The mortality rate is a measure of the frequency of death in a defined population over a specific period. It is often expressed as the number of deaths per a certain number of people, commonly per 100,000 individuals, to allow for easier comparison between populations of different sizes. Calculating the mortality rate helps public health officials, researchers, and policymakers understand health trends, identify risk factors, and evaluate the effectiveness of interventions.
