If a country's population grows by 5 percent while total food production grows by 8 percent, what is the likely effect on food availability per person if other conditions remain unchanged?

Answer and explanation

Correct answer: It may increase

Food availability per person depends on the ratio of total food production to total population. To compare the new situation with the old one, production is multiplied by 1.08 and population by 1.05. The new per-person availability is therefore multiplied by \(1.08/1.05\), which is greater than 1. This means each person has more food available on average, assuming other conditions stay unchanged.

Since 8 percent production growth is greater than 5 percent population growth, food production grows faster than the number of people sharing it. Numerically, \(1.08/1.05\approx1.0286\), or about a 2.86 percent rise in per-person availability. Therefore option B is correct. The increase is not necessarily 8 percent, but it is likely positive; it will not be zero or an unavoidable decline.
