What type of unemployment is caused by a lack of skilled workers?

Structural unemployment occurs when there is a mismatch between available jobs and the skills of workers. This is exactly the case when there is a lack of skilled workers in the economy.

Cyclical unemployment (A) arises during economic downturns.

Frictional unemployment (C) is temporary, due to workers moving between jobs.

Seasonal unemployment (D) arises in industries affected by seasonal patterns (e.g., agriculture, tourism).
