were higher for persons 75–84 years and 85 years of age and over, at 116 and 281 per 100,000 persons.
Injury death rates were higher for males than for females in each age group except for infancy when the rates were similar. In 1995 for children 1–9 years of age, injury death rates for males were about 1.5 times the rates for females, and the difference increases with age. The mortality sex ratio (the ratio of death rate for males to that for females) jumped from 2.1:1 at ages 10–14 years to 4.6:1 at 20–24 years. The mortality sex ratio for persons 65 years and over was about 2:1.
Injury death rates vary with race and ethnicity. The average annual injury death rate for 1993–1995 among teenagers and young adults 15–34 years of age was higher for the black population and for American Indian/Alaskan Natives (referred to as American Indians) (119 per 100,000) than for Hispanics (78 per 100,000), non-Hispanic white population (58.0 per 100,000), and Asian or Pacific Islanders (referred to as Asians) (36 per 100,000). Unintentional injury death rates and suicide rates were higher for American Indians than for other racial and ethnic groups. Homicide rates were higher for the black population than for other groups. Motor vehicle traffic injuries were the leading cause of unintentional injury in each race and ethnic group.
In 1993–1994, 9 percent of all discharges had a first-listed injury diagnosis. For persons 25 years and over, 7–9 percent of discharges were for an injury. Differences by sex were greater for persons ages 15–24 years (31 percent among males compared with 4 percent among females) and for persons 25–44 years of age (17 percent for males compared with 5 percent for females) than for other ages (Figure 2.5). For both white and black males 15–44 years, 20 percent of all hospital discharges were for an injury compared with about 5 percent among females.
The age and gender patterns for injury-related hospitalization are different than those for mortality. In general, discharge rates for persons with a first-listed diagnosis of injury increase with age. In 1993–1994 the average annual rates for children under 5 years of age and 5–14 years of age were 57 percent and 42 percent of the rate for young persons ages 15–24 years (90 discharges per 10,000 persons), and that rate is about one-half the rate for persons 65–74 years of age, and about a fifth of the rate for persons 75 years of age and over (412 per 10,000 persons).
Although injury discharge rates for males and females were similar (108 and 99 per 10,000 persons) for all ages combined, gender discharge rates vary considerably by age. At ages 15–24 years the discharge rates for males were twice those for females (119 compared with 60 per 10,000), whereas for the elderly 75 years of age and over, the rate for males was about 70 percent of the rate for females (322 compared with 463 per 10,000 persons).
