What might link these
The relationship between the growth rate of males aged 50-54 and population by income level may be driven by demographic changes or economic factors. A careful reader should consider that urbanization could be a confounder, as it can affect both indicators. The correlation suggests a potential pattern, but its underlying causes need further exploration.
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 these indicators when other factors, such as government policies or technological advancements, might be the actual drivers.
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.
