The graph illustrates the expenditure on different types of fast food—hamburger, fish & chips, as well as pizza—by income groups in the US in 1990. Overall, hamburgers leaded the top as the most bought off type of junk food for all but the low-income group, while pizza remained the lowest in popularity.
People with high earnings had a tendency to buy many more hamburgers—about 42—in comparison to those with low income, who bought just a little less than 15 burgers that year and people with average income sitting at 32 burgers per person.
Fish & chips, on the other hand, were the most popular type of food from the compared list for people with average earnings, as they spent their income on 25 of them per year. Both high and low earners purchased approximately 16-17 of these that year.
Pizza was generally the least favored across all income groups, likely due to its higher price compared to other fast food. High earners were still in the lead purchasing a whopping 19 pizzas annually. From this point on, expenditure declined, as people with average incomes bought only 12 pizzas, while low earners purchased just 7 that year.
In conclusion, the data highlights a clear correlation between income levels and fast-food preferences. While hamburgers were the most popular choice overall, fish & chips stood out among average earners, and pizza remained the least favored option, likely due to its higher cost.
