03The whole field at once
The spread
222 countries, one dot each, on one scale — further right is a higher value. Half the countries are above 22.712%; a quarter are above 34.123%, and a quarter below 16.611%. The bar in each row marks that continent’s middle country.
04All 222 ever measured
Every country
In order, highest value first. No rank or position is shown: too many countries share the same value for an order to mean anything. Neither end is better. A high share means many children for every adult of working age — a cost today and a workforce tomorrow at once. A low share usually marks low birth rates and an ageing society; the very lowest readings include small states whose resident populations are unusual, which is a fact about who lives there rather than about families.

Over time
Each point is one year's estimate, 1950 to 2023, as restated by the 2024 revision. The share falls as birth rates fall, and it falls first: the decline among children shows up decades before the rise in the share of people aged 65 and over.

08The measure
About population under 15
The share of a country's population aged under 15 is the plainest measure of how young a population is. It tells a government how many school places, vaccinations and, a few years later, jobs it must plan for.
What the number is: Share of the total population aged 0–14 (%).
What it does not measure
It counts ages, not circumstances: it says nothing about whether those children are in school, healthy or provided for.

11Questions
Population under 15: questions and answers
Which country has the highest population under 15?
Central African Republic, at 49.166%, among the 222 countries compared in 2023.
Which country has the lowest population under 15?
Vatican City, at 6.054%, among the 222 countries compared in 2023.
How many countries does the Population Under Age 15 cover?
222 in 2023.
What is the world average population under 15?
This site does not calculate a world average, which would depend on how countries are weighted. In the middle country of the 222 compared in 2023, the figure was 22.712%.
Is this UN DESA Population Division’s own ranking?
No ranking is shown. UN DESA Population Division publishes values only, and too many countries share the same value for an ordering to mean anything, so none is derived.
How often is the Population Under Age 15 published?
This site holds 74 reference years, 1950–2023, all recalculated in UN DESA Population Division’s 2024 report on one method — not 74 separate publications.
Where does the data come from, and can I download it?
From UN DESA Population Division, under CC BY 3.0 IGO. From World Population Prospects 2024, read from the Population Division's own workbook of age-group shares (POP/F06-1), which publishes the share directly at full precision — not rebuilt by adding up the rounded five-year age groups in the CSV files. Projections are excluded. Every edition is on this site’s Datasets pages as a full table, and downloads as a CSV file with every value unrounded.

How this page reads the numbers
- No rank or position is shown: UN DESA Population Division publishes values only, and too many countries share the same value for an ordering to mean anything.
- This statistic has no better end, so the page describes higher and lower values and never calls a country a leader.
- A country is named at an end only when it holds that value alone. Where several share it, the page says how many and names none first.
- Values are stored exactly as published and trimmed only for display. “The middle country” is the median of the countries measured, not a world average.
The file itself, column by column — where it came from, what each column holds, and every edition as a CSV — is on its dataset page.
