In this report, firearm-related fatalities are defined according to the ICD* as an underlying cause of death coded as:

Data on the number and characteristics of firearm-related fatalities among Arizona residents were obtained from the death certificates filed with the Arizona Department of Health Services.

Population denominators for Arizona residents, used to calculate rates, are projections from the Population Statistics Unit in the Arizona Department of Economic Security (data for 1985 - 1989 and 1993-1995) and the U.S. Census Bureau (data for 1990). Detailed population data by gender, age and county were unavailable for 1991-1992. In order to obtain the population denominators for these two years, the 1990 percentages of population breakdowns (or census shares) by age group and gender were applied to 1991 and 1992 total state or county population estimates published by the DES.

The aggregation of 1985-1995 data made it possible to increase the reliability of rates by age group, gender and ethnicity. Eleven-year summary rates calculated for the entire period 1985-1995 provide a more accurate description when the number of events is small and/or events occur in small populations.
