Question

Quizplus · Accepted Answer

The adult population can be divided into three categories - employed, unemployed, and not in the labor force. Therefore, the sum of employed, unemployed, and not in the labor force should be equal to the adult population. Option C includes all three categories, and therefore, is the correct answer. Option A only includes employed and unemployed, which is not enough to cover the total adult population. Option B includes labor force, which is a subset of employed and unemployed, and therefore, will not cover the entire adult population. Option D includes all four categories, but it includes labor force, which, again, is a subset of employed and unemployed, and therefore, is not needed to calculate the total adult population.
