“…A significant number of studies have been carried out on under 5 mortality in Nigeria such as studies by Caldwell and McDonald,1982 ; Ojikutu, 2008 ; Antai, 2011 ; Bamgboye, Clement, Adejuwolo, & Duro, 2012 ; Kayode, Adekanmbi, & Uthman, 2012 ; Akinyemi, Bamgboye, & Ayeni, 2013 ; Izugbara, 2014 ; Abu, Madu, & Ajaero, 2015 ; Chuckwu and Okonkwo, 2015 ; Ezeh, Agho, Dibley, Hall, & Page, 2015 Bako, Maiwada, Abubakar, & Akwo, 2016 ; Adebowale (2017) ; Adewemimo et al (2017) among others. However, these studies are largely determinant studies focused on investigating differentials in and risk factors of under 5 mortality without statistically assessing spatial/geographical patterns of under 5 mortality while the few studies that have done so did not examine spatial clustering across states in Nigeria over time ( Adebayo et al, 2004 , Uthman et al, 2012 ). Nevertheless, spatial pattern analysis is fundamental to understanding and tackling the problem of under 5 mortality.…”
