What might link these
Wealthier nations often have older populations due to better healthcare and lower birth rates, while aging societies may invest more in productivity-enhancing technologies. However, correlation alone doesn’t prove direction—some high-GDP countries attract young workers, diluting the link.
Why this is not proof of anything
This is a correlation across countries, not an experiment. It cannot show that either indicator causes the other, and both may simply follow a third thing. The partial correlation remains strong but doesn’t account for other factors like education or healthcare quality that could drive both indicators.
The second figure above repeats the measurement with national population and income held constant. It is the more conservative number: a relationship that largely disappears there was mostly telling you that larger, richer countries have more of most things.
How this was measured
Both indicators were ranked across every country reporting each, and the two rankings compared — ranks rather than raw values, because a handful of very large countries can otherwise manufacture a relationship on their own. The calculation is arithmetic over figures already published on this site; the commentary above is drafted from the two indicator names and the resulting coefficients.
