IDA only: Age dependency ratio, young (% of working-age population)

Key figures

What the numbers say

In 2025, IDA only's age dependency ratio, young (% of working-age population) fell 0.67 percentage points on 2024 (from 64.77% to 64.1%).

Across the 30 yearly changes before that (1995 to 2024), the average change was −0.58 percentage points and a typical year strayed about 0.1 percentage points from that (the standard deviation). This year's change was 0.9 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 0.62 percentage points in 1964 and the biggest yearly fall was 0.75 percentage points in 2016. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2016 to 2025 the straight-line trend is downward, about 0.67 percentage points a year. A straight line explains 100% of the movement over 10 observed years.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

A straight-line projection, tested first

Extending that straight line gives about 62.08% for 2028. We show this only because the same method, fitted on earlier years, predicted 2023 to 2025 better than "no change" would have: its average miss was 0.13%, against 1.43% for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.

What this measures

Age dependency ratio, young, is the ratio of younger dependents--people younger than 15--to the working-age population--those ages 15-64. Data are shown as the proportion of dependents per 100 working-age population.

Limitations: Because the five-year age group is the cohort unit and five-year period data are used in the United Nations Population Division's World Population Prospects, interpolations to obtain annual data or single age structure may not reflect actual events or age composition. For more information, see the original source.

Regional and income-group figures are computed by the World Bank as a weighted average.
