New Karu and Koroduma are villages that grew, as a result of the rapid growth and expansion of administrative and economic activities of Abuja into neighbouring towns, coupled with the evacuation of tens of thousands of people from Abuja by the Federal Capital Territory (Nigeria) (FCT) administration. Mararaba is believed to be one of the most densely populated suburbs around the Nigerian capital city Abuja and this contributes to its reputation as having one of the busiest road channels with traffic jams stretching as much as 11 kilometers from the popular A.Y.A. junction during rush hours. Mararaba also has various markets e.g. mararaba market etc.[1]
The indigenes of Mararaba are the Hausa/Fulani people.
