What might link these
Industrialized nations likely demand more graphic papers for packaging and printing, while their higher GDP fuels both imports and industrial output. A careful reader should note that correlation does not imply causation—other factors like trade policies or cultural preferences may drive both trends.
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 high rank correlation could reflect broader economic activity rather than a direct link between the two indicators.
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.
