12. The U.S. Census Bureau surveys 60,000 households in the United States every month. Working-age population: people age 16-65 Labor force: all workers (age 16-65) who are either employed or unemployed. Employed person: someone (age 16-65) who has a job outside the home or a paid job inside the home. Unemployed person: a person (age 16-65) who does not have a job and is looking for work. Unemployment rate: the percentage of workers (labor force) who are unemployed. How Is Unemployment Measured?

How Is Unemployment Measured?

25. Four types of unemployment: Natural unemployment Cyclical unemployment Frictional unemployment Structural unemployment

26. Natural unemployment rate: the unemployment rate that exists when there is neither a recession nor a boom and real GDP is equal to potential GDP. Cyclical, Frictional, and Structural Unemployment

27. The change in the unemployment rate above the natural unemployment rate is called cyclical unemployment because it is a short-term fluctuation caused by recession. The natural unemployment rate is caused by a combination of frictional and structural unemployment. Cyclical, Frictional, and Structural Unemployment
