Informal Labour and the Structure of the Indian Economy

A defining structural feature of the Indian economy is that the overwhelming majority of its workforce, by most estimates over 80-90 percent, is employed in the informal sector: without written contracts, social security, or reliable legal protection. This includes street vendors, domestic workers, construction labourers, home-based piece-rate workers, and small unregistered enterprises. Understanding this reality requires moving beyond formal labour law, designed largely around factory employment, to grapple with a vastly more heterogeneous and precarious set of livelihoods that nonetheless generate a substantial share of national output.

The Periodic Labour Force Survey (PLFS), which replaced the older National Sample Survey Organisation (NSSO) employment-unemployment rounds, attempts to capture this complexity through categories such as usual status, current weekly status, and current daily status employment, each yielding different unemployment estimates depending on the reference period used. This methodological plurality reflects genuine difficulty in defining 'employment' for populations that combine seasonal agricultural labour, informal urban work, and periods of open unemployment within a single year, sometimes within a single household.

Internal migration is central to how informal labour markets function. Seasonal and circular migration corridors, such as those linking rural Bihar and eastern Uttar Pradesh to Delhi, Mumbai, and Punjab's agricultural belt, or Odisha's tribal districts to brick kilns in southern states, move tens of millions of workers annually in patterns largely invisible to residence-based census counts. The COVID-19 lockdown of 2020 dramatically exposed the scale and vulnerability of this migrant workforce when transportation shutdowns stranded millions of workers far from home without income or food security, prompting a wave of scholarly and journalistic attention to labour informality that had previously received comparatively little policy focus.

Feminist labour economists have highlighted that women's informal work, especially unpaid domestic labour and home-based production, is systematically undercounted in standard labour force statistics, which tend to use definitions of 'work' calibrated to male, market-oriented employment patterns. Time-use surveys conducted by the NSSO have attempted to correct this by measuring all productive activity including unpaid care work, revealing that Indian women perform a dramatically larger share of unpaid domestic and care labour than men across all income and education levels.

Debates over how to formalize India's informal economy — through labour codes, digital payment mandates, or social security extension schemes like e-Shram registration — illustrate a persistent tension between protecting workers and preserving the flexibility that makes informal employment viable for both employers and workers who value its low entry barriers. Reading labour statistics as historically and politically constructed documents, rather than neutral counts, is essential to understanding why informality remains simultaneously a site of exploitation and a crucial safety valve for surplus agrarian labour.
