Khartoum North
In Sudan's 1993 census, the population was calculated at 30 million. No comprehensive census has been carried out since that time due to the Second Sudanese Civil War. Estimates of Sudan, including the population of South Sudan, ranged from 37 million (United Nations) to 45 million (CIA). Since the secession of South Sudan in July 2011, the current population of Sudan is estimated to be about million. The population of metropolitan Khartoum (including Khartoum, Omdurman, and Khartoum North) is growing rapidly and ranges from six to seven million, including around two million displaced persons from the southern war zone, as well as western and eastern drought-affected areas.
