What might link these
The relationship between the growth rate of females aged 55-59 and the percentage of the population aged 0-14 might be influenced by broader demographic trends, such as changes in fertility rates or aging populations. A careful reader should consider the potential impact of urbanization, which could affect both indicators. Urbanization could be a confounder here, as it often correlates with lower birth rates and an aging population.
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 relationship between these age groups, when in fact they may both be responding to underlying demographic shifts.
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.
