the roughly 10 percentage-point increase from the U3, U4,

This formulation of the unemployment rate can cause 
confusion because the size of the labor force, employment, 
and unemployment can all change simultaneously. For

certain amount of churn in the labor force as individuals 
move from one employer to another. 
Cyclical unemployment results from the normal ups and 
downs of the economy, often referred to as the business 
cycle. As the economy slows or enters a recession, firms 
reduce hiring or lay individuals off and cyclical 
unemployment rises. When the economy grows, firms hire 
and cyclical unemployment falls. Short-term deviations are 
mostly attributable to cyclical factors, and are difficult to 
predict, as was the case with the COVID-19 pandemic. 
When the economy is operating at a sustainable level given 
its available inputs, cyclical unemployment is zero and the 
unemployment rate is roughly equal to the sum of structural 
  and frictional unemployment. This is referred to as the
