What might link these
The strong correlation might be due to the fact that males aged 35-39 are a subset of the broader working-age population. A careful reader should consider that urbanization rates could be a confounder, as countries with higher urbanization might have different population distributions. The relationship could be influenced by various socioeconomic 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 the two age groups without considering other demographic and economic factors at play.
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.
