What might link these
The inverse correlation suggests that countries with a larger proportion of 14-year-old females might have lower service sector value added, or vice versa. This could be linked to demographic structures impacting labor force participation or educational focus.
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 strong negative correlation after controlling for population and GDP could still be driven by unmeasured socioeconomic or cultural factors, not a direct link between the indicators themselves.
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.
