This data asset contains the data from the ‘Every Mother and Newborn Counts’ (EMNC) study carried out in Jember District in East Java Province and Serang District in Banten Province by the United States Agency for International Development (USAID) Jalin Project. The districts were selected based on high maternal and neonatal mortality burden and local government commitment following a consultation with the Ministry of Health (MOH) and Provincial Health Offices (PHO). Data was collected in the two districts between December 2018 and April 2019. First, the study team enumerated all eligible maternal and neonatal deaths in the study areas using a proven method for counting these mortality events, known as Maternal Death from Informant/Maternal Death Follow-on Review (MADE-IN/MADE-FOR) and Neonatal Death from Informant/ Neonatal Death Follow-on Review (NODE-IN/NODE-FOR). Once eligibility was confirmed, each household experiencing a maternal or neonatal death was visited by a trained interviewer. The interviewers conducted a ‘verbal and social autopsy’ (VASA) interview with family members or household caregivers of the deceased to determine the likely causes of death and the circumstances surrounding the death. Causes of death were analyzed using the InSilico computer algorithm.
