Calculating the Real Unemployment Rate

The BLS calculates the official unemployment rate, U-3, as the number of unemployed as a percentage of the civilian labor force. The civilian labor force consists of employed workers plus the officially unemployed, those without jobs who are available to work and have looked for a job in the last 4 weeks. Applying the data found in Table 2 yields an official unemployment rate of 9.1%, or a seasonally adjusted rate 9.4% for April 2009.

Accounting for the large number of marginally attached workers and those working part-time for economic reasons raises the count of unemployed to 24.0 million workers for May 2009. Those numbers push up the U-6 unemployment rate to 15.9% or a seasonally adjusted rate of 16.4%.

The comprehensive U-6 unemployment rate adjusts the official rate by adding marginally attached workers and workers forced to work part time for economic reasons to the officially unemployed. To find the U-6 rate the BLS takes that higher unemployment count and divides it by the official civilian labor force plus the number of marginally attached workers. (No adjustment is necessary for forced part-time workers since they are already counted in the official labor force as employed workers.)

These figures dramatically understate the true extent of unemployment. First, they exclude anyone without a job who is ready to work but has not actively looked for a job in the previous four weeks. The Bureau of Labor Statistics classifies such workers as “marginally attached to the labor force” so long as they have looked for work within the last year. Marginally attached workers include so-called discouraged workers who have given up looking for job-related reasons, plus others who have given up for reasons such as school and family responsibilities, ill health, or transportation problems.

Second, the official unemployment rate leaves out part-time workers looking for full-time work: part-time workers are “employed” even if they work as little as one hour a week. The vast majority of people working part time involuntarily have had their hours cut due to slack or unfavorable business conditions. The rest are working part time because they could only find part-time work.
