Epidemiology of anencephaly in a suburban Nigerian agrarian community in the rain forest: An 11-year retrospective study of a single hospital experience

•The epidemiology of anencephaly has not been documented in our suburban agrarian community.•A retrospective review of the labour ward register over eleven year period from 2007 to 2017 was carried out.•There were 5 cases of anencephaly out of the 3, 789 deliveries over the eleven year period resulting in 1.3 per 1000 deliveries.•There is, therefore, need for a well-designed prospective study to corroborate these findings.
