The pie chart provides data regarding the percentages of food budget spent by the average household on restaurant or homemade meals from 1979 to 2000. Overall, it is clear that at the beginning of the period, the vast majority of families cooked at home, while at the end, the proportions for home and restaurant meals were equal. It is also evident that fast food meals became extremely popular among citizens in the second part of the period.
Focusing first on the percentages of the budgets spent on restaurant or homemade food, between 1970 and 1980, 90% and 85% of money went on home cooking, whereas in 1990, the proportion dropped by approximately 10%. Notably, in 2000, they spent exactly the same sums on eating at home or in restaurants.
Turning to the number of meals in fast food and sit-down restaurants, in 1970, the figures for both of them stayed at 20, which started to increase to approximately 28 and around 35 by 1980, respectively. However, by 2000, the number for fast food meals rose only by 15, whereas for the other category, the figure hit the peak, reaching almost 90.
