence. For average earners, hamburgers were still the most purchased item, whereas among low-income groups fish and chips slightly exceeded hamburger spending.

Regarding consumption trends, the amount of hamburgers eaten rose dramatically from about 80 grammes in 1970 to over 500 grammes in 1990, becoming the most consumed fast food by the end of the period. By contrast, fish and chips consumption fell from roughly 300 grammes to around 200 grammes. Pizza, on the other hand, showed the opposite pattern, increasing gradually from a very low level to approximately 250-300 grammes in 1990.
