The provided charts illustrate changes in household food expenditure and dining habits between 1970 and 2000. Overall, there was a clear shift towards eating out, with fast-food consumption becoming the dominant trend by the end of the period.
In 1970, only 10% of the average family's food budget was spent on restaurant meals. This figure grew steadily to 15% in 1980 and 35% in 1990, eventually reaching 50% by 2000. This indicates that half of the total food expenditure was dedicated to dining out by the turn of the millennium.
Regarding meal frequency, both fast-food and sit-down restaurant meals started at 20 per year in 1970. By 1980, sit-down meals had risen to 34 per year, surpassing fast-food meals, which stood at 28. However, this trend reversed dramatically thereafter. By 1990, fast-food consumption surged to 55 meals per year, while sit-down meals reached 45. This gap widened further by 2000, with fast-food meals climbing to 85 per year, compared to only 49 for sit-down restaurants. Consequently, fast-food became the preferred choice for dining out, significantly outpacing traditional sit-down establishments.
