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). 83 is past it, which is not a deadline: someone who has reached 83 has already survived the risks a newborn still faces, and in rich countries can expect several more years.
No country has a median age this high. The oldest is Japan, at 49.4; the world's median is 30.6, so 83 is 52 years above it.
About 18 million people are 83 right now. Standing in a line half a metre apart they would stretch 8,863 km, 22% of the way 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.
