Unemployment refers to individuals who are able and looking for work but unable to find a suitable job. It is measured by the unemployment rate which divides the number of unemployed by the total workforce. Unemployment indicates the economic status of a country. The National Sample Survey Organization defines unemployment as a situation where people lack work and actively seek employment or express willingness to work. Common types of unemployment include disguised, seasonal, structural, cyclical, and technological unemployment. Strategies to reduce unemployment focus on increasing investment, diversifying agriculture, promoting labor-intensive industries, and improving skills and mobility.
