This dataset contains estimates of maternal and child health (MCH) indicators in Nigeria at the state and national levels. These estimates were produced by the Institute for Health Metrics and Evaluation (IHME) by using multiple data sources and applying complex modeling approaches. Trend estimates in this dataset include under-5 mortality, indicators of childhood nutrition (prevalence of underweight, stunting, and wasting among children under 5), and a range of MCH interventions including malaria control, childhood immunizations, and other key MCH interventions such as skilled birth attendance, exclusive breastfeeding, and prevalence of modern contraceptive use.
