Employment and Unemployment Surveys (EUS) conducted by NSSO were the primary source of labour market data at the National and State levels in India. Regular EUS were conducted quinquennially (after every five years) since 1972.
Considering the importance of the availability of labour force data at more frequent intervals, the Ministry of Statistics and Programme Implementation constituted a committee on Periodic Labour Force Survey (PLFS).
Now, National Statistics Office (NSO) is conducting PLFS to produce annual statistics of employment and unemployment characteristics for both rural and urban areas, along with quarterly estimates for urban areas. The first annual report based on the data collected in PLFS during July 2017- June 2018 was published in May 2019.
As per the PLFS 2017-18, 6.1% of India’s labour force are unemployed.
The PLFS was designed with two major objectives for the measurement of employment and unemployment.
The first was to measure the dynamics in labour force participation and employment status in the short time interval of three months for only the urban areas.
The second was for both rural and urban areas, to measure the labour force estimates on key parameters on an annual basis such as labour force participation rate, worker population ratio etc.

Answer: Option B. -> Number of persons in the labour force as a percentage of working age population
Answer: (b)India’s labour force is around 50 crore which includes people who are employed or not employed but actively searching for job. Working age population is more than the labour force because a lot of persons may not be part of labour force but are in working age population for example house wives or a person taking a break from his job. Employment rate is defined as the number of people employed as a percentage of labour force. Labour force participation rate is defined as the number of persons in the labour force as a percentage of working age population.
