Breaking down the question
The instruction is to write an analytical note, not a descriptive one. The examiner is signalling that a catalogue of slum conditions — congestion, poor sanitation, insecure tenure — will not suffice. The candidate must explain why slums arise, what they reveal about the pattern of Indian urbanisation, and how sociology reads them.
The phrase in cities locates the answer within urban sociology and the study of industrialisation and urbanisation in India. A strong response treats the slum as a lens on the wider process of urban growth rather than as an isolated problem of housing.
The note on slums and urban deprivation supplies the conceptual grounding for this analysis.
How to approach it
Open by defining a slum sociologically, then move quickly to causation. The analytical core is the argument that Indian slums are the product of over-urbanisation — urban population growing faster than industry can absorb it — rather than of urbanisation as such.
Layer in the informal sector, the failure of planned housing and speculative land markets, and finish by treating slums as functional spaces that reproduce the labour the formal city depends upon. Keep description subordinate to explanation throughout, and close by reframing the slum as a structural feature of India's unbalanced urban growth.
Model answer
A slum is an overcrowded, poorly serviced residential settlement marked by insecure tenure, inadequate sanitation and substandard housing. Sociologically, it is less a place than a relationship — the spatial expression of how a city distributes wealth, work and shelter among its inhabitants.
The causal engine — migration and the labour market. Industrialisation concentrates employment in cities, and the rural push of agrarian distress combines with the urban pull of wages to drive migration. Migrants unable to afford formal housing settle in slums close to their work. The slum is thus the visible residue of a labour market that draws people into the city faster than it can house them.
The Indian specificity — over-urbanisation. In the classical Western path, industry absorbed migrants into factory employment and an expanding formal housing stock. India instead exhibits over-urbanisation: the urban population has grown faster than industrial jobs can absorb. The consequence is a swollen informal sector — Jan Breman's footloose labour of casual, low-paid work — that cannot fund adequate shelter. The slum therefore expresses the shortfall of industrialisation as much as its presence.
Planning and land-market failure. Speculative land prices, inadequate public housing and weak urban governance push even the regularly employed into informal settlements. Here the slum manifests a governance deficit rather than urbanisation itself, which is why the poor are so often criminalised as encroachers rather than recognised as workers the city needs.
The slum as a functional space. Louis Wirth's urbanism portrayed the city as impersonal and anomic, yet Indian slum studies reveal dense networks of kinship, caste and reciprocity. Slums are not mere pathology: they house the labour that services the formal city and sustain thick livelihood networks. This is why demolition without rehabilitation simply reproduces slums elsewhere.
Analytically, then, the slum is not an accident of city life but a structural feature of India's over-urbanised, informalised growth — a settlement form produced by the gap between the city's demand for labour and its provision of shelter.
Examiner's perspective
Weak answers read analytical note as licence for a list — describing filth, disease and crime without explaining causation. The examiner is testing whether the candidate can move from description to structural analysis, distinguishing urbanisation as a general process from India's over-urbanised pattern.
High marks reward the deployment of over-urbanisation, the informal sector and planning failure, together with a conclusion that reframes slums as functional spaces rather than pure pathology. Citing Breman, Wirth or M. S. A. Rao signals command of urban sociology and lifts the answer above a current-affairs treatment of the theme.
