The vertical bar graph depicts the expenditure on fast foods by different income groups in Britain, and the line graph shows the trends in consumption of fast foods from 1970 to 1990.
The first graph shows that high-income earners consumed considerably more fast foods than the other income groups. They spent more than twice as much on hamburgers (43 pence per person per week) as on fish and chips or pizza (both under 20 pence). Average income earners spent 33 pence per person per week on hamburgers, which was the maximum they spent on any given fast food.
Furthermore, low-income earners spent less than other income groups on fast foods, though fish and chips remained their most popular fast food, followed by hamburgers and pizza. From the line graph, in 1970, fish and chips were the most popular fast food whereas burgers and pizza were the least popular.
Overall, there was a sharp rise and gradual decline in the consumption of hamburgers, pizza, and fish and chips respectively over the 20 years.
