The GS I syllabus mentions "urbanization, their problems and their remedies" as part of Indian society, and the theme reappears in GS II (urban governance) and GS III (infrastructure). It is also a favourite essay theme. To write well about it, you need numbers you can trust, a sense of how India's urbanisation differs from the textbook model, and a clear view of the problems and remedies.
How India defines "urban"
The Census recognises two kinds of urban areas:
- Statutory towns — places with a municipality, corporation, cantonment board or notified town area committee.
- Census towns — places that are not statutory towns but meet three criteria:
- a population of at least 5,000;
- at least 75 per cent of the male main workforce engaged in non-agricultural work;
- a population density of at least 400 persons per square kilometre.
This distinction matters, because census towns are urban in character but are often still governed as villages.
The numbers
The most recent complete Census, in 2011, found that about 31 per cent of India's population — some 377 million people — lived in urban areas, up from about 28 per cent in 2001. The number of census towns jumped from roughly 1,360 in 2001 to about 3,900 in 2011, one of the most striking changes of that decade.
The next Census will provide a much-needed update; until then, urban estimates rely on projections and surveys.
What drives urbanisation in India
| Driver | How it works |
|---|---|
| Natural increase | Births in urban areas — a major component of urban growth |
| Rural–urban migration | Push factors (agrarian distress, lack of work) and pull factors (jobs, education, services) |
| Reclassification | Villages becoming census towns as their economies change |
| Expansion of city boundaries | Cities absorbing surrounding villages |
India's urbanisation has been slower than many expected, partly because a large share of rural–urban movement is circular or seasonal migration rather than permanent settlement.
Distinctive features of Indian urbanisation
- Top-heavy growth — large metropolitan areas and million-plus cities have grown fast, while many small towns have lagged in infrastructure.
- Peri-urbanisation — rapid, often unplanned growth on the fringes of cities, where land is cheaper and regulation weaker.
- "Subaltern" urbanisation — growth of small towns and census towns driven by local economies rather than by metropolitan expansion.
- Informality — a large share of urban workers are in the informal sector, and much housing is informal.
- Regional variation — states such as Tamil Nadu, Kerala, Maharashtra and Gujarat are far more urbanised than Bihar or Odisha.
The problems
Housing and slums
The 2011 Census counted around 65 million people living in slums. Slums reflect a gap between urban land and housing markets and the incomes of workers the city depends on.
Infrastructure and services
Water supply, sewerage, solid waste management and public transport have not kept pace with growth in many cities.
Urban flooding
Heavy rainfall combined with encroached wetlands and lakes, blocked drains and concrete surfaces has made flooding a recurring problem in cities such as Mumbai, Chennai, Bengaluru and Hyderabad.
Heat and pollution
The urban heat island effect — cities being warmer than surrounding areas because of concrete, asphalt and fewer trees — intensifies heatwaves. Air pollution is severe in many cities, especially in the Indo-Gangetic plain.
Governance
The 74th Amendment (1992) gave municipalities constitutional status, but in many cities:
- mayors have limited executive power;
- key functions (planning, water, transport) remain with state-level agencies;
- municipal finances depend heavily on transfers, with weak property tax collection.
Policy responses
| Programme | Launched | Focus |
|---|---|---|
| Smart Cities Mission | 2015 | Area-based development and technology-enabled services in selected cities |
| AMRUT | 2015 | Basic urban infrastructure — water supply, sewerage, green spaces |
| Pradhan Mantri Awas Yojana – Urban | 2015 | Affordable housing |
| Swachh Bharat Mission – Urban | 2014 | Sanitation and solid waste management |
Scholars and committees have also called for stronger municipal governments with fiscal autonomy, metropolitan planning bodies, better land-use planning that protects water bodies, rental housing for migrants, and a greater focus on small and medium towns.
Urbanisation as opportunity
Cities are also where productivity, innovation and upward mobility concentrate. A large share of India's GDP is generated in urban areas. The goal is not to slow urbanisation but to make it planned, inclusive and resilient.
Practice questions
- Prelims-type: What are the criteria for a census town?
- Mains-type (150 words): What is meant by "hidden urbanisation" in India? Why does it matter for governance?
- Mains-type (250 words): "Urban flooding in India is more a failure of planning than of rainfall." Discuss.
