A marginal worker is a person who works for ----------- in a year.

The correct answer is Option (2) → less than 183 days

The Census divides workers by the length of their work. A marginal worker works for less than 183 days (six months) in a year, while a main worker works for at least 183 days. So ‘for 183 days’ or more makes a person a main worker.

Tip: This definition comes from a small box printed beside the main text. NTA sets questions from such boxes, tables and maps too, so read them as carefully as the paragraphs.
