WHO Warns Urban Population to Reach 70 Percent by 2050, Heightening Global Health Risks

The World Health Organization warns that by 2050 nearly 70 percent of people will live in cities, increasing exposure to health risks.

The World Health Organization (WHO) has warned that nearly 70 percent of the world’s population will be living in urban areas by 2050, intensifying global health challenges.

In a report released on Tuesday, December 30, the WHO said more than 4.4 billion people already reside in cities, marking a historic shift in human settlement patterns.

According to the agency, urban areas are on the frontline of health risks, including air pollution, unsafe transportation systems, inadequate housing, and the growing impacts of climate change.

The WHO’s 2025 global health review noted that the year reflected both significant public health achievements and deep, persistent challenges worldwide.

Rapid urbanization has accelerated in recent decades, particularly in low- and middle-income countries, where infrastructure and health systems often struggle to keep pace with population growth.

Public health experts warn that poorly planned cities can worsen inequality, increase exposure to disease, and heighten vulnerability to heatwaves, flooding, and other climate-related disasters.

Despite widespread budget cuts and rising threats to scientific cooperation, the WHO said it has continued to lead global efforts to address the most pressing health risks facing urban populations.

The organization stressed that evidence-based policymaking, international solidarity, and sustainable urban planning will be critical to protecting health and wellbeing in an increasingly urban world.
