In Sudan's 2008 census, the population of northern, western and eastern Sudan was recorded to be over 30 million. This puts present estimates of the population of Sudan after the secession of South Sudan at a little over 30 million people. This is a significant increase over the past two decades, as the 1983 census put the total population of Sudan, including present-day South Sudan, at 21.6 million. The population of Greater Khartoum (including Khartoum, Omdurman, and Khartoum North) is growing rapidly and was recorded to be 5.2 million.
