Interpretation

What this ranking measures—and what it does not

Definition

A median age of 18 means half the population is younger than 18 and half is older. It is not the average age and does not describe the age of the largest cohort.

Why it matters

Very young age structures create momentum: large cohorts moving into adulthood can sustain growth even after fertility begins to fall. They also increase near-term demand for schooling, health services, and future jobs.

Read with care

A low median age is not a development score. National medians conceal differences within countries and say nothing by themselves about education, health, income, or opportunity.

What stands out in the 2026 data

Central African Republic leads with 14.6 years, while Uganda is tenth at 17.1 years. Among the top 20 entries, Africa appears most often, with 19 countries or areas.

Those positions describe this particular indicator and year. They do not imply that every country near the top has the same population pyramid or demographic path. Open the profiles below to compare the underlying cohorts.

  1. Central African Republic — rank 1, 14.6 years; under age 15 48.2%.
  2. Somalia — rank 2, 15.6 years; under age 15 46.5%.
  3. Chad — rank 3, 15.7 years; under age 15 46.0%.
  4. Niger — rank 4, 15.7 years; under age 15 45.8%.
  5. Democratic Republic of the Congo — rank 5, 15.9 years; under age 15 45.8%.

Questions about this ranking

Which country ranks first for median age?

Central African Republic ranks first in this comparison with 14.6 years. The ranking uses the UN WPP 2024 medium scenario for 2026.

Is 2026 observed population data?

No. In World Population Prospects 2024, historical estimates run through 2023 and values from 2024 onward are projections.

Why might another source show a different rank?

Sources can use different reference dates, revisions, country definitions, estimation methods, or projection scenarios. Close ranks can also change after revisions.
