The chart illustrates the volume of money weekly spent on junk foods in Britain by three different income groups. Whereas the graph displays the changes in the use of fast food between 1970 and 1990.
From the bar chart, it is clear that high income earners consumed considerably more fast food than other income groups, spending more than twice as much on hamburgers (43 pence per person per week) than pizza or fish and chips (both under 20 pence). Average income earners favoured hamburgers, spending 33 pence per person per week, followed by fish and chips at 25, and then pizza at 15. While low income earners appear to spend less than other income groups on fast food, though fish and chips remains their most popular fast food, followed by hamburgers and pizza.
From the graph we can see that in 1970, fish and chips were twice as popular as hamburger and pizza being at that time the least popular fast food. Consumption of hamburger and pizza rise steadily over the 20 year period to 1990, while fish and chips were in decline over that same period, with slight increase in popularity since 1985.
