Nairobi is one of the top cities in sub-Saharan Africa for expatriates to live and work in according to a study released by human resources consultant Mercer in early April. The Kenyan capital ranks sixth out of 30 in the Mercer Business Quality of Living survey, behind Cape Town and Johannesburg in South Africa, Lusaka (Zambia), Dakar (Senegal) and Blantyre (Malawi), but ahead of its regional neighbours Dar es Salaam (Tanzania), Khartoum (Sudan) and Addis Ababa (Ethiopia). Nearly 40 criteria including political, environmental, social and economic factors as well as personal safety and public services are taken into account when ranking cities.

Nairobi is up one place against last year, although it falls short of making it into the top 100 cities worldwide. Only two cities in Africa Cape Town and Johannesburg appear on this list, which is topped by Zurich and Geneva in Switzerland.
