Housing Shortages in India: Understanding Causes and Conditions

Behind India’s gleaming city skylines and booming real estate markets lies a quieter, more troubling reality: millions of families do not have a decent place to call home. Housing shortage is not just about empty land or unbuilt apartments. It is about overcrowded rooms, leaking roofs, unsafe slums, and the daily struggle of low-income families to secure even basic shelter. Understanding this crisis is essential for anyone studying urbanisation, public health, or social policy, because where people live shapes how they live.

The scale of India’s housing shortage 🔗

According to estimates by the Ministry of Housing and Urban Poverty Alleviation and successive Technical Groups on Urban Housing Shortage, India’s total housing shortage stood at around 24.71 million units, with the urban shortage later estimated at 18.78 million units for the 2012-17 plan period. This number is not a dry statistic. It represents real families squeezed into single rooms, sharing toilets with dozens of neighbours, or living in structures made of tin sheets and tarpaulin.

What makes this shortage especially serious is its concentration among the poorest. Reports such as the KPMG-NAREDCO study on urban housing note that nearly the entire urban housing deficit lies within the Economically Weaker Sections (EWS) and Low Income Groups (LIG). Families earning up to ₹3 lakh annually (EWS) and between ₹3 and 6 lakh annually (LIG) carry the heaviest burden, even though they form the backbone of the urban informal workforce, working as construction labour, domestic help, street vendors and factory workers.

Quantitative and qualitative dimensions 🔗

Housing shortage in India is measured in two ways. The first is the simple gap between the number of households and the number of acceptable housing units. The second, often more revealing, is the qualitative shortage: homes that exist but are unfit to live in. The Ministry of Statistics and Programme Implementation notes that a significant share of the shortage is driven by congestion (too many people per room) and obsolescence (homes in dilapidated condition). In other words, India does not just need more houses; it needs better houses.

Housing conditions on the ground 🔗

Census 2011 found that around 65.5 million Indians lived in slums, roughly 17% of the urban population. As highlighted by Down To Earth, the true figure today is likely far higher because no fresh slum census has been conducted since then, even as cities have grown rapidly.

Overcrowding and lack of basic amenities 🔗

A typical low-income household in cities like Mumbai or Delhi often shares one or two rooms among five or more members. The Technical Group on Urban Housing Shortage defines overcrowding as more than two persons per room, and by that standard a large share of EWS households live in overcrowded conditions. The consequences extend well beyond inconvenience. Overcrowding increases the spread of respiratory infections like tuberculosis, raises stress and domestic conflict, and leaves children with no quiet space to study.

Beyond space, the question of amenities is equally pressing. Even when a family has a roof, that roof may not come with piped water, a private toilet, or reliable electricity. National data show that a large proportion of urban households still lack water within their premises or depend on shared sanitation, conditions that directly affect maternal and child health.

Tenure insecurity 🔗

A less visible but equally damaging problem is the lack of secure tenure. Most slum residents do not legally own the land they live on, which means they can be evicted at short notice. Without legal title, they cannot easily access loans, formal water and electricity connections, or government services. As the Government of India’s housing chapter notes, access to land and secure tenure is fundamental to adequate shelter and to a family’s ability to invest in improving its home.

What is driving the shortage? 🔗

The housing crisis in India is not the result of one cause but a tangle of demographic, economic, and policy factors.

Rapid urbanisation and migration 🔗

India is among the fastest urbanising countries in the world. The UN projects that India’s urban population will nearly double from 461 million in 2018 to about 877 million by 2050. Much of this growth is driven by rural-to-urban migration, as workers leave villages in states like Bihar, Uttar Pradesh, and Odisha in search of jobs and better wages. As analyses on slum growth point out, this influx far outpaces the supply of affordable housing, and slums become the default option for new arrivals.

Inadequate supply of affordable housing 🔗

The private real estate sector has historically focused on building for middle and high-income buyers, where margins are larger. Land in Indian cities is expensive, regulations are complex, and approvals are slow, all of which push developers towards premium projects. The result is a mismatch: thousands of unsold luxury flats exist alongside a desperate shortage of homes affordable to those earning under ₹25,000 a month. Interestingly, Census 2011 also recorded around 11.1 million vacant urban houses, often used as investment assets, which highlights how the market fails to align supply with genuine need.

Low incomes and unaffordable credit 🔗

For most EWS and LIG families, formal home loans are out of reach. Their incomes are irregular, they often lack documents like salary slips, and banks see them as risky borrowers. Even subsidised schemes can miss them, as noted in a study published in Policy and Society, which found that the Credit Linked Subsidy Scheme effectively favoured households with stable, formal incomes, leaving the most vulnerable behind.

Weak urban planning and infrastructure 🔗

Most Indian cities have grown faster than their master plans. Roads, drainage, sewage, water supply, and public transport struggle to keep up with the new population. When a city cannot deliver basic services, low-income housing tends to come up informally, on floodplains, near railway tracks, or on the city’s edges, often without legal protection. The growth of slums in India is closely linked to this gap between urban planning ambitions and ground realities.

Land scarcity and high prices 🔗

Urban land prices in India are among the highest in the world relative to incomes. Combined with restrictive Floor Space Index norms, this makes it difficult to build dense, affordable housing close to job centres. Workers are then pushed to peripheral areas, sometimes spending three to four hours a day commuting, which eats into earnings, family time, and well-being.

Health and social consequences 🔗

Housing is a core determinant of population health. Poor housing conditions are tied to higher rates of respiratory illness, water-borne diseases, malnutrition, and mental stress. Women and children are particularly affected. Female-headed households face additional barriers in renting and owning homes due to discrimination and lower average incomes, and crowded settlements without safe sanitation increase the risk of gender-based violence.

Children in inadequate housing show poorer school attendance and learning outcomes. Studies on slum populations report that diseases like tuberculosis, dengue, and diarrhoeal infections are markedly more common where housing is overcrowded and sanitation is poor. From a family health perspective, fixing housing is therefore not a separate issue from health, education, and gender equity. It is a foundation for all of them.

Policy responses so far 🔗

India has not been silent on housing. From the Indira Awas Yojana in the mid-1980s to the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) in 2005 and the Rajiv Awas Yojana, several schemes have tried to expand affordable housing and improve slums. The current flagship initiative is the Pradhan Mantri Awas Yojana-Urban (PMAY-U), launched in June 2015 with the goal of “Housing for All”.

How PMAY works 🔗

PMAY-U operates through four verticals: In-situ Slum Redevelopment (ISSR) using land as a resource, the Credit Linked Subsidy Scheme (CLSS) offering interest subsidies on home loans, Affordable Housing in Partnership (AHP) with private and public agencies, and Beneficiary-led Construction (BLC) providing direct assistance for individual house construction. A notable feature is the requirement that the house be owned by, or co-owned with, a female member of the family, a meaningful step towards gender-equitable property ownership.

According to the Press Information Bureau, PMAY-U has sanctioned over 1.18 crore houses, with more than 83.67 lakh completed as of June 2024. In August 2024, the Cabinet approved PMAY-U 2.0, which aims to assist an additional one crore urban households over five years and introduces affordable rental housing and a renewed Interest Subsidy Scheme.

Why progress is uneven 🔗

Despite the scale of these schemes, gaps remain. Beneficiary identification is often weak, particularly for migrant workers and people without local documents. Construction is sometimes located far from job centres, leaving completed houses unoccupied. As the Policy and Society analysis highlights, subsidy designs can quietly exclude those whose incomes are too informal or unstable to qualify. Slum rehabilitation projects can also displace residents from livelihood networks if not designed with community participation.

What can be done? 🔗

Tackling India’s housing shortage will need more than one big scheme. A multi-pronged approach is needed.

Expanding affordable rental housing 🔗

Many migrant workers do not want to buy homes; they need affordable, dignified rentals close to work. The Affordable Rental Housing Complexes (ARHC) initiative under PMAY-U is a step in this direction and deserves stronger implementation, including incentives for private players to enter low-cost rental markets.

Inclusive slum rehabilitation 🔗

Rather than evicting slum residents, in-situ redevelopment that uses the existing land and involves residents in design tends to work better. Secure tenure, even where full ownership is not possible, gives families the confidence to invest in their homes and access services.

Reforming land and building rules 🔗

Reforms in land use, Floor Space Index norms, and faster building approvals can release more land for affordable housing close to employment hubs. Transparent land records and digitised approvals reduce corruption and delays.

Strengthening financial inclusion 🔗

Innovative finance models, including micro-mortgages, community savings groups, and rent-to-own arrangements, can help informal-sector families step onto the housing ladder. Banks and housing finance companies need products designed for irregular incomes rather than only salaried borrowers.

Linking housing with health, water, and sanitation 🔗

Housing schemes work best when integrated with programmes like Swachh Bharat Mission for sanitation, Ujjwala Yojana for clean cooking gas, Jal Jeevan Mission for piped water, and AMRUT for urban infrastructure. A pucca house with no water connection is only half a solution.

Better data for better policy 🔗

Finally, India urgently needs an updated slum and housing census. Without fresh data, policies are based on 2011 numbers in a country whose cities have transformed dramatically. Accurate, current information would help target schemes more effectively and hold implementing agencies accountable.

What do you think? If you had to choose between building a million new affordable houses on the outskirts of a city or upgrading a million existing slum homes in their current location, which would do more for residents’ health and livelihoods, and why? And how can policies make sure that women, migrants, and informal workers are not left out of the next phase of India’s housing story?
