Note: The categories listed in this table conform to "Infant Mortality: Development of a Proposed Update to the Dollfus Classification of Infant Deaths" (Nakamura, et. al.), with the exception of certain external causes. Due to the high number of accidental suffocations of infants in bed, the DVRHS lists "Accidents involving suffocation or strangulation in bed" as a separate category.
