What might link these
The relationship between young female population and elderly female population per unit of GDP might be influenced by demographic transitions and societal structures. A careful reader should consider factors like healthcare systems and social security, which could affect both indicators. Education level is a likely confounder.
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 link between the two age groups, when in fact it may be driven by underlying demographic or economic trends.
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.
