What the numbers say
In 2025, Guam's age dependency ratio (% of working-age population) rose 1.01 percentage points on 2024 (from 62.83% to 63.83%).
Across the 30 yearly changes before that (1995 to 2024), the average change was +0.3 percentage points and a typical year strayed about 0.62 percentage points from that (the standard deviation). This year's change was 1.1 standard deviations above that average, so it was larger than a typical year, though not out of the range seen before.
On record, the biggest yearly rise was 1.88 percentage points in 1961 and the biggest yearly fall was 1.56 percentage points in 1975. 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 upward, about 1.19 percentage points a year. A straight line explains 100% of the movement over 10 observed years.

A straight-line projection, tested first
Extending that straight line gives about 66.85% 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 1.69%, against 2.44% 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.

How it compares
In 2025, Guam had the 59th highest value of the 217 economies reporting that year. Higher is not always better: for some indicators the lowest value is the one to aim for. See the full ranking.

What this measures
Age dependency ratio is the ratio of dependents--people younger than 15 or older than 64--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.
