Population density is lower in the highlands than in the western lowlands. Although the majority of the population—60.2%—is between 15 and 64 years of age, Lesotho has a substantial youth population numbering around 34.8%.
Ethnic groups and languages
Lesotho's ethno-linguistic structure consists almost entirely of the Basotho, a Bantu-speaking people: an estimate of 99.7% of the people identify as Basotho. Basotho subgroups include the Bakuena (Kuena), Batloung (the Tlou), Baphuthi (the Phuti), Bafokeng, Bataung (the Tau), Batšoeneng (the Tšoene), Matebele, etc.
The main language, Sesotho (or Sotho), is also the first official and administrative language, and it is what Basotho speak on an ordinary basis. English is the other official and administrative language.
