Another African country making our list of countries with the highest youth population is Lesotho, where the average age of citizens is 21 years. The youth unemployment rate here was 33% in 2014. Shockingly, this number is higher than the overall unemployment rate in the country which was 26.2% in the same year. Nevertheless, the country expects to create more opportunities for its youngsters in the near future, as its economy is growing steadily.
