What might link these
The correlation might be driven by factors like family planning and social welfare policies, which influence both birth rates and consumer spending. A careful reader should consider education level as a potential confounder. The relationship could be nuanced and context-dependent.
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 female birth rates and household expenditure, when in fact other factors like cultural and economic development may 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.
