Objective To study the long-term trend of the epidemiological characteristics and death rate of nongupu residents who died from injuries. Methods The demographic data and death data of the 1990s in Ningxia Disease Surveillance System were used. The time trend of mortality was analyzed by linear regression statistical model. Results The mortality rate of residents in Ningxia increased by 28.2% over the 10-year period, and the cause of all-cause death rose to No. 3. The top four cause of injury deaths in 1999 were traffic accidents, suicide, drowning and poisoning. The mortality rate The trends are different. The total injury fatality rate, traffic fatal accident rate and suicide mortality rate are on the rise. The mortality rate of drowning is on the decline.
