Editor's note: The woman who has been found alive in the rubble of a residential building in Nairobi, Kenya, is one of an estimated 80 people missing since it suddenly collapsed Friday amid heavy flooding, killing 33. It's possible she may not be the last to survive the tragedy: a woman was rescued 17 days after the 2013 Rana Plaza factory collapse in Bangladesh, and there have been similar stories of survival in the aftermath of the 2007 Haiti earthquake, among others. - Tricia
Nairobi (/naɪˈroʊbi/; locally [naɪˈroːbi]) is the capital and largest city of Kenya. It is famous for having the Nairobi National Park, the world’s only game reserve found within a major city. The city and its surrounding area also form Nairobi County, whose current governor is Evans Kidero.
The name "Nairobi" comes from the Maasai phrase Enkare Nairobi, which translates to "cool water". The phrase is also the Maasai name of the Nairobi river, which in turn lent its name to the city. However, it is popularly known as the "Green City in the Sun", and is surrounded by several expanding villa suburbs.
Nairobi was founded in 1899 by the colonial authorities in British East Africa, as a rail depot on the Uganda Railway. The town quickly grew to replace Machakos as the capital of Kenya in 1907. After independence in 1963, Nairobi became the capital of the Republic of Kenya. During Kenya's colonial period, the city became a centre for the colony's coffee, tea and sisal industry. The city lies on the River Athi in the southern part of the country, and has an elevation of 1,795 metres (5,889 ft) above sea level.
With a population of about 3.36 million estimated in 2011, Nairobi is the second-largest city by population in the African Great Lakes region after Dar es Salaam, Tanzania. According to the 2009 census, in the administrative area of Nairobi, 3,138,295 inhabitants lived within 696 km2 (269 sq mi). Nairobi is the 14th-largest city in Africa, including the population of its suburbs.
Nairobi is one of the most prominent cities in Africa, both politically and financially. Home to thousands of Kenyan businesses and over 100 major international companies and organisations, including the United Nations Environment Programme (UNEP) and the United Nations Office at Nairobi (UNON), Nairobi is an established hub for business and culture. The Nairobi Securities Exchange (NSE) is one of the largest in Africa and the second-oldest exchange on the continent. It is Africa's fourth-largest exchange in terms of trading volume, capable of making 10 million trades a day.
