Overall, spending in pounds on hamburgers decreases as income decreases, although interest in this food has been increasing over time.
When examining, the amount of money spent on specific products, hamburgers were the most popular among high-income individuals, with spending at £42. This amount sharply declined for those with middle incomes, dropping to £16 for low-income individuals. Pizza followed a similar trend of decreasing expenditure as income decreased, with low-income spending at £7. Fish and chips, on the other hand, was the most consumed product among middle-income individuals, who spent £25.
Notably, interest in hamburgers and fish and chips increased, especially after the 1980s, reaching around 500 and just under 300 respectively by the mid-1990s (although hamburgers were not as popular among low-income individuals). However, interest in fish and chips gradually declined over the twenty years, finishing in 1990 at just over 200.
