What might link these
The relationship between domestic currency value and the proportion of females aged 65-69 per unit of GDP might be influenced by factors such as pension systems or social security structures that vary by country. A careful reader should consider the potential impact of healthcare systems on life expectancy and thus the demographics. A likely confounder could be the overall healthcare expenditure as a percentage of GDP.
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 currency value and demographic ratios without considering the complex interplay of economic and social 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.
