What this measures

Population ages 0-14 (% of total), in % of population. Source: World Bank. For this measure, no agreed better direction.

The two age shares and the median age are treated as measuring the same thing. Each is a reading of the same age pyramid. So the young share against the old share, at -0.86, is not a finding about anything.

This measure mostly follows how rich a country is, so this ranking is close to a ranking by national income. Each country’s page also ranks it against countries with similar incomes, which is often the fairer comparison.
