The calculation of injury rates involves the following steps:
1. Identify the numerator: The total number of injury cases within the specified period. 2. Identify the denominator: The population at risk during the same period. 3. Rate formula: (Number of injuries / Population at risk) × Multiplier (e.g., 100,000).
For example, if there were 500 injuries in a city with a population of 100,000 over one year, the injury rate would be (500/100,000) × 100,000 = 500 injuries per 100,000 population annually.
