United Nations report: Nearly half of the global population has already settled in cities, with the number of mega-cities increasing fourfold.

The "Summary of the 2025 World Urbanization Prospects" report released by the United Nations Department of Economic and Social Affairs on November 18th shows that 45% of the global population of 8.2 billion already live in urban areas. With ongoing urbanization worldwide, this proportion is expected to continue to rise. The report indicates that in 1950, only 20% of the global population of 2.5 billion lived in cities. By 2050, it is projected that two-thirds of global population growth will occur in cities, with the remaining growth distributed in towns.
