India's Urbanisation Trajectory

India's urban population has grown steadily over the past century, though the pace of urbanisation has been slower than comparable economies at similar income levels.

Year Urban Population % of Total Population
1951 6.2 crore 17.3%
1981 15.9 crore 23.3%
2001 28.6 crore 27.8%
2011 (Census) 37.7 crore 31.2%
2024 (World Bank estimate) ~53.5 crore ~36.9%

India's urban population surpassed 50 crore by the early 2020s, making it one of the world's largest urban populations in absolute terms. Urban population growth was approximately 2.3% per year in 2024.

UN Projections: India is expected to add approximately 416 million urban residents between 2018 and 2050, the highest absolute increment in urban population of any country — exceeding even China's projected urban growth.

Definitions: Urban India

India uses multiple definitions of "urban" for administrative and analytical purposes:

Type Definition
Statutory Towns Places with a municipal body (Municipal Corporation, Municipal Council, Town Panchayat, etc.) notified by state law
Census Towns Places that satisfy Census criteria: (a) minimum population of 5,000; (b) at least 75% of male main workers engaged in non-agricultural activities; (c) population density of at least 400 persons per sq km — but have no municipal body
Urban Agglomeration (UA) A continuous urban spread comprising a town and its adjoining outgrowths or two or more physically contiguous towns
Out-growths (OG) A viable unit such as a railway colony, university campus, or industrial township located adjacent to a statutory town

The Census 2011 counted 7,935 towns (including Census towns) and 475 Urban Agglomerations. The explosive growth of Census towns (from 1,362 in 2001 to 3,894 in 2011) was a striking finding — much of India's urbanisation was occurring in settlements not yet formally recognised as urban.

Push and Pull Factors of Rural-Urban Migration

Push factors (conditions in rural areas that drive out-migration):

  • Agricultural distress (droughts, crop failures, declining farm incomes)
  • Land fragmentation; excess agricultural labour
  • Limited access to quality education and healthcare in rural areas
  • Social discrimination (caste, gender)
  • Natural disasters and climate-related vulnerabilities

Pull factors (conditions in urban areas that attract migrants):

  • Higher wage employment in manufacturing and services
  • Better educational and health infrastructure
  • Social mobility; escape from caste hierarchies
  • Access to markets and economic opportunities

The Urban Housing Crisis

Housing Shortage

India faces a chronic housing deficit, particularly in the lower-income segments. Based on a technical group report for the 12th Five Year Plan, urban housing shortage was estimated at 1.87 crore units — with 96% of the shortage affecting EWS (Economically Weaker Section) and LIG (Low Income Group) households.

Housing shortage is driven by:

  • Rapid population growth in cities
  • Unaffordable formal housing (land prices, construction costs)
  • Weak rental market (archaic Rent Control Acts discourage supply)
  • Inadequate serviced land for housing
  • Slow urban local body planning and approval processes

Slums

Census 2011 Definition: A slum is a compact area of at least 300 people or about 60-70 households living in poorly built, congested tenements in unhygienic conditions, usually with inadequate infrastructure and lacking proper sanitary and drinking water facilities.

As per Census 2011, 65.49 million people lived in slums in India, accounting for 17.4% of the urban population. India had 33,510 slum localities across 2,613 towns in 2011.

Key Urban Housing Schemes

Pradhan Mantri Awas Yojana — Urban (PMAY-U)

PMAY-U 1.0 was launched in June 2015 under the "Housing for All by 2022" mission. It aimed to provide affordable housing to urban poor through four verticals:

Vertical Target Beneficiary Approach
Beneficiary Led Construction (BLC) EWS families with own land Central assistance for new construction/enhancement
Affordable Housing in Partnership (AHP) EWS/LIG families Government partners with private developers for affordable housing projects
Credit Linked Subsidy Scheme (CLSS) EWS, LIG, MIG Interest subsidy on home loans (now continued under PMAY-U 2.0 as ISS)
In-Situ Slum Redevelopment (ISSR) Slum dwellers Uses land as a resource; private developers get cross-subsidised projects

PMAY-Urban 2.0 (Launched September 2024)

The Union Cabinet approved PMAY-U 2.0 with effect from 1 September 2024, targeting 1 crore families over 5 years with an investment of ₹10 lakh crore (Central assistance of ₹2.50 lakh crore).

Four verticals under PMAY-U 2.0:

  1. Beneficiary Led Construction (BLC) — for EWS families with own land; also covers landless beneficiaries (states to provide land rights/pattas)
  2. Affordable Housing in Partnership (AHP) — state partnerships with developers
  3. Affordable Rental Housing (ARH) — new vertical targeting urban migrants and working class in rental accommodation
  4. Interest Subsidy Scheme (ISS) — 4% interest subsidy on first ₹8 lakh of home loans up to ₹25 lakh for EWS/LIG/MIG; house value ceiling of ₹35 lakh; loan tenure up to 12 years

Income eligibility:

  • EWS: annual income up to ₹3 lakh
  • LIG: ₹3–6 lakh
  • MIG: ₹6–9 lakh

As of February 2026, the CSMC (Central Sanctioning and Monitoring Committee) approved an additional 2.88 lakh houses under PMAY-U 2.0.

Earlier Scheme: Rajiv Awas Yojana (RAY)

Rajiv Awas Yojana (2009-2014 pilot, 2013 onwards) was the predecessor scheme focused specifically on slum-free cities. It envisioned bringing all existing slums within the formal system and creating conditions for a slum-free India. RAY was subsumed under PMAY-U in 2015.

Smart Cities Mission

Launched in June 2015, the Smart Cities Mission aims to promote cities that provide core infrastructure, clean and sustainable environment, and a quality of life to their citizens through the application of smart solutions.

Feature Detail
Number of cities 100 cities selected through a competitive challenge process
Implementing entity Special Purpose Vehicles (SPVs) at city level
Areas of development Smart roads, command and control centres, smart meters, CCTV surveillance, e-governance, smart parking, public Wi-Fi
Area-based development Retrofitting, redevelopment, or Greenfield development
Mission period Initially 5 years (2015-2020); extended; outcomes being evaluated as of 2025-26

The Mission has been critiqued for focusing on physical infrastructure over inclusive development and for neglecting the needs of the urban poor and slum dwellers.

AMRUT 2.0 (Atal Mission for Rejuvenation and Urban Transformation)

AMRUT 2.0 was launched in October 2021 to make cities self-reliant in water and begin moving towards a circular economy. It covers 500 cities (compared to AMRUT 1.0's 500 cities launched in 2015).

Focus areas: Universal coverage of water supply and sewage connections, rejuvenation of water bodies, green spaces, peri-urban areas, and reducing non-revenue water.

Urban Governance: 74th Constitutional Amendment

The 74th Constitutional Amendment Act, 1992 gave constitutional status to Urban Local Bodies (ULBs) — Municipalities and Municipal Corporations. Key provisions:

  • Mandates elections to municipal bodies
  • Three-tier structure: Nagar Panchayat (transitional areas), Municipal Council (smaller urban areas), Municipal Corporation (large cities)
  • 12th Schedule lists 18 functions that may be transferred to municipalities (though actual transfer depends on state legislation)
  • Reservation of seats for SC/ST and women (at least 1/3rd)
  • Constitution of State Finance Commissions (on lines of Central Finance Commission) to devolve funds to ULBs
  • District Planning Committee and Metropolitan Planning Committee for integrated planning

Urban Challenges

Challenge Dimension
Urban sprawl Unplanned expansion; peri-urban areas grow without services; farmland conversion
Urban heat island effect Dense cities are 2-5°C hotter than surroundings; worsened by climate change
Urban flooding Concretisation reduces permeability; storm drains inadequate; Chennai (2015), Mumbai recurrent
Infrastructure deficit Water supply gaps, sewage treatment capacity far below need, solid waste management failures
Affordable housing gap Formal housing unaffordable for EWS/LIG; housing shortage persists despite PMAY
Informal economy ~80% of urban workers in informal sector; lack social protection
Urban governance weakness ULBs lack adequate staff, funds, and functions; state governments reluctant to devolve
Urban poverty Multidimensional — poor housing, health, education, vulnerability to eviction

The Economic Survey 2025-26 specifically flagged long-standing supply-side challenges in land, housing, and transport as key sources of urban stress constraining India's economic potential.

Exam Strategy Note

For GS1 Mains, urbanisation intersects with migration (GS1 population), inequality, housing rights (Directive Principles), and social stratification. For GS2, urban governance (74th Amendment, ULBs, SPVs) is directly relevant. For GS3, urban infrastructure, smart cities, and PMAY connect to economic development. Always use current data — Census 2011 is the last Census, but World Bank and UN projections are reliable for current estimates. PMAY-U 2.0 (September 2024) is the current scheme — ensure answers reflect the 2.0 structure.
