Age
Your age against the world's age pyramid, plus life expectancy for your country. The global median age is 30.9; Japan's is 48.4 and Nigeria's is 18.1.

Life expectancy, United States
Life expectancy at birth for men in United States is 76.9 years, which leaves about 47 years. Someone your age has already dodged childhood, so the real figure is a little higher.
UN World Population Prospects 2024, life expectancy at birth.
Against your country
The median age in United States is 38.9 years. You are 9 years younger than the national median.
World population by age (normal approximation)
In context
A Greenland shark born the same year as you is still a juvenile. They live 400 years or more and reach maturity at about 150. You are well ahead of it.

About this test
You enter your age. The module shows what share of the world's population is younger than you, how you compare to the median age of your country, and how far you are through the life expectancy for your sex. The global comparison uses a normal approximation with mean 30 and SD 18, a rough stand-in for the real age pyramid.
The global median age is 30.9. Japan's is 48.4, Germany's 45.7, Nigeria's 18.1. Someone aged 40 is in the older half almost everywhere except Japan, Italy and Germany.
What is the median age of the world?
30.9 years, from UN World Population Prospects 2024. Half of all living people are under 31. Among the countries in the picker, Japan is oldest at 48.4 and Nigeria youngest at 18.1.
What percentage of people are older than me?
At 30 you are near the middle. At 50, roughly 86% of people are younger than you, using the module's normal approximation (mean 30, SD 18). The true pyramid is skewed, so treat the number as a rough guide.
What is the life expectancy in my country?
Global life expectancy at birth is 70.5 years for men and 75.9 for women (UN WPP 2024). Norway: 81.7 and 84.8. Japan: 81.7 and 87.7. Nigeria: 54.2 and 54.7. The module uses the figure for your country and sex.
