A discussion on the need for a National Urbanisation Policy gained attention on 4 November 2026. The concern is that India's urbanisation is expanding beyond officially recognised city boundaries, while planning, infrastructure and municipal governance remain fragmented.
 
Key Facts

• Census 2027: India is retaining the 2011 criteria for classifying urban settlements.
• Urban population (2011 Census): Approximately 377 million.
• World Resources Institute (WRI) India: Highlights the need for a coordinated National Urbanisation Policy.
• Economic Survey 2025–26: Cited estimates suggesting India was already around 63% urban by 2015.
• Peri-urban areas: Areas on the outskirts of cities experiencing rapid urban expansion.
• Around 52% of statutory towns and 76% of census towns reportedly lack master plans.

How Is Urbanisation Currently Classified?
India recognises two categories of urban settlements:
A. Statutory Towns

• Declared urban by a state government under a law.
• Examples: Municipal Corporations, Municipalities and Cantonment Boards.

B. Census Towns
A rural settlement is classified as a Census Town if it satisfies all three criteria:

1. Population of at least 5,000.
2. Population density of at least 400 persons per sq. km.
3. At least 75% of male main workers engaged in non-agricultural activities.

Problem: Many settlements have urban economic and demographic characteristics but continue to be governed as rural areas.
 
Why Is a Unified Policy Needed?

• Fragmented planning: Urban development, transport, housing and water management are handled by different agencies.
• Urban-rural classification gap: Growing settlements may lack municipal services despite having urban characteristics.
• Weak municipal finance: Limited revenue restricts infrastructure development.
• Unplanned expansion: Peri-urban areas face pressure on land, water, sanitation and transport.
• Environmental challenges: Pollution, flooding and waste management require planning beyond municipal boundaries.

Major Recommendations
WRI India's report, Equitable, Productive, Low-Carbon and Resilient System of Cities in India, proposes seven systemic transformations:

1. Standardise the definition and classification of urban settlements.
2. Modernise spatial and regional planning.
3. Improve public and private financing for urbanisation.
4. Strengthen coordination between different levels of government through a proposed National Urbanisation Council.
5. Plan according to functional regions such as city regions, river basins and airsheds.
6. Create incentives for political leaders to undertake urban governance reforms.
7. Promote knowledge-sharing and local innovation.
