What might link these
Wealthier countries may demand more wood products for construction or furniture, while trade infrastructure could facilitate imports. GDP itself was controlled for, but residual economic activity (e.g., construction sector size) might still drive both variables.
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. Correlation does not imply causation; unmeasured factors like urbanization or trade policies could explain the link.
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.
