The correct option is Self-employed.
Explanation
The composition of India's workforce is determined based on the activity status of individuals as recorded by the National Sample Survey Office (NSSO) in its Periodic Labour Force Survey (PLFS). The workforce is broadly categorized into Self-employed, Regular Wage/Salaried Employees, and Casual Labour.
Detailed Analysis:
- Self-employed: This category accounts for the largest share of India's total workforce. According to the PLFS Annual Report (July 2022 - June 2023), the percentage of self-employed persons in the total workforce is approximately 57.3%. This category includes own-account workers, employers, and unpaid helpers in household enterprises.
- Casual wage labourers: This category represents the second-largest share, accounting for approximately 21.8% of the workforce. These workers are engaged in others' farm or non-farm enterprises and receive wages according to the terms of the daily or periodic work contract.
- Regular salaried employees: This group constitutes approximately 20.9% of the workforce. These workers receive regular wages or salaries and typically have better access to social security benefits compared to the other categories.
- Public sector employees: This is a specific subset of the regular salaried category and constitutes a minor percentage of the overall national workforce.
Key Takeaway: The structure of employment in India is dominated by self-employment (over 50%), followed by casual labour and regular salaried employment.
