3: Comparison of External Cause of Injury Mortality Matrix and the Modified Matrix

Table 1 compares the injury death rates and number of deaths by causes for the External Cause of Injury Mortality Matrix and Modified Matrix.(11,12) Injury death rates for transportation causes differed only slightly when comparing the categorization in two matrices.

Table 2 shows the leading causes of unintentional injury deaths by age group using the External Cause of Injury Mortality Matrix. Suffocation was ranked first for children less than 1 year of age, while MVT-related deaths were first for all other age groups. In order to understand how some subcategories of Transportation-related death rates differ with other causes of unintentional injury, the Modified Matrix is used in all subsequent data presented in this report.

Table 3 shows the leading causes of unintentional injury deaths by age group using the Modified Matrix. Suffocations was still ranked first for infants. However, drowning was the leading cause of death for children 1 to 4, and MVT-Occupant ranked first for the older age groups.
