The bar chart demonstrates the expenditure by three income groups on three types of fast foods namely hamburger, fish & chips and pizza in the year 1990.
Overall, it is clear that high and average earners can afford to spend significantly more money on fast foods than those with low income. Additionally, Hamburger registered the highest consumption out of the 3 items studied.
People with high income tended to spend the most money on hamburger, at about 43 pence per week, while this was lower in average income earners, at 32 pence per week. A similar pattern was witnessed in the consumption of pizza among high and average income earners, which registered 19 and 11 pence per week, respectively. In contrast, people with average income witnessed a higher expenditure on fish & chips, at 25 pence per week, compared with 16 pence per week for high-income earners.
In the low-income group, people spent more on fish & chips than on hamburger and pizza. However, spending was relatively low, at just 17 pence per week on fish & chips, 14 pence per week on hamburger and 6 pence per week on pizza.
