Data will be collected by specially trained data collectors. They will collect the data at participants' homes. Participants will include the mother (in case of neonatal death) or next of kin (in case of maternal death) and any additional person who was present during the events that led to the death. Additional interviewees may include the delivered mother's husband, mother, mother-in-law, other family member, neighbor, etc. The delivered mother or next of kin will be asked which individuals, if any, should be included in the interview. The mother or next of kin and the individuals they indicate will be consented individually but interviewed together.
