Revision summary
Hart and the ILO named unregulated, unregistered work as the informal sector. It is a relation to the state and to formal firms, not a separate traditional economy. In India most workers remain informal: vending, construction, home-based and farm labour. Sociological significance lies in livelihood, gender, migration and incomplete citizenship. Critique: growth has not dissolved informality; capital often depends on it. COVID-19 migrants showed the welfare gap inside this structure.
Model answer
Copper italics in this answer — like this — are the key facts. Each one is unpacked in the Facts & figures rail.
Introduction
The informal sector is the large zone of work that is unregistered or weakly regulated, where labour law, tax and social security barely reach. Keith Hart coined the term from urban Ghana; the ILO then made it a development category. In developing societies, including India, it is not a leftover. It is how most people earn, and that fact has sociological, not only economic, significance.
Body
What it is
Informal work includes street vending, home-based piecework, small workshops, domestic service, construction gangs and much of agriculture and allied labour. Alejandro Portes and others stressed that informality is a relation to the state and to formal firms, not a separate “traditional” economy. Formal capital often puts out work to informal units to cut costs. Jan Breman’s fieldwork on circular migrants in western India showed footloose labour moving between farm, brick kiln and city without a stable contract. Women are over-represented in the least visible home-based and care work, as SEWA’s organising and the NCEUS reports documented. PLFS figures still place the vast majority of Indian workers outside secure formal jobs.
Sociological significance and critique
- Significance first: the informal sector absorbs surplus labour, cushions unemployment, and builds urban livelihoods when industry does not create enough formal jobs. It shapes class without looking like a factory proletariat: self-employment can hide disguised wage labour. It structures gender, because unpaid household work and paid informal work blur. It structures the city: slums, street economies and police discretion. It also limits citizenship: no PF, no paid leave, weak unions, high accident risk.
The critical side is that celebrating “entrepreneurship” can romanticise precarity. Dualist models that expect informality to vanish with growth have been disappointed. Global value chains often need the informal tail. During COVID-19 the migrant crisis made the missing welfare architecture visible. Sociologically, the informal sector is therefore the normal form of labour in many developing societies, a site of both survival and exploitation, and a challenge to theories that still take the Fordist worker as the type.

Conclusion
In developing societies the informal sector is the main organisation of work, not an exception. It matters for class, gender, migration and the reach of the state. A critical view refuses both contempt for street livelihoods and the myth that unregulated work is freely chosen enterprise.

Is a small registered shop informal?
Informality is a matter of regulation and security, not only size. Many small units are mixed: partly billed, partly cash.
-
Why is this sociology rather than economics?
Because it reorganises class, gender, the city and citizenship, not only GDP accounting.

Discuss the significance and limitations of 'intersectionality' in social research
Sociology
Intersectionality, coined by Kimberlé Crenshaw, examines how overlapping identities like race, class, and gender shape systemic oppression. Its significance in social research lies in capturing lived realities beyond single-axis frameworks and preventing reductive generalisations. However, limitations include methodological complexity, risks of infinite regress, and difficulties in operationalising fluid categories. Effective application requires balancing structural macro-analysis with micro-level lived experiences.

Discuss the intellectual origins of sociology and its evolution as a distinct field of study
Sociology
Sociology arose in 19th-century Western Europe to make sense of massive upheavals caused by the Industrial and French Revolutions. Enlightenment thinkers laid the groundwork by championing reason, empirical observation, and human agency over traditional dogma. Auguste Comte gave the discipline its name, pushing for a positivist "physics of society" based on scientific laws. Émile Durkheim secured its academic legitimacy by defining "social facts" and using empirical methods to study human behavior. Max Weber introduced interpretive sociology, while Karl Marx focused on material conditions and class struggle. In the 20th century, Talcott Parsons advanced structural-functionalism to study systemic equilibrium. Later, conflict theories, the Frankfurt School, and postmodern critiques broadened the field to address power and marginalisation. Today, sociology continues to evolve by analyzing globalisation, digital shifts, and modern identity politics.
