The World Urbanization Prospects 2025 report was released by the United Nations Department of Economic and Social Affairs (UN DESA).
The report states that 45% of the world’s 8.2 billion people now live in cities.
Two-thirds of global population growth between 2025 and 2050 will occur in cities.
India is one of seven countries expected to drive global city population growth between 2025 and 2050.
India, Nigeria, Pakistan, Democratic Republic of the Congo, Egypt, Bangladesh, and Ethiopia will add over 500 million new urban residents.
India and China together account for nearly 1.2 billion city residents.
Megacities with over 10 million people increased from 8 in 1975 to 33 in 2025.
Highest in Jakarta (42 million), Dhaka (40 million), and Tokyo (33 million), and may rise to 37 by 2050.
Bengaluru is listed among the world’s top 10 most densely populated cities.
It has a population density exceeding 20,000 people per sq km.
Bengaluru is also one of India’s five megacities in the report, along with Delhi, Mumbai, Kolkata, and Chennai.
Out of the world’s 50 most crowded cities, 12 are in India.
The total number of cities worldwide doubled between 1975 and 2025 and may cross 15,000 by 2050 due to rapid growth in Africa and Asia.
Many cities are shrinking even when national populations rise, particularly in China and India, where over one-third of shrinking cities have fewer than 250,000 people.
The report highlights that sustainable urban planning is essential for future development and climate goals.
