Write a report for a university lecturer describing the information shown below.
The bar chart shows how much money was spent on fast foods per week in the UK over a span of 20 years from 1970 to 1990 while the graph reveals the trend of fast food consumption over the same period of time.
As we can see from the chart, the weekly expenses of people of different income levels on hamburgers and fish and chips were relatively higher than that on pizza. The graph indicates that while hamburger and pizza consumption both revealed a general trend of increase, fish and chips showed a trend of fluctuation.
First, the weekly average expenses of high-income people and middle-income people were 42 pence and 33 pence respectively, a lot higher than that of low-income people which was 14 pence. As for fish and chips, high-income people spent relatively less, only 17 pence, but the expenses of middle-income and low-income groups reached 25 pence and 18 pence, much higher than their expenses on pizza which stood at 12 pence and 8 pence respectively. What is worth mentioning is the amount of money spent on pizza by high-income people which showed only 20 pence, 2 pence more than their expense on fish and chips.
Second, starting from averagely 85 grams per week in 1970, people’s consumption of hamburgers gradually grew to 100 grams in 1975 and was then followed by a faster growth, reaching more than 200 grams in around 1983. From then on, the growth gained a stronger momentum, hitting the peak across the board at 550 grams in 1990.
Third, the consumption of pizza revealed a similar trend of growth as that of hamburgers and could also be clearly cut into three periods, though the growth rate was not that fast. It rose slowly from 40 grams per week in 1970 to 80 grams in 1980 and then grew faster from 80 grams in 1980 to 130 grams in 1985. From 1985, the growth rate was even faster and we see a big increase from 130 grams to 280 grams.
Fourth, the consumption of fish and chips showed three changes in the general trend of fluctuation. From 1970 to 1975, it dropped slowly from the original 300 grams per week in 1970 to 280 grams in 1975. Later on, from 1975 to 1985, it dropped a little bit faster when it fell from 280 grams to 200 grams. From then on, it began to rise gradually and till 1990, it had climbed back to 240 grams.
To sum up, the consumption of the three above mentioned fast foods in Britain showed certain rises and falls as illustrated in the chart and graph over the designated 20 years.
