World population
World population in 2026 is about 8.2 billion. India is the most populous country. Growth is slowing in East Asia and still high in parts of Africa.
UN estimates put world population near 8.2 billion in 2026. The eight-billion mark was passed in 2022. Growth has slowed compared with the 1960s, but the total is still rising.
Most extra births this decade are expected in sub-Saharan Africa and parts of South Asia. East Asia is ageing: China, Japan and South Korea have very low fertility. Europe is similar.
Population is not destiny. Health, education and jobs decide whether a large young population is a bonus or a strain. Use the country ranking page for the top ten lists.

How many people are in the world in 2026?
About 8.2 billion on the UN medium estimate. Live counters on the web are models, not a headcount.
When will population peak?
UN medium scenarios often show a peak later this century, then a slow decline. The year moves when fertility assumptions change.
Is the world overpopulated?
That is a values question. Facts: total is still rising, emissions and consumption are uneven, and some countries already have shrinking workforces.
