What might link these
Indicator A, 'Age population, age 00, female, interpolated,' likely refers to the proportion or count of very young females (potentially around age 0) in the total population. Indicator B, 'Population ages 0-14, female,' is a broader measure of young females. The strong correlation suggests that countries with a higher proportion of very young females also tend to have a higher proportion of females in the broader 0-14 age bracket. While not a direct restatement, they are very closely related demographic concepts.
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 strong correlation might arise because both indicators are fundamentally measuring the same underlying demographic phenomenon: the presence of young females in a population, making the relationship less surprising than it might initially appear.
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.
