What might link these
The strong correlation between GVA and manufacturing value added per unit of GDP may indicate that countries with a strong manufacturing sector tend to have higher overall economic output. However, a careful reader should be cautious about assuming causation, as other factors such as technological advancements or trade policies could be driving this relationship. A likely confounder is the level of industrialization in each country.
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 causal link between manufacturing and overall economic output, when in fact other underlying factors may be at play.
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.
