The informal sector refers to economic activity that lies outside the reach of state registration, labour law and social protection — petty production, street trade, domestic service, construction gangs, home-based piecework, small workshops and the great mass of own-account work. The term is best understood not as a separate economy but as a form of employment relation: work that is casual, unwritten, unenumerated and unprotected. Indian usage therefore prefers the broader idea of informal employment, which includes unprotected workers found inside registered firms as well as those in unregistered enterprises.
The concept entered social science through the anthropologist Keith Hart (1973), who observed in Accra that the urban poor were not unemployed but intensely busy in a dense field of income opportunities invisible to official statistics. The International Labour Organization's Kenya mission report (1972) turned the observation into a policy category. Both broke with the dualist expectation that industrialisation would steadily absorb such workers into a modern wage economy.
Defining characteristics and scale
Indian scholarship, consolidated by the National Commission for Enterprises in the Unorganised Sector (NCEUS, 2007), identifies a cluster of features rather than a single criterion: enterprises are unregistered and typically employ only a handful of workers; capital per worker is low and technology simple; the employment relation rests on oral agreement, kinship or contractor networks; earnings are irregular and often below statutory minima; and there is no social security — no provident fund, pension, paid leave or enforceable protection against dismissal or injury. Two employment statuses dominate: casual wage labour, hired by the day or the task, and self-employment, which in India covers a very large share of the workforce and ranges from petty traders to distress-driven own-account producers.
The Indian magnitude
Successive official surveys agree that the overwhelming majority of Indian workers — on most measures well over four-fifths — are informally employed, and that the organised sector's share of total employment has grown only marginally across decades of rapid output growth. This is the central puzzle of Indian labour sociology: jobless growth, or more precisely growth that expands output and profits without expanding protected employment. The pattern is gendered and caste-marked. Women are concentrated in home-based and domestic work; Dalit and Adivasi workers are over-represented in the most casualised occupations, so that social identity and labour status reinforce one another.
Informality inside the formal sector
The sharpest recent shift is the growth of informality within registered firms through contractualisation. Principal employers increasingly hire through labour contractors, apprentices, trainees and fixed-term arrangements, so that workers on the same shop floor, doing the same task, hold radically different entitlements. Barbara Harriss-White describes the resulting order as an economy regulated less by law than by caste, kinship, gender and locality — an informal economy of regulation in which social institutions do the work that contracts and inspectors are supposed to do.
Breman: footloose labour and neo-bondage
Jan Breman's long fieldwork in south Gujarat gave the field its most influential vocabulary. His footloose labour describes a huge reserve of workers detached from land yet never absorbed into settled industrial employment, endlessly mobile between village and worksite. Such circular migration — to brick kilns, cane fields, quarries and construction sites for the dry season, back to the village in the monsoon — keeps workers legally invisible and politically unorganisable, because they belong fully to neither place. Breman also demonstrated the persistence of neo-bondage: advance payments given by contractors before departure bind the migrant not to a hereditary master but to a succession of employers through debt. Unlike older attachment, this is contractual, temporary and stripped of patronage obligation — bondage without even the protection paternalism once offered. Such work reproduces alienation in acute form, since the worker owns neither product, process nor place.
Why informality persists
Three explanations compete. Legalist accounts blame over-regulation, arguing that firms stay small and unregistered to evade labour law. Structuralist accounts, dominant in India, argue instead that informality is functional for capital: subcontracting transfers risk and cost downward, and a vast labour reserve holds wages near subsistence. Kalyan Sanyal offers a third reading — a need economy that capital neither absorbs nor destroys, and which the state manages through welfare rather than employment. All three agree that informality is a structural feature of Indian capitalism, not a transitional stage.
Policy responses and their limits
Responses have moved from enterprise promotion to welfare-based inclusion: tripartite welfare boards, the Unorganised Workers' Social Security Act (2008), the employment guarantee as a rural wage floor, and portable insurance and pension schemes. Their reach is limited by registration burdens, employer non-compliance and the sheer difficulty of identifying an employer for a footloose worker. The Self Employed Women's Association's model of organising the unorganised suggests that recognition and collective voice matter as much as benefit design.
For the UPSC answer
Define informality as a quality of the employment relation, not a marginal enclave, and cite Hart and the ILO for origin, NCEUS for the Indian definition. Use Breman's footloose labour, circular migration and neo-bondage as your primary evidence, and Harriss-White for the caste-gender regulation of markets — this is where most answers stay vague. Always make the counter-intuitive point that informality has grown with liberalisation through contractualisation, which lets you connect this topic to jobless growth, rural labour and urban deprivation. Close by evaluating welfare-based responses rather than merely listing schemes.
