Settlements and Urbanization in India

Rural Settlement Types and Distribution

A settlement is any form of human habitation, from a single dwelling to a large city. Rural settlements are those in which the majority of the population is engaged in primary economic activities (agriculture, fishing, forestry, mining) and which fall below the urban threshold in terms of population size and density. The Census of India defines a rural settlement (village) as a place with a population below 5,000, a density below 400 persons per square kilometre, and where at least 75 percent of the male working population is engaged in agriculture. Any place not fulfilling these criteria, or which has been declared a town by the local government, is classified as urban. India in 2011 had 640,867 inhabited villages, containing 833 million people or 68.8 percent of the total population, making rural settlement geography central to understanding India's social and spatial organisation.

Rural settlements are classified on the basis of their form or shape, their size, their site and situation, and the social basis of their origin. Based on form, four main types are recognised. Compact or nucleated settlements are those in which houses are clustered closely together into a central mass with fields surrounding the village. This is the most common pattern in the fertile Indo-Gangetic Plain, the Deccan Plateau, and the coastal plains where agricultural land is productive enough to support dense rural populations. The nucleated pattern is associated with cooperative labour requirements (irrigation management, defence), social cohesion of caste-based village communities, shared access to water sources (wells, tanks, ponds), and the need for security in historically insecure areas. Semi-compact settlements occur where the core is nucleated but subsidiary hamlets (paras or padas) exist at some distance from the core, often occupied by specific caste or occupational groups spatially segregated from the main settlement. This is very common in central and peninsular India.

Dispersed or hamleted settlements consist of single farmsteads or small clusters widely scattered across the landscape, with no common village core. This pattern dominates in hilly and forested areas of the Himalayan foothills, the Western Ghats, and the Chotanagpur Plateau, where broken terrain limits agglomeration, and in the Terai belt where recent agricultural colonisation has produced dispersed farmstead patterns. Dispersed settlements reflect lower population density, individual tenure of forest or upland land, and the physical barriers of hills and valleys that limit the centralisation typical of plains villages. In the northeastern states, tribal settlements are often dispersed across forest clearings, reflecting the jhum (shifting cultivation) system that requires periodic movement of cultivated plots. Linear settlements develop along roads, railway lines, river banks, or coastal strips where linear features provide access and amenity. The ribbon development along National Highways and State Highways is increasingly prominent around expanding urban areas and is a characteristic feature of the urban-rural fringe in contemporary India.

The factors determining settlement form include physical geography (relief controls whether nucleation is feasible; rivers provide water but also flood risk determining whether settlements are on terraces or elevated sites; soil type and depth influence agricultural productivity and thus settlement density); social and cultural factors (caste-based spatial segregation produces the characteristic pattern of lower-caste hamlets at the edge of the main village; joint family systems encourage nucleated forms; tribal communities often have distinctive longhouse or clan-based settlement forms); historical factors (defensive needs produced nucleated hilltop settlements in Rajasthan and medieval forts, while secure plains allowed dispersal; colonial land revenue systems created or reinforced nucleated revenue villages as units of administration); and economic factors (availability of water, proximity to markets and roads, and the nature of the agricultural system - plantation agriculture produces dispersed estate workers' quarters, while paddy cultivation in flooded plains produces nucleated villages on slightly elevated sites).

Settlement site and situation are geographical concepts distinguishing the specific physical location of a settlement (the site - hilltop, river confluence, spring line, south-facing slope, gap in ridge) from its broader regional position relative to surrounding areas (the situation - on a trade route, at a ford, between two ecological zones). Classical site factors include: proximity to water (most Indian villages are located near a perennial water source - well, tank, river, spring); defensive advantage (hilltop, moat, meander neck); flat, well-drained land for housing; south-facing slopes in the Himalayas for solar exposure; and gap or pass locations for route-focused settlements. The gap towns of the Himalayan foothills (Jammu, Pathankot, Ambala, Haridwar, Siliguri) developed where passes through the Siwalik Hills channelled trade and movement.

Rural settlement distribution in India reflects the underlying agricultural geography. The highest rural population densities are in the Ganga-Yamuna Doab, the Bengal delta, the coastal deltas of the Krishna, Godavari, Kaveri, and Mahanadi rivers, and the Malabar coast of Kerala, all areas of fertile soils, reliable water supply, and intensive rice or wheat cultivation. Villages in these areas may have populations of several thousand and be only a few kilometres apart. In contrast, the Thar Desert, the Rann of Kutch, the Himalayan high-altitude zones, and the forested tribal belt of central India have very sparse village distribution with long distances between settlements and small population sizes. The average village population in India is approximately 1,300 (2011 Census), but this conceals enormous variation from single-household hamlets to densely inhabited villages of 20,000 or more in the Gangetic Plain.

Rural settlement problems in India include inadequate drinking water supply (despite major programmes like Jal Jeevan Mission which aims to provide tap water to all rural households by 2024, many villages depend on hand pumps, open wells, and seasonal ponds contaminated by agricultural runoff and open defecation); poor sanitation and the legacy of open defecation (the Swachh Bharat Mission Gramin targeted achieving open defecation free status by 2019 and claimed this target was reached, though independent surveys suggested incomplete coverage); poor connectivity (many villages lack all-weather roads; the Pradhan Mantri Gram Sadak Yojana or PMGSY has aimed to connect all habitations above 500 population with all-weather roads); electricity access (Saubhagya scheme aimed for universal household electrification by 2018); digital connectivity gaps; inadequate rural healthcare (sub-centres, Primary Health Centres, and Community Health Centres below required norms of staffing and infrastructure in many states); and the shrinkage and degradation of common land resources (grazing commons, water bodies, and forests) through encroachment and conversion to private agricultural use.

Urban Growth in India

Urban areas in India are classified into two categories by the Census. Statutory towns are places that have been constituted as municipalities, cantonment boards, or notified area committees by law, regardless of population size or demographic characteristics. Census towns are places that satisfy the demographic criteria (population above 5,000, density above 400 persons per square kilometre, and at least 75 percent of male working population in non-agricultural activities) but have not been declared urban by the local government; they are technically governed as rural areas but have an urban character. The dramatic increase in census towns from 1,362 in 2001 to 3,894 in 2011 reflects both real urbanisation and a reclassification of previously counted rural areas that had become urbanised in character.

India's urban population grew from 17.3 percent in 1951 to 31.2 percent in 2011 (377.1 million), an increase of approximately 91 million people in the 2001-11 decade alone. Projections suggest India's urban population will reach 40 to 50 percent of total population by 2030 to 2040, implying the addition of 200 to 300 million more urban residents. India had 7,933 towns in 2011, of which 4,041 were statutory and 3,892 were census towns. The number and size of cities has grown dramatically: the number of million-plus cities grew from 5 in 1971 to 35 in 2011, and India has 5 megacities with population above 10 million.

The historical pattern of urban growth in India reflects colonial economic geography. The three Presidency towns of Bombay (now Mumbai), Calcutta (Kolkata), and Madras (Chennai) were the primary nodes of colonial commerce, administration, and trade, connected to ports and railways that extracted raw materials and distributed manufactured goods. These cities grew rapidly under colonialism and retained their primacy after Independence. Inland cities like Delhi, Hyderabad, and Bangalore grew more slowly under colonialism but have become major metropolitan centres since Independence as industrialisation, government investment, and IT industry concentration have driven growth in the interior.

The factors driving contemporary urbanisation in India include: rural push (agricultural underemployment, land fragmentation, drought, caste discrimination, and limited rural non-farm opportunities push labour to cities); urban pull (higher wages, better employment opportunities in construction, manufacturing, and services, access to education and health facilities, social freedom from village hierarchies); natural increase (the urban population grows through its own birth rate, which though lower than rural areas still adds significantly to urban numbers); reclassification of rural to urban (as villages grow and industrialise, they are reclassified as urban areas, adding to urban population counts without actual migration); and government policy (location of public sector industries, educational institutions, administrative functions, and infrastructure in cities creates employment that attracts migrants).

Urban centres in India are classified by the Census into six size classes based on population: Class I (100,000 and above); Class II (50,000 to 99,999); Class III (20,000 to 49,999); Class IV (10,000 to 19,999); Class V (5,000 to 9,999); and Class VI (below 5,000). Class I cities account for approximately 70 percent of India's urban population despite being only a small fraction of urban settlements, reflecting the primate city pattern of Indian urbanisation where a few very large cities concentrate most urban economic activity, employment, and population.

Problems of Urbanisation

India's rapid urbanisation has been characterised as urbanisation without adequate urban development, meaning that cities have grown faster than the infrastructure, services, and institutions required to support their populations. The result is a set of interconnected urban crises that undermine quality of life, economic productivity, and environmental sustainability.

Urban housing shortage is acute: the urban housing shortage in India was estimated at 18.78 million units in 2012 by the High Level Task Force on Affordable Housing, and this shortage falls disproportionately on economically weaker sections and low-income groups. Land prices in major cities have been driven to extraordinary levels by speculation, constrained supply (Floor Space Index or FAR regulations, outdated urban land ceiling acts that have reduced the supply of developable land), and poor urban planning. The result is that the urban poor are priced out of formal housing markets and resort to slums, unauthorised colonies, and pavement dwelling. The Pradhan Mantri Awas Yojana (Urban), launched in 2015 with the target of Housing for All by 2022, aimed to construct 11.2 million affordable houses for urban poor but implementation has been significantly behind target.

Urban water supply and sanitation are severely deficient. Most Indian cities supply water for only a few hours per day, forcing households to store water in tanks and increasing the risk of contamination. Non-Revenue Water (water lost through leakage, theft, and unbilled consumption) is estimated at 35 to 50 percent of total water supplied in most Indian cities, representing an enormous resource loss. Urban groundwater tables are falling rapidly in cities like Chennai, Bengaluru, Delhi, and Hyderabad as groundwater extraction far exceeds recharge. Chennai faced a severe water crisis in 2019 when all four major reservoirs ran dry simultaneously, requiring emergency water supply by trains. Urban sanitation coverage has improved but remains incomplete: only about 65 to 70 percent of urban households had access to piped sewerage as of 2021, and sewage treatment capacity covers only a fraction of the sewage generated. Untreated urban sewage is the primary cause of contamination of rivers flowing through cities, with the Ganga, Yamuna, and Cooum rivers receiving billions of litres of untreated sewage daily.

Urban transport and congestion are among the most visible urban problems. India's cities were not planned for the volumes of motor vehicles now using them: Delhi has over 13 million registered vehicles, Mumbai over 4 million, Bengaluru over 8 million. Road space is inadequate, traffic signals are poorly coordinated, encroachment reduces effective road width, and the share of road space allocated to pedestrians and cyclists (who form the majority of urban travellers) is minimal. The result is chronic congestion that imposes enormous economic costs (lost working hours, fuel wastage, increased accident risk). Air pollution from vehicle exhaust is a major public health crisis in Delhi and other cities: Delhi's PM2.5 concentrations regularly exceed WHO guidelines by 10 to 20 times during winter months when temperature inversions trap pollutants. Public transport systems in most Indian cities are inadequate relative to demand, forcing over-reliance on private vehicles and two-wheelers. Metro rail systems are operational in Delhi (the largest at 391 km), Mumbai, Bengaluru, Hyderabad, Chennai, Kolkata, Kochi, Pune, Ahmedabad, Jaipur, Nagpur, and Lucknow, but cover only a fraction of trip demand. The AMRUT (Atal Mission for Rejuvenation and Urban Transformation) programme aims to improve urban infrastructure including water, sewerage, stormwater drainage, urban transport, and green spaces in 500 cities.

Urban solid waste management is in crisis: India's cities generate approximately 150,000 tonnes of municipal solid waste per day, of which only 20 to 30 percent is scientifically processed or treated. The rest is disposed of in open dumpsites and landfills that pollute groundwater, generate methane (a potent greenhouse gas), and create health and fire hazards. The Swachh Bharat Mission Urban targeted 100 percent door-to-door waste collection, segregation at source, and scientific disposal, with significant but incomplete progress. Urban flooding is increasingly severe as cities expand onto floodplains and low-lying areas, wetlands are drained for construction, storm drains are encroached upon, and impervious surface cover prevents rainwater infiltration. The Mumbai floods of 2005 (944 mm rain in 24 hours killing over 1,000 people), the Chennai floods of 2015, and annual flooding of Bengaluru streets have highlighted the vulnerability of poorly planned urban development to intense rainfall events that will become more frequent under climate change.

Urban poverty and inequality, discussed in detail in the slums section below, represent perhaps the most fundamental urban challenge. The concentration of economic opportunity in cities draws the rural poor, but the absence of affordable housing, formal employment, and social protection systems means that a large fraction of the urban population lives in precarious conditions. Urban heat island effect (cities are significantly warmer than surrounding rural areas due to high absorption surfaces, waste heat from vehicles and air conditioners, and reduced vegetation) increases energy demand and creates health risks particularly for outdoor workers and the elderly poor.

Million Cities and Metropolitan Regions

The 2011 Census identified 53 urban agglomerations with a population of one million or above, collectively known as million-plus cities, and 3 urban agglomerations with population above 10 million (megacities). These cities and urban agglomerations contain a disproportionate share of India's urban population, economic output, and infrastructure investment, but also concentrate urban problems of congestion, pollution, inequality, and governance complexity.

Mumbai Urban Agglomeration is India's largest urban area with a population of 18.4 million in 2011, making it one of the largest in the world. Mumbai is India's financial capital, headquarters of the Reserve Bank of India and most major commercial banks and stock exchanges (BSE and NSE), the home of Bollywood, and the largest port. The city occupies a narrow peninsula extending into the Arabian Sea, severely limiting geographical expansion. This constrained geography combined with massive in-migration has produced a city of extraordinary density and stark spatial inequality. Dharavi, located in the heart of Mumbai between the two suburban railway lines, is often described as Asia's largest slum with a population estimated at 650,000 to 1 million in approximately 2.4 square kilometres. It is also a thriving informal economy hub with leather goods, pottery, textile recycling, and food processing industries generating annual revenues estimated at 650 million dollars. The Dharavi Redevelopment Project, planned since 2004, was relaunched in 2022 with Adani Group as the lead developer, promising to rehouse slum residents in free permanent tenements in exchange for the right to develop the commercially valuable land. The Mumbai Metropolitan Region Development Authority (MMRDA) governs the extended urban region.

Delhi Urban Agglomeration with 16.3 million in 2011 (the National Capital Region or NCR extending to include Gurugram, Faridabad, Noida, Ghaziabad is closer to 30 million) is India's second largest urban area and the national capital. Delhi's economy is dominated by government employment, trade, and services, with a large manufacturing base for consumer goods in the surrounding NCR towns. Delhi has India's most extensive metro rail network, the Delhi Metro Rail Corporation (DMRC), but also India's worst air pollution among major cities due to the combination of vehicle emissions, industrial emissions, agricultural stubble burning in Punjab and Haryana, dust from construction and road surfaces, and winter temperature inversions that trap pollutants. The National Capital Region Planning Board coordinates planning across the NCR's multiple state jurisdictions. Kolkata Urban Agglomeration had 14.1 million in 2011, having grown more slowly than Mumbai and Delhi due to deindustrialisation of its traditional jute, engineering, and chemical industries, slow economic growth of West Bengal relative to other major states, and net out-migration of its middle class to other cities. Kolkata remains an important cultural, educational, and commercial centre but has lost its colonial-era economic primacy.

Bengaluru (Bangalore) Urban Agglomeration grew from 2.9 million in 1991 to 8.4 million in 2011 and is estimated at 13 to 14 million in 2024, making it among the fastest growing major cities in India. Bengaluru's growth has been driven almost entirely by the IT and IT-enabled services (ITES) industry, which clustered in Bengaluru from the 1990s due to the presence of engineering colleges producing graduates, low land costs initially, good climate, existing electronics industry (HAL, BEL, BHEL) and the initial investment by Texas Instruments (1985) and Infosys and Wipro (established locally in the 1980s). The Electronic City and Whitefield IT corridors, along with the ITPL (International Tech Park Limited), are among the most important concentrations of software employment in Asia. Bengaluru's rapid growth has produced severe infrastructure deficits: road congestion, flooding (the city received devastating floods in September 2022 when 130 mm of rain in a day inundated the IT corridors), water scarcity (dependent on Kaveri river water and groundwater), and governance fragmentation across BBMP, BDA, CMC, and industrial townships.

Chennai Urban Agglomeration (7.1 million in 2011) is the gateway to South India, the fourth largest port, and the headquarters of India's automotive industry (often called the Detroit of India), with Hyundai, Ford (now closed), BMW, Renault-Nissan, and a large cluster of automotive component manufacturers concentrated in the Chennai-Sriperumbudur-Kancheepuram corridor. Hyderabad Urban Agglomeration (7.7 million in 2011), despite the bifurcation of Andhra Pradesh creating the new state of Telangana with Hyderabad as its capital (and as the joint capital of both states for ten years), has continued to grow rapidly as a centre for information technology (HITEC City, Cyberabad), pharmaceuticals (India's largest pharmaceutical cluster), and biotechnology. Ahmedabad-Gandhinagar is the primary urban agglomeration of Gujarat, the most industrialised large state, with strong textile, chemical, and pharmaceutical industries, and Gandhinagar as the planned state capital designed in the 1960s. Pune has grown rapidly as a centre for automotive manufacturing (Tata Motors, Bajaj Auto, Mercedes-Benz, Volkswagen, Force Motors), IT services, and education, and is part of the extended Mumbai metropolitan economy.

Primate city phenomenon: India's urban hierarchy is characterised by urban primacy at the state level - each state has one dominant city that is far larger than the second city. Mumbai is roughly 4 times the size of Pune; Kolkata is roughly 5 times the size of Asansol; Chennai is roughly 4 times the size of Coimbatore. This reflects the concentration of investment, government functions, and economic opportunity in the colonial port cities and post-Independence state capitals, which continue to attract disproportionate migration and investment. The rank-size rule (which predicts a smooth logarithmic decline in city sizes from the largest to the smallest) is not well-followed in India, reflecting the primate city pattern. Walter Christaller's Central Place Theory predicts a hierarchical distribution of settlements serving market areas, and while the Indian urban hierarchy broadly conforms to a central place logic, the distortions of colonial geography and post-colonial industrial location policy create significant departures from the ideal pattern.

Urban agglomeration governance in India is complicated by the fact that cities have expanded far beyond their original municipal boundaries, creating continuous built-up areas administered by multiple local bodies (municipal corporations, municipalities, cantonment boards, industrial townships, and census towns). The Metropolitan Planning Committees mandated by the 74th Constitutional Amendment for cities above 1 million population are yet to be constituted in most states, leaving metropolitan governance fragmented. The Jawaharlal Nehru National Urban Renewal Mission (JNNURM, 2005-2014) was India's first large-scale urban investment programme, directing approximately 1.2 lakh crore rupees to infrastructure and governance reforms in 65 selected cities, but was criticised for poor implementation, inadequate attention to governance reforms, and failure to address the needs of the urban poor adequately.

Smart Cities Mission

The Smart Cities Mission (SCM) was launched by the Government of India in June 2015 under the Ministry of Housing and Urban Affairs with the objective of developing 100 cities into smart cities providing core infrastructure, a clean and sustainable environment, and a good quality of life to citizens through the application of smart solutions and information and communication technology. The total proposed investment under SCM is approximately 2.05 lakh crore rupees (approximately 2.05 billion per city over 5 years), with funding shared between the central government, state governments, and urban local bodies, and the expectation that private sector investment would be attracted through the improved investment climate.

Cities were selected through a competitive challenge process conducted in four rounds between 2016 and 2018, in which cities competed by proposing city development plans evaluated on the quality and feasibility of their smart city proposals. The 100 selected cities span all states and union territories. The governance mechanism for Smart Cities Mission is a Special Purpose Vehicle (SPV), a limited company incorporated under the Companies Act at the city level with the municipal body and state government as shareholders, to plan, appraise, approve, release funds, implement, manage, operate, and monitor smart city development projects. This SPV model has been controversial because it creates a parallel governance structure outside the elected municipal body, potentially weakening democratic accountability.

Smart cities projects are of two types. Area-Based Development (ABD) focuses on transforming existing areas through retrofitting (improving existing built-up areas to make them more efficient and liveable), redevelopment (demolishing existing built environment and re-imaging on a blank slate with enhanced infrastructure), and greenfield development (developing new areas on the urban periphery with complete infrastructure and smart technology from scratch). Pan-City Solutions apply smart technology to the entire city, such as intelligent traffic management systems, integrated command and control centres (ICCCs) that monitor city functions including traffic, utilities, surveillance, and emergency response through a single dashboard, smart water and electricity metering, and e-governance platforms for citizen services.

The Integrated Command and Control Centres (ICCCs) developed under SCM represent India's first systematic attempt to use real-time data integration and analytics for urban management. By 2022, approximately 80 cities had established ICCCs, which proved their value during COVID-19 when they were repurposed for pandemic monitoring, tracking quarantine compliance, coordinating healthcare logistics, and disseminating public health information. Cities like Surat, Vadodara, Pune, and Ahmedabad were praised for leveraging their ICCCs during the pandemic.

Assessment of the Smart Cities Mission reveals significant implementation gaps. As of 2023, approximately 50 to 60 percent of the total targeted investment had been completed, with significant variation between cities. The mission has been extended multiple times beyond its original 2020 deadline, most recently to June 2024. Critics have argued that the focus on technology and infrastructure in selected areas (ABD zones typically covering only 0.5 to 5 percent of the city area) creates islands of smart development surrounded by neglected urban areas, exacerbating spatial inequality. The SPV governance model has been criticised for bypassing elected municipal councils. Outcome measurement, focused on projects completed and funds spent rather than improvements in citizen quality of life, has also been questioned. Nevertheless, the mission has catalysed urban data collection, introduced smart technology in many cities that had no prior digital infrastructure, and focused national attention and resources on urban development in a way that had been absent before.

Complementary urban missions include AMRUT (Atal Mission for Rejuvenation and Urban Transformation), covering 500 cities with population above 100,000 for basic infrastructure (water supply, sewerage, urban transport, parks, and stormwater drainage); PMAY-Urban (Pradhan Mantri Awas Yojana Urban) for affordable housing; National Urban Livelihoods Mission (NULM) for urban poor economic integration; Heritage City Development and Augmentation Yojana (HRIDAY) for conserving and revitalising cultural heritage in 12 heritage cities (Amritsar, Ajmer, Dwarka, Gaya, Mathura, Varanasi, Kanchipuram, Vellankanni, Badami, Puri, Amaravati, Warangal); and the Digital India Land Records Modernisation Programme to create digital urban land records.

Urban Poverty and Slums

Urban poverty in India is both extensive and qualitatively different from rural poverty. The urban poor face a distinct set of vulnerabilities: insecure tenure (living in slums or on pavements without legal title to their dwelling, subject to eviction by the state or landlords); higher cost of living (urban food, fuel, water, and rent prices are higher than rural areas, meaning the same nominal income buys less welfare); informal employment with no social security (no pension, healthcare, maternity benefits, or job security); exposure to multiple environmental hazards (air pollution, waterborne disease, fire risk in densely packed slum areas); and social marginalisation. The Tendulkar Committee poverty line for urban areas (used for the 2011-12 poverty estimates) was set at a monthly per capita expenditure of Rs 1,000 in urban areas, below which approximately 13.7 percent of India's urban population lived in 2011-12 according to official estimates, though independent researchers and the Rangarajan Committee (2014) suggested higher poverty incidence using a higher poverty line calibrated to nutritional and other needs.

Slums are defined under the Slum Areas (Improvement and Clearance) Act 1956 as areas where buildings are used as dwellings, are unfit for human habitation, are in an advanced state of dilapidation, and lack adequate drainage, sanitation, water supply, or are overcrowded. The Census of India (2011) identified slum households in 2,613 cities and towns and recorded 13.7 million slum households containing approximately 65.5 million slum dwellers, constituting 17.4 percent of India's urban population. This number is widely considered an undercount as it uses statutory notification by state governments as one criterion for slum identification, and many unnotified slums are excluded.

The spatial distribution of slums reflects the geography of urban economic opportunities and land prices. The largest absolute numbers of slum dwellers are in Maharashtra (11.1 million), Andhra Pradesh (5.5 million), and West Bengal (4.1 million). As a proportion of urban population, states with rapidly growing industrial cities (Chhattisgarh, Odisha, Maharashtra, Andhra Pradesh) have higher slum percentages. Mumbai's slum population is estimated at 40 to 55 percent of the total urban population despite strict laws restricting new slum formation, reflecting the failure of formal housing markets to provide affordable alternatives. Delhi's jhuggi-jhopri (JJ) clusters house approximately 2 to 4 million people across hundreds of informal settlements. Bengaluru's slum population is concentrated in the older industrial areas and along the periphery where migrant construction workers settle.

The characteristics of Indian slums include severe overcrowding (average floor area of 10 to 20 square metres per household), inadequate water supply (dependence on shared standposts or water vendors who charge 5 to 10 times the piped water tariff), poor sanitation (shared community toilets or open defecation due to the lack of private toilet facilities), high susceptibility to flooding (slums are frequently located on low-lying areas, floodplains, and along drains that are the only land available to the poor), fire risk (dense combustible construction of tin, plastic, and wood), poor electricity supply (illegal connections or absence of electricity), and lack of solid waste collection. Health outcomes in slums are significantly worse than in formal urban areas: tuberculosis incidence is 5 to 10 times higher, diarrhoeal disease mortality higher, and malnutrition comparable to or worse than rural poor.

The social and economic composition of slums reflects the sources of urban in-migration: the majority of slum dwellers are recent migrants from rural areas or from smaller towns, belonging disproportionately to SC, ST, and OBC communities, and employed in construction, domestic service, street vending, rag-picking, loading and unloading, and other informal occupations. However, older established slums like Dharavi contain generations of urban-born residents who have developed complex social networks, small-scale enterprises, and local political organisations. The livelihoods generated within slums are often sophisticated: Dharavi's pottery colony (Kumbharwada), leather goods workshops, textile recycling, and food processing industries collectively generate annual revenues in the hundreds of millions of dollars, providing livelihoods not just to residents but to the broader urban economy.

Slum upgrading versus slum clearance has been a contested policy question in India since Independence. The clearance approach, dominant in the 1950s and 1960s, demolished slums and relocated residents to distant peripheral sites, typically on the theory that slums were a temporary pathology to be eradicated. The relocation approach consistently failed: relocated residents, cut off from their employment centres and social networks, often abandoned the distant sites and rebuilt slums closer to the city centre. From the 1970s onward, international best practice and Indian policy increasingly shifted toward in-situ upgrading: providing secure tenure, water, sanitation, drainage, and electricity to existing slum residents where they are, rather than relocating them. The Rajiv Awas Yojana (RAY, 2011) was designed around a slum-free city planning approach that combined in-situ upgrading of existing slums with provision of affordable housing for new urban poor arrivals. It was replaced by PMAY-Urban (2015) which provides a central subsidy for construction or improvement of houses for the urban poor through four verticals: in-situ slum rehabilitation on private land, credit-linked subsidy for home loans, affordable housing in partnership with developers, and beneficiary-led individual housing construction.

Street vendors constitute approximately 10 million people across India's urban areas and provide an essential, affordable retail and food service function for both the urban poor as consumers and as a livelihood for the vendors themselves. They have historically been subject to arbitrary eviction by municipal authorities and harassment by police. The Street Vendors (Protection of Livelihood and Regulation of Street Vending) Act 2014 provided a statutory framework for the first time, requiring cities to conduct surveys of existing vendors, issue identity cards, designate vending zones, and constitute Town Vending Committees with vendor representation for self-governance. Implementation has been variable but the Act represents an important recognition of the informal urban economy as a legitimate economic activity deserving protection rather than suppression.

Urban livelihoods programmes have tried to address the employment dimension of urban poverty. The Deendayal Antyodaya Yojana - National Urban Livelihoods Mission (DAY-NULM), formerly the SJSRY (Swarna Jayanti Shahari Rozgar Yojana), aims to reduce poverty and vulnerability of the urban poor by enabling access to gainful self-employment and skilled wage employment, social mobilisation through Self Help Groups (SHGs), and shelters for the urban homeless. The Prime Minister's Employment Generation Programme (PMEGP) provides credit-linked subsidies for setting up micro-enterprises in both urban and rural areas. The PM Vishwakarma scheme launched in 2023 specifically targets traditional artisans and craftsmen, providing skill training, credit access, and market linkage for 18 categories of traditional occupations that are heavily represented in urban informal economies.

Urban governance and the 74th Constitutional Amendment are central to addressing urban challenges. The 74th Constitutional Amendment Act (1992) added the Twelfth Schedule listing 18 functions that can be delegated to Urban Local Bodies (ULBs), mandated ward committees for citizen participation, required reservation of one-third seats for women (now 50 percent in many states) in ULB councils, and established State Finance Commissions and State Election Commissions for ULBs. However, actual devolution of functions, finance, and functionaries to ULBs has been highly uneven across states: many functions remain with state government departments and parastatals; ULBs have limited own-revenue sources (primarily property tax, which is poorly assessed and poorly collected in most cities); and transfers from state and central governments are inadequate and uncertain. The result is weak urban local governments unable to plan and execute the scale of investment needed for India's cities. The 15th Finance Commission for the first time made urban local government grants conditional on basic governance reforms (constitutional mandates, audit, and publication of accounts), recognising that fiscal capacity and governance quality are inseparable challenges for Indian cities.
