The global population is aging, with advances in medication, technology, and improved living standards allowing individuals to live longer, more fulfilling lives, raising average life expectancy.
In the U.S., the median age rose from 30 in 1980 to nearly 39 by 2022, while average life expectancy increased from 73.6 to 76.3 during the same period.
Most countries with the youngest populations, including Afghanistan, Ethiopia, and Somalia, face significant challenges including poverty and armed conflict, despite their youthfulness.
Among the identified youngest countries, the age of the average resident ranges from 20.8 to just 15.2, with GDP per capita often below $1,000.
