Which of the following category of workers is NOT a part of informal sector in India?

none of the above

The correct answer is Option 4: none of the above

We classify workforce into two categories: workers in formal and informal sectors, which are also referred to as organised and unorganised sectors.

All the public sector establishments and those private sector establishments which employ 10 hired workers or more are called formal sector establishments and those who work in such establishments are formal sector workers.

All other enterprises and workers working in those enterprises form the informal sector. Thus, informal sector includes millions of farmers, agricultural labourers, owners of small enterprises and people working in those enterprises as also the self-employed who do not have any hired workers. It also includes all nonfarm casual wage labourers who work for more than one employer such as construction workers and headload workers.
