A farmer sells wheat used to make flour and bread. Which demographic would be most useful for him to track in order to improve marketing of his wheat for the next five years?
A. changes in U.S. racial patterns
B. number of births per year
C. changes in U.S. economic status
D. general population growth numbers

C

Explanation:

A farmer would want to look at the economic status of the US because his goal is to sell as much wheat as possible and make the most profit. If he pays no attention to the economy and there's a recession but he still sells his wheat at the normal price, people whose stocks are going down and who are losing money will be unable to, and unwilling to, pay the price. Thus, the farmer must inspect the changing economic statuses of the US to determine the best and most effective way to market out his wheat to the public.

Changes in US racial patterns have no impact on the marketing of the farmer's wheat, so A is incorrect.

The number of births per year is also irrelevant, as is the general population growth numbers because these do not affect the way the farmer will market his crops, so B and D are incorrect.

Hope this helps!

C. changes in U.S. economic status
