How many people in the world are 35 years old?

Roughly 116 million, about 1.4% of the world. The UN publishes five-year groups, so this is a share of the 35 to 39 group, not a direct count.

What percentage of the world is under 35?

56% of the world's people are younger than 35, and 43% are older. The median age of the world is 30.6 (UN, 2024): half of all living people are younger than that.

What is the median age of the world?

30.6 years in 2024, by the UN's World Population Prospects. It ranges from 14.4 in the Central African Republic to 49.4 in Japan. The country whose median age is closest to 35 is the Bahamas, at 35.0: half the people there are younger than that. The world's median is 30.6, so 35 is 4.4 years above it.

How many people are older than 35?

About 3.5 billion people are older than 35, 43% of the world. 4.5 billion, 56%, are younger, and roughly 116 million are 35 right now. The world's median age is 30.6, so 35 is in the older half.

Percentile is the share of the world's people younger than this age. “1 in X” counts the rarer side: people at or beyond this value above the median, at or under it below. Counts come from the UN's five-year age groups, spread evenly inside each group. No normal curve; the age test uses one, so its number differs by a few points.

What this means

World life expectancy at birth is 73.2 years (70.5 for men, 75.9 for women, UN). At 35 that leaves about 38 years on a crude subtraction. Real life tables give more at older ages, because you have already dodged the risks of the years before.
The country whose median age is closest to 35 is the Bahamas, at 35.0: half the people there are younger than that. The world's median is 30.6, so 35 is 4.4 years above it.
About 116 million people are 35 right now. Standing in a line half a metre apart they would stretch 58,155 km, 1.5 times around the equator.
The counts come from the UN's five-year age groups for 2023, spread evenly inside each group. Our age test uses a normal curve with mean 30 and SD 18 instead, so its percentile differs from this one by a few points.
