rises. As a household's income increases, the percentage of income spent on
food decreases while the proportion spent on other goods (such as luxury
goods) increases.
For example, a family that spends 25% of their income on food at an income
level of $50,000 will spend $12,500 on food. If their income increases to $
100,000, it is not likely that they will spend $25,000 (25%) on food, but
will spend a lesser percentage while increasing spending in other areas. |
