How is the unemployment rate computed, and what does it represent?

• A. Unemployment rate = (unemployed / labor force) × 100; it represents the share of the labor force without work but actively seeking it.
• B. Unemployment rate = (unemployed / population) × 100.
• C. Unemployment rate = (unemployed / population aged 16 and over) × 100.
• D. Unemployment rate = (employed / labor force) × 100.

Answer: (A)

The key idea here is what the unemployment rate actually measures and who counts in its calculation. It looks at the portion of people who are in the labor force (those who are either employed or actively seeking work) who are not currently working but are actively looking for a job. The rate is computed by taking the number of unemployed people, dividing by the labor force, and multiplying by 100.

This setup matters because the labor force is not the same as the total population. People who are not in the labor force—students, retirees, homemakers, discouraged workers, and others not seeking work—aren’t counted as unemployed, so they don’t appear in the calculation. That’s why dividing by the total population (or by population 16 and over) would misstate how tight or slack the job market is. Similarly, dividing employed by the labor force would give the share of the labor force that is employed, not the share that is unemployed.

So the correct approach—unemployed divided by labor force, times 100—expresses the share of those capable of working who actually cannot find a job, which is what the unemployment rate represents.
