The Periodic Labour Force Survey (PLFS) is the principal source of official employment and unemployment data in India, conducted by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI). It was launched in April 2017, replacing the quinquennial (five-yearly) employment-unemployment surveys of the National Sample Survey Office (NSSO), the last of which was conducted in 2011-12. The PLFS was recommended by an expert committee chaired by S. Amitabh Kundu to address the long gap between the older quinquennial rounds and to provide more frequent, policy-relevant labour data. Its first annual report covered the period July 2017–June 2018 and was released in 2019.
The PLFS measures employment using two reference periods and approaches. The Usual Status (US) approach records a person's activity status over the preceding 365 days, while the Current Weekly Status (CWS) uses the preceding seven days. It generates key indicators: the Labour Force Participation Rate (LFPR) — the share of population working or seeking work; the Worker Population Ratio (WPR) — the share actually employed; and the Unemployment Rate (UR) — the share of the labour force seeking but not finding work. The survey design provides quarterly bulletins for urban areas (using CWS) and annual reports covering both rural and urban areas. The survey year runs from July to June. From 2025, MoSPI revised the PLFS methodology to release monthly estimates and expanded sample coverage, reflecting the demand for higher-frequency data.
PLFS data has driven major policy and political debate. The 2017-18 report, leaked before official release, reported an unemployment rate of 6.1 per cent — the highest in 45 years, a finding that became contentious during the 2019 general election period and prompted resignations from the National Statistical Commission. Subsequent reports showed the headline unemployment rate easing and the LFPR rising, with female labour force participation a recurrent point of analysis. The PLFS works alongside other employment indicators such as the EPFO payroll data, CMIE's private estimates, and the Annual Survey of Industries, and is distinct from decennial Census employment data. As of 2026, the PLFS remains the authoritative government benchmark for labour-market trends and feeds into the Economic Survey and NITI Aayog assessments.
For the UPSC examination, PLFS is tested in General Studies Paper III (Indian Economy — growth, development, and employment) and frequently in current affairs and prelims. Candidates should distinguish PLFS from the older NSSO rounds, know its launch year (2017), its conducting agency (NSO under MoSPI), and the precise definitions of LFPR, WPR, and UR with their two reference periods (Usual Status and Current Weekly Status). Prelims questions often pair indicators with definitions or test which body conducts the survey, while mains answers require linking PLFS data to issues like jobless growth, the informal sector, female workforce participation, and the demographic dividend. The distinction between the survey year (July–June) and its quarterly versus annual reporting cycle is a common factual trap.
Example
In 2019, the NSO's first PLFS report (2017-18) recorded India's unemployment rate at 6.1 per cent — the highest in 45 years — triggering controversy ahead of the general elections.
