Frictional unemployment is short term.
It results from a lack of information about job opportunities and the economy's inability to match jobseekers with jobs quickly, and refers primarily to people looking for their first jobs or those who quit one job to look for another.

Structural unemployment also includes joblessness caused by discrimination of any type or imbalances between sections of the country where jobs are available and where the jobless reside.
