The provided diagrams illustrate the weekly expenditure on various fast foods across different income groups in Britain, alongside an analysis of the consumption trends from 1970 to 1990.
Overall, it is evident that higher-income individuals predominantly allocated greater financial resources toward fast food, with a significant inclination towards hamburgers, while lower-income groups exhibited a marked preference for fish and chips. Furthermore, a notable transformation in consumption patterns can be identified throughout the specified timeframe.
In terms of weekly expenditure, individuals within the high-income bracket exhibited the highest financial commitment, spending just over 40 pence per week on hamburgers, approximately 25 pence on fish and chips, and around 15 pence on pizza. Conversely, average-income consumers allocated roughly 33 pence towards hamburgers, followed by about 25 pence for fish and chips, and a lesser amount of about 12 pence on pizza. Meanwhile, those in the low-income category demonstrated a distinct prioritization of fish and chips with expenditures around 18 pence, contrasting with lower allocations of approximately 14 pence for hamburgers and 7 pence for pizza.
Evaluating the consumption trends from 1970 to 1990 reveals significant shifts in the popularity of different fast foods. Fish and chips initially dominated the market with consumption figures around 300 grams in 1970. However, this figure saw a consistent decline, reaching approximately 200 grams by the mid-1980s, before recovering marginally to just over 220 grams by 1990. In contrast, the consumption of hamburgers surged dramatically from around 80 grams in 1970 to over 500 grams by 1990, surpassing that of fish and chips during the mid-1980s. Similarly, pizza consumption exhibited a steady increase, escalating from about 20 grams to nearly 300 grams within the same period, thereby reflecting changing dietary preferences among the British public.
