Read the following statements carefully:
Statement 1: As per the National Sample Survey Organization (NSSO), unemployment is a situation in which all those who, owing to lack of work, are not working, but are seeking work from prospective employers. They express their willingness/availability to work under the prevailing conditions of work and remuneration.
Statement 2: Disguised Unemployment is generally a massive problem in a highly populated country like India.
Statement 1: The NSSO defines unemployment as the situation where people are not working but are actively seeking work and are available to work. This is accurate.
Statement 2: Disguised unemployment, common in rural India, refers to more people working on a task than required, leading to underutilization of labor.
Conclusion: Both statements accurately describe unemployment in the Indian context.
