Periodic Labour Force Survey (PLFS)

Periodic Labour Force Survey (PLFS) is a large‑scale, continuous household survey conducted by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation. It replaces the erstwhile Employment‑Unemployment Survey (EUS) and furnishes the most up‑to‑date, internationally comparable estimates of employment, unemployment and labour‑force participation for India’s urban and rural economies. By adhering to International Labour Organization (ILO) definitions and delivering quarterly urban and annual rural releases, PLFS supplies policymakers, researchers and businesses with a granular, time‑sensitive picture of the nation’s labour market dynamics.

Historical Background

The transition from the EUS to PLFS was formalised in the 2017‑18 statistical programme, when the NSO announced a shift to a “periodic” rather than “annual” framework. The first PLFS round covered the financial year 2017‑18 and was released in March 2019, marking a departure from the 16‑year run of the EUS that had begun in 1999‑2000. The change was driven by the need for more frequent data, finer geographic granularity, and alignment with the ILO’s Labour Force Survey (LFS) standards that many advanced economies already employ.

Survey Design and Methodology

PLFS employs a stratified, multistage sampling design drawn from the 2011 Census of India, targeting roughly 100 000 households (about 150 000 individuals) each year. Urban areas are surveyed quarterly, with each quarter covering a fresh sample of approximately 25 000 households, while rural areas are surveyed annually on a rotating‑panel basis. Field enumerators use Computer‑Assisted Personal Interviewing (CAPI) devices to record responses, ensuring real‑time validation and reducing transcription errors. The questionnaire captures detailed activity status, sector of employment, hours worked, and reasons for non‑participation, all coded according to the ILO’s International Standard Classification of Occupations (ISCO‑08).

Key Findings and Trends

The inaugural PLFS release highlighted a women’s labour‑force participation rate (LFPR) of 16.5 % for 2017‑18, which rose to 20.5 % in the 2019‑20 round—a 4‑percentage‑point increase that signalled modest progress in female economic inclusion. Male LFPR remained relatively stable around 55 % during the same period, while the overall unemployment rate (U‑5) edged up from 5.4 % to 5.8 %. The survey also revealed that more than 90 % of employed persons were engaged in the informal sector, underscoring the persistence of precarious work. State‑level tables showed Kerala’s LFPR exceeding 60 % and Bihar’s hovering near 45 %, illustrating stark regional disparities.

Current Implementation and Data Dissemination

As of the 2022‑23 cycle, PLFS continues its quarterly‑urban, annual‑rural cadence, with the NSO publishing detailed tables, analytical briefs and micro‑data files on its official portal (www.mospi.gov.in). The latest release incorporated the 2022‑23 urban quarter, covering 24 800 households and delivering state‑wise unemployment estimates for the first time. Data users can access the micro‑data through a registration‑based download system, enabling custom regressions and longitudinal analyses. The NSO also collaborates with the World Bank and the International Labour Organization to benchmark India’s labour indicators against global trends.

Significance for Policy and Research

PLFS data underpins a range of policy instruments, from the allocation of funds under the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) to the calibration of skill‑development programmes by the Ministry of Skill Development and Entrepreneurship. By providing timely estimates of sector‑wise employment, the survey assists the Reserve Bank of India in assessing labour‑market pressures that influence monetary policy. Academics cite PLFS as the primary source for studies on gender gaps, informal employment, and the impact of COVID‑19 on work patterns, given its high frequency and methodological robustness. Consequently, PLFS has become an indispensable statistical backbone for evidence‑based decision‑making in India’s rapidly evolving economy.
