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 12 that leaves about 61 years on a crude subtraction. Real life tables give more at older ages, because you have already dodged the risks of the years before.
- No country has a median age this low. The youngest is the Central African Republic, at 14.4; the world's median is 30.6.
- About 136 million people are 12 right now. Standing in a line half a metre apart they would stretch 68,169 km, 1.7 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.
