What might link these
The relationship between total reserves minus gold per capita and the proportion of females aged 30-34 per unit of GDP might be influenced by a country's economic development stage, which could affect both indicators. A careful reader should consider education as a likely confounder, as it can impact both economic participation and reserve management. The correlation suggests a complex interaction between demographic and economic factors.
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. This correlation could mislead by implying a direct relationship between reserve management and demographic ratios, when in fact, both may be driven by broader economic and societal factors.
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.
