The data illustrate weekly spending on fast food in Britain and and highlight how consumption habits developed over time. Overall, higher-income groups spent more money on fast food than lower-income groups, with hamburgers accounting for the highest expenditure. Over time, consumption of hamburgers and pizza increased, while fish and chips generally declined.
In the high-income group, people spent the most on hamburgers, as just over 40 pence per person per week, which was considerably higher than spending on the other types of fast food. In the average-income group, hamburgers were again the most popular meal, people spent about 33 pence each week.
By contrast, among low-income earners, the most popular fast food were fish and chips. People spent on them approximately 18 pence per week.
