In the Third Conference of African Statisticians held in Addis Ababa in 1963, the United Nations Economic Commission for Africa (UNECA) agreed to support the establishment of a training centre in Eastern Africa to serve Kenya, Uganda, and the United Republic of Tanzania. A key meeting held in February 1964 at the headquarters of the East African Common Services Organization (EACSO) in Nairobi, Kenya, recommended Dar es Salaam as the most suitable location for the new centre.
