India’s cities tell two stories at once. One is of gleaming skylines, expanding metro networks, and a booming services economy. The other is of millions of people living in cramped, makeshift settlements without clean water, secure tenure, or reliable sanitation. Urban poverty, housing deprivation, and the proliferation of slums are not fringe issues in India – they sit at the very heart of how rapid urbanization has unfolded in one of the world’s most populous nations. Understanding this reality requires looking at the numbers, the history, and the lived social dynamics that shape slum life every single day.

The scale of the problem

The numbers alone make the case for urgency. According to World Bank data, over 41 percent of India’s urban population lived in slums as of 2022, even with a gradual downward trend since 2000. The 2011 Census recorded approximately 65.5 million slum dwellers across the country, and estimates for 2025 project roughly 14.2 million slum households – a figure reflecting a 2 percent increase from 2011 levels, driven by continued rural-to-urban migration and a persistent housing shortage.

Maharashtra leads with the highest concentration of slum households, followed by Andhra Pradesh, Uttar Pradesh, and West Bengal. PMAY-U 2024 reports a shortfall of 18.78 million housing units in Indian cities, which compels low-income families to settle in whatever informal space is available. Mumbai, for instance, requires approximately one lakh new apartments per year but constructs only around 20,000. The gap between supply and demand is not a policy failure of one government but a structural deficit decades in the making.

Defining slums and urban poverty

A slum is more than a place with poor housing. UN-Habitat defines a slum household as one that lacks one or more of the following: durable housing, sufficient living space, access to safe water at an affordable price, adequate sanitation, and security of tenure. India’s own legal framework, the Slum Areas (Improvement and Clearance) Act, 1956, defines a slum area as a residential zone where buildings are considered unfit for human habitation due to dilapidation, overcrowding, or the absence of essential amenities like light, ventilation, and sanitation.

Urban poverty, however, is broader than slum residence. Sociologically, urban poverty is a multidimensional problem involving not just lack of income but also exclusion from health services, education, housing security, and social recognition. Many of the urban poor live outside formally designated slum zones – in unauthorized colonies, on pavements, or in precarious peri-urban settlements – and are therefore missed by official statistics. Research published in The Lancet points out that more than half of dwellings classified as slum households by UN-Habitat standards in cities like Chennai, Delhi, and Hyderabad fall outside India’s official slum classifications, indicating a serious undercounting of the problem.

Historical context of slum studies in India

India’s engagement with slum research has a long and layered history. Early scholarly attention came from sociologists and urban planners who studied the conditions of the working poor in industrial cities during the colonial and early post-independence period. Foundational works such as A.R. Desai and S.D. Pillai’s Slums and Urbanization (1970) and V.S. D’Souza’s 1979 paper “Socio-cultural Marginality: A Theory of Urban Slums and Poverty in India” laid the groundwork for understanding slums not merely as housing problems but as expressions of structural inequality and social marginalization.

By the 1990s and 2000s, slum research in India had broadened considerably. Studies using census and NSSO data began tracking how slum populations were not just growing but shifting – moving from city centers to urban peripheries where access to services and infrastructure is significantly worse. Between 2002 and 2012, the total number of slums in India actually decreased from 51,688 to 33,510, yet the slum population grew from 42.5 million to 65.5 million. This paradox reflects densification: fewer but larger and more overcrowded settlements. The Government of India’s Committee on Slum Statistics has also acknowledged that official figures likely represent a gross underestimation, as many small settlements below the threshold of 60-70 households are excluded from the count entirely.

Why slums form: the push-pull dynamic

Slums do not emerge by accident. They are the predictable outcome of a specific set of social and economic conditions. Rural distress – agricultural decline, land fragmentation, caste-based exclusion, and lack of rural infrastructure – pushes workers toward cities in search of wage employment. Cities, in turn, pull them in because urban economies, particularly in construction, domestic work, street vending, and manufacturing, require vast amounts of informal labor.

Around 90 percent of construction workers in Indian cities live in slums due to low wages that make formal housing entirely inaccessible. For migrants from states like Bihar, where poverty rates are high, settling in a slum with a monthly rent of around ₹2,000 is far preferable to accumulating debt in rural areas. The proximity of slums to employment hubs is not incidental – it is the primary logic of their location. Rapid migration combined with inadequate urban planning has resulted in a severe shortage of affordable housing, leaving informal settlements as the only realistic option for millions of low-income households.

Caste, class, and settlement patterns

The social composition of Indian slums is not random. Caste and class intersect strongly in determining who ends up in informal settlements. Scheduled Caste and Scheduled Tribe communities, along with religious minorities, are disproportionately represented in slum populations. Research on Mumbai’s slums has highlighted how minority groups such as Muslims can face a twofold marginalization – excluded both by economic precarity and by social prejudice – making their pathways out of poverty considerably narrower. This intersection of identities means that slum residence is not simply a class issue but a social inequality issue involving caste, religion, and migration status simultaneously.

Deprivations faced by the urban poor

Life in an Indian slum involves navigating multiple, compounding deprivations. Access to basic amenities remains a critical gap. 2011 census data shows that 34 percent of slum households lacked latrines on their premises and 43 percent had no source of drinking water within their dwelling. Overcrowding creates severe public health risks, and slum populations are particularly exposed to waterborne diseases, respiratory infections, and child malnutrition.

According to research cited by Wikipedia’s overview of global slums, malnutrition claims an estimated 56,000 children’s lives annually in urban slums in India, with family income, maternal education, and employment status being the key determining factors. Beyond health, slum dwellers also face deep insecurity of tenure. The Housing and Land Rights Network documented that governments demolished over 36,400 homes and displaced more than 200,000 people across India in 2021 alone, with preliminary data for the first half of 2022 showing over 25,800 further demolitions. For slum dwellers, the threat of eviction is a constant undercurrent of daily life.

Employment and the informal economy

The urban poor are not idle. They are, in fact, deeply integrated into the city’s economic machinery – but almost entirely through the informal sector. Street vendors, domestic workers, rag pickers, construction laborers, rickshaw pullers, and home-based artisans form the backbone of urban services that middle-class city life depends upon. Research on Bangalore’s slums found that studying slum dwellers requires moving beyond consumption indicators to understanding their actual economic contribution to the city – their labor, production roles, and role in urban supply chains. Yet this contribution goes largely unacknowledged in planning and policy. Workers in slums rarely have formal contracts, social security, or protection against wage theft.

The social dynamics of slum life

Slums are frequently mischaracterized as socially disorganized or lawless spaces. The sociological reality is more nuanced. Slums represent both deprivation and resilience – sites of exploitation but also of strong community networks, collective action, and survival strategies. Residents develop dense social ties, informal support systems, and community institutions that help them manage the precarity of their daily lives. Neighborhood associations, rotating credit schemes (chit funds), and shared childcare arrangements are common features of slum social organization.

At the same time, internal hierarchies, factional politics, and the presence of local power brokers (often connected to political parties) can reinforce inequalities within slums themselves. Research drawing on Katherine Boo’s detailed account of Mumbai’s Annawadi slum illustrates how corruption can be a structural feature of slum governance – not simply a moral failure of individuals but an outcome of systemic exclusion, where people denied formal institutions must navigate informal power structures to access basic resources.

Policy responses and their limitations

India has had a long history of slum-related policy, ranging from clearance and demolition in the early decades to more recent in-situ upgrading and rehabilitation approaches. The Rajiv Awas Yojana aimed at creating a slum-free India by assigning property rights and upgrading existing settlements. The more recent Pradhan Mantri Awas Yojana – Urban (PMAY-U), launched in 2015, targets urban housing shortage across economically weaker sections, low-income groups, and slum dwellers by providing central assistance for house construction, slum redevelopment, and affordable rental housing. A sub-scheme under PMAY-U – the Affordable Rental Housing Complexes (ARHC) initiative – was specifically designed to provide dignified rental housing to migrant workers and the urban poor close to their workplaces.

Despite these interventions, the housing deficit remains substantial. Only 30 percent of urban land in India is appropriately planned according to the Ministry of Housing and Urban Affairs, and demand for affordable housing continues to far outpace supply. Experts argue that effective solutions require not just construction targets but land tenure security, participatory planning, investment in public services, and recognition of the informal economy’s workers as legitimate urban citizens rather than encroachers to be removed.

Slums as assets, not liabilities

A growing body of sociological and urban planning scholarship argues for reframing how we see slums. Rather than treating them as problems to be erased, this perspective sees them as settlements built by the poor through their own resources and ingenuity – places that deserve upgrading and integration rather than demolition. Dharavi in Mumbai, often cited as Asia’s largest slum, is also a self-contained economic township generating significant economic output, with its own social zones, trade networks, and community institutions. Any redevelopment plan that ignores its socio-cultural fabric is likely to fail or displace its residents without improving their lives.

Urban poverty and slums in India are, at their core, products of structural inequality – of an economic system that draws cheap labor into cities without providing the housing, services, or tenure security those workers need. Addressing them requires going beyond numbers and infrastructure to engage seriously with the social realities of the urban poor: their labor, their rights, their communities, and their agency.

What do you think? If slums are partly a product of the city’s own demand for informal labor, does that mean cities have a responsibility to provide their residents with formal housing and security of tenure? And given the scale of the housing deficit in Indian cities, is incremental upgrading of existing slums a more realistic path forward than large-scale redevelopment projects?
