What might link these
The relationship between aging populations and lower transport service imports might be driven by differences in economic structures or consumption patterns across countries. A careful reader should consider that urbanization rates could be a confounder, as they might influence both the proportion of elderly population and the demand for transport services. This correlation invites further exploration to understand the underlying mechanisms.
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 aging and transport imports, when in fact other factors like urbanization or industry composition might be driving the relationship.
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.
