What might link these
The relationship between these indicators might be linked to overall demographic trends or education and workforce patterns. A careful reader should consider that factors like access to education or economic opportunities could influence both indicators. A likely confounder could be the overall fertility rate or cultural attitudes towards female education and workforce participation.
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 the two age groups without considering the many societal and economic factors that influence female population demographics.
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.
