Which of the following can result in a decrease in the demand for I-Pods in the short run?

(A) a decrease in the population
(B) a decrease in real household incomes
(C) a decrease in the price of MP4’s
(D) All of the above.

(A) a decrease in the population

Explanation: The population of an area can affect the quantity of goods and services demanded for. As more or fewer consumers enter the market there is a direct effect on the amount of a product that consumers (in general) are willing and able to buy. During population increases, more I-Pods would be sold (increase in demand). When the population of consumers decreases significantly, less sales would be made (decrease in demand) until it increases again.
