Despite global reduction, under-5 mortality remains high in most developing countries and tends to
cluster among certain individuals, households and communities. We assess levels and factors influencing
under-5 mortality clustering in a rural setting in northern Nigeria. Data were collected from January
2011 to December 2013 at Nahuche Health and Demographic Surveillance System. Binomial
distribution and Poisson regression model were used to assess family level clustering and factors
associated with under-5 mortality clustering. Results show that there was under-5 mortality clustering,
with 5% of the compounds accounting for 35% of all deaths. Surviving beyond infancy was associated
with reduced incidence rate of under-5 mortality clustering (p<0.05). Child’s age, source of drinking
water and type of provider at delivery during the most recent birth (p<0.05) influenced under-5
mortality clustering. Findings call for evidence-based policies to reduce under-5 mortality.
