Global Population to Peak at 10.3 Billion in 2080s, Then Decline

UN report projects a significant demographic shift with earlier and lower peak due to declining fertility rates in major countries.

World population expected to rise from 8.2 billion in 2024 to 10.3 billion in the mid-2080s.
Population will decline to 10.2 billion by 2100, 6% lower than previous estimates.
China, currently the second most populous country, will see its population halve by 2100.
By 2080, people aged 65 and older will outnumber those under 18 globally.
Countries with growing populations face the challenge of balancing environmental impacts and resource needs.
