↵† Proportions for causes of death do not sum to 100% because some data were suppressed, as a result of small cell sizes.
↵‡ Metabolic causes of death included metabolic, nutritional, immunity and endocrine conditions, as well as diseases of the digestive system.
↵§ Accidental causes of death included motor vehicle crashes, accidental poisoning, falls, fire, and drugs or adverse events in therapeutic use.
