Unemployment is a major problem in Bangladesh. It is defined as a state of being without work and available for work. According to the ILO, the unemployed are those without work but available and seeking work, including those who have lost jobs or left work voluntarily. Unemployment can be voluntary or involuntary, with involuntary types including structural, regional, seasonal, technological, frictional, educated, casual, cyclical, and disguised. Causes of unemployment include population growth, industrial backwardness, lack of skills, limited investment and land, defective education, and abuse of power. Effects are economic and mental stress, decreased demand, social unrest, inability to repay debts, crime, violence, and loss of skills.
