Median age of population in American Samoa

The median age is the age that divides the population into two numerically equal groups: half the population is younger and half is older.
As a primary metric for demographic aging, the median age provides a high-level summary of an economy's structural maturity, influenced by the long-term interplay of fertility rates, life expectancy, and migratory patterns. A rising median age typically indicates a "graying" population, often driven by declining birth rates and improvements in healthcare that extend longevity.
Unlike simple averages, which can be skewed by small groups of very young or very old individuals, the median offers a more stable reflection of the typical resident’s age.
