over population is the main cause for unemploiment

Over population obviously affect the employement level but it doesnot affect compleatly main thing which affects unemployment is the illetracy..if a person do not have knowledge then he can not servive....so we have to be aware.

That may be a part of it. However, I know of several unemployed people that are simply too lazy to get a job and work. Or they think they are too good for a minimum wage job and choose not to work. Where I live there are plenty of jobs available although they are low paying. If a person wants to work, they can.
