8. Honduras
Percentage of youth of total population: 21.6%
Up next on our list of countries with the highest youth population is Honduras, that is a Central American country famous for its beaches. The population of this nation had a median age of 23.4 years in 2015. This is expected to increase to 29.9 years by the time we hit 2030 which means that the percentage of youth will see a sharp decline. However, this average age is still significantly lower than, say, most European countries where it is projected to be somewhere between 45 and 50.
