Definition

The unemployment rate is the percentage of the labor force that is unemployed. A person is unemployed if they did not work at all during the survey week, were available to work, and actively looked for a job in the previous four weeks (or are waiting to be recalled from a layoff). The official headline rate is called U-3.

How it works

Unemployment rate = unemployed ÷ (employed + unemployed) × 100

The numbers come from the Current Population Survey, a monthly interview of about 60,000 households, released with the jobs report. People who are not working and not looking – retirees, students, parents at home, or people who have given up – are outside the labor force and not counted at all. That is why the rate can fall when discouraged job seekers stop searching.

The broader U-6 rate adds people who want a job but have stopped looking, and part-timers who want full-time work. It is always several points higher than U-3.

Example

Imagine a town of 10,000 adults. 6,000 have jobs, 300 have none but are looking, and 3,700 are retired, studying or not looking. The labor force is 6,300 and the unemployment rate is 300 ÷ 6,300 = 4.8%. If 100 of the job seekers give up, the rate drops to 200 ÷ 6,200 = 3.2% – although nobody found a job.

Common mistakes

  • “Unemployment counts everyone without a job.” Only those actively looking. Someone who stops searching leaves the labor force and is no longer counted as unemployed.
  • “It is based on unemployment benefit claims.” It comes from a household survey. Many unemployed people never claim benefits, and the weekly jobless claims report is a separate series.
