According to the Census of India, a ‘Main Worker’ is defined as a person who has worked for 183 days (or six months) or more during the reference period (one year preceding the date of enumeration). A person who worked for less than 183 days is classified as a ‘Marginal Worker’.
The Census of India categorizes the population into Workers and Non-Workers. Workers are further subdivided into Main Workers and Marginal Workers based on the duration of work. This classification helps in understanding the nature of employment and the workforce composition.
The reference period for the Census is the one year preceding the date of enumeration. The classification into Main and Marginal workers provides insights into the regularity and intensity of economic activity.
