Urbanization is the most visible transformation of India in the 21st century. While India remains predominantly rural (~63%), its urban population is larger than the entire population of the European Union.

Causes of Rapid Urbanization
- Push factors: Rural poverty, declining agricultural incomes, fragmentation of landholdings, lack of non-farm employment
- Pull factors: Better employment opportunities (manufacturing, services), education, healthcare, social mobility
Million-Plus Cities (Urban Agglomerations)
India has 53 million-plus UAs (Urban Agglomerations/Cities), accounting for 42% of the urban population.

Challenges of Urbanization
Housing and Slums
| Challenge |
Magnitude |
| Slum population |
~65 million (2011 Census: 13.7 million households) |
| Urban housing shortage |
~10 million units (2023, MoHUA) |
| Slum proportion |
17% of urban households; Mumbai: 40%+ live in slums |
Urban Infrastructure Gaps
| Sector |
Gap |
Impact |
| Water supply |
35% of households lack piped water connection |
Groundwater depletion; tanker dependency |
| Sewerage |
70% of sewage untreated (especially smaller cities) |
River pollution (Ganga, Yamuna, Musi) |
| Solid waste |
30% solid waste collected but untreated |
Landfills overflowing; plastic pollution |
| Transport |
Metro in only 15 cities; bus fleet inadequate |
Congestion, air pollution |
| Health |
Public hospitals overcrowded; primary care insufficient |
Out-of-pocket expenditure rising |
Urban Poverty and Inequality
- Gini coefficient in Indian cities ~0.40-0.45 (moderate-to-high inequality)
- 25% of urban population below poverty line (multi-dimensional poverty index)
- Migrant workers lack access to social security (ration cards, PDS, health)
Smart Cities Mission
- Launched: June 25, 2015 (100 smart cities, 5-year timeline)
- Approach: Area-based development (retrofit, redevelop, greenfield) + pan-city solutions (ICT)
- Funding: ₹48,000 crore central + matching state + PPP
