Different Measures of Unemployment: Is There Just One Number to Watch?
You’ve seen the headlines—on June 1, the Bureau of Labor Statistics (BLS) reported that the nation’s unemployment rate was sitting at 3.8 percent, an 18-year low.
To see a lower rate, you’d have to dust off your jetpack and head back to December 1969. (That year, Neil Armstrong set foot on the moon and the Beatles gave their last public performance. So, why not?)
If you prefer your feet firmly planted, check out this FRED® chart, which plots the unemployment rate using data sourced from the BLS.
What does this picture tell us, exactly? And is this the only measure of unemployment that economists watch?
How Do Economists Define Unemployment?
Let’s explain what economists mean when they talk about unemployment. The BLS, which is the federal agency charged with measuring labor market activity, offers these basic concepts:
- The unemployed are people who are jobless, actively seeking work and available to take a job.
- The nation’s official unemployment rate is the number of unemployed as a percentage of the labor force (shown in the FRED chart above).
- The labor force is the sum of employed and unemployed people, age 16 and over.
But, what about a couple neighbors you know?
- Bob, who was let go from his construction job and tried for months to find new employment but is now halting his job search due to poor local prospects.
- Karen, who’s working part time as a tutor because her full-time job as a systems analyst was eliminated.
Based on BLS’ official measures, neither of your neighbors would be counted among the nation’s unemployed. Such nuances are why economists also study alternative measures of unemployment. The BLS tracks these numbers, too, to help gauge the economy’s use of its labor resources.
Different Measures of Labor Underutilization
|Measure||What It Looks at||Seasonally Adjusted Rates (As of May 2018)|
|U-1||Persons unemployed 15 weeks or longer, as a percent of the civilian labor force||1.3%|
|U-2||Job losers and persons who completed temporary jobs, as a percent of the civilian labor force||1.8%|
|U-3||Total unemployed, as a percent of the civilian labor force (official unemployment rate)||3.8%|
|U-4||Total unemployed plus discouraged workers, as a percent of the civilian labor force plus discouraged workers||4.0%|
|U-5||Total unemployed, plus discouraged workers, plus all other persons marginally attached to the labor force, as a percent of the civilian labor force plus all persons marginally attached to the labor force||4.6%|
|U-6||Total unemployed, plus all persons marginally attached to the labor force, plus total employed part time for economic reasons, as a percent of the civilian labor force plus all persons marginally attached to the labor force||7.6%|
In the above examples:
- Bob is a discouraged worker (counted in U-4 through U-6).
- Karen is employed part time for economic reasons (counted in U-6).
