What might link these
Rapid urbanization might signal increased domestic production and self-sufficiency, reducing reliance on imports. Alternatively, countries with fast-growing urban populations may face infrastructure and resource constraints that limit import capacity.
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 observed negative correlation might be influenced by underlying development stages, where both rapid urbanization and import patterns are shaped by a country's overall economic trajectory.
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.
