What might link these
Both gross fixed capital formation per capita and the proportion of women in older age groups may reflect underlying demographic and economic structures. For example, countries with declining birth rates might see an increasing proportion of older individuals while also focusing investment on different sectors.
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 does not imply that investment decisions are driven by the proportion of women aged 60-64, or vice-versa.
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.
