What might link these
Countries with a higher proportion of older males relative to GDP also tend to have higher primary school enrolment per unit of GDP. This might reflect differing demographic structures or levels of development influencing both population aging and educational investment.
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, while controlling for population and GDP, does not account for potential confounding factors like government spending on social services or healthcare.
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.
