What is the current world population in 2026?
The world population is about 8,300,678,395 as of 1 January 2026, according to the UN World Population Prospects 2024 medium variant. It is growing by roughly 68.4M people a year, or about 2.2 every second.
Which country has the largest population?
India, with 1,463,865,525 people — about 17.6% of everyone alive. China is second with 1.41B.
How fast is the world population growing?
About 0.82% a year. That rate has fallen by more than half since the late 1960s, when it exceeded 2%. Because the population base is far larger now, the absolute number added each year has fallen much less than the rate.
What is the largest city in the world?
Tokyo, Japan, with a metropolitan population of about 37,400,068. Rankings differ depending on whether they measure the metro area or the city proper — by city proper the answer is different.
When will the world population peak?
Under the UN medium variant, world population peaks at about 10.3B around 2084, then slowly declines. The high and low variants disagree substantially — the low variant has population falling from the 2050s.
Why is population growth slowing down?
Falling fertility, principally. As child mortality drops, incomes rise and education expands, families get smaller. More than half the world now lives in countries with fertility below the replacement level of about 2.1 births per woman.
How many countries are there in the world?
There are 195 UN member and observer states. This site covers 240 countries and territories, because dependencies and special administrative regions publish their own statistics — which means some populations here are also counted within their administering state.
How accurate are population projections?
Short-run projections are quite reliable, because most people alive in twenty years are already born. Long-run projections depend on fertility assumptions that no one can verify in advance, which is why the UN publishes several variants rather than a single number.
