The provided pie chart illustrates the percentage of people who dined at restaurants across four different years, while the line graph displays the quantity of food served in both fast food and sit-down restaurants over the same period.
Overall, it is notable that the number of people preparing meals at home decreased, while the number of meals consumed at restaurants increased over the 30-year period. In addition, eating in fast food restaurants became more popular than dining in sit-down restaurants by 2000.
In 1970, people spent most of their time on cooking at home, and only 10% of the food budget was allocated to restaurants meals. Over the next 10 years, this figure rose slightly to 15% before jumping to 35% in 1990. By the end of the period, dining out was prefered to home meals and accounted for half of the total food budget.
When comparing fast food and sit-down restaurants, the former showed a sharper increase. In 1970, the number of meals eaten in both types of restaurants started at only 20%. However, the figure for fast food restaurants went up dramatically to around 90% in 2000, while that for sit-down restaurants only represented nearly 50% in the same year.
