According to the CIA, estimates for this country explicitly take into account the effects of mortality because of AIDS; this can result in lower life expectancy, higher infant mortality and death rates, lower population and growth rates, and changes in the distribution of population by age and sex, than would otherwise be expected.
Kenya's economy is the largest in eastern and central Africa, with Nairobi serving as a major regional commercial hub. Agriculture is the largest sector; tea and coffee are traditional cash crops, while fresh flowers are a fast-growing export. The service industry is also a major economic driver, particularly tourism. Kenya is a member of the East African Community trade bloc, though some international trade organisations categorise it as part of the Greater Horn of Africa. Africa is Kenya's largest export market, followed by the European Union.
The Republic of Kenya is named after Mount Kenya. The earliest recorded version of the modern name was written by German explorer Johann Ludwig Krapf in the 19th century. While travelling with a Kamba caravan led by the legendary long distance trader Chief Kivoi, Krapf spotted the mountain peak and asked what it was called. Kivoi told him "Kĩ-Nyaa" or "Kĩĩma- Kĩĩnyaa" probably because the pattern of black rock and white snow on its peaks reminded them of the feathers of the cock ostrich. The Agikuyu, who inhabit the slopes of Mt. Kenya, call it Kĩrĩma Kĩrĩnyaga in Kikuyu, while the Embu call it "Kirenyaa." All three names have the same meaning.
Ludwig Krapf recorded the name as both Kenia and Kegnia. Others say that this was—on the contrary—a very precise notation of a correct African pronunciation ə/. An 1882 map drawn by Joseph Thompsons, a Scottish geologist and naturalist, indicated Mt. Kenya as Mt. Kenia, 1862. The mountain's name was accepted, pars pro toto, as the name of the country. It did not come into widespread official use during the early colonial period, when the country was instead referred to as the East African Protectorate. It was changed to the Colony of Kenya in 1920.
