Answer
Proportionate mortality measures the percentage of all deaths in a given population that are attributed to a specific cause. It is calculated by dividing the number of deaths from the specific cause by the total number of deaths from all causes, and then multiplying by . In this scenario, there were deaths from chronic liver disease and total deaths from all causes. The calculation is . This epidemiological metric is highly useful for health departments to identify the leading causes of death and prioritize public health resources, although it does not measure the risk of dying from the disease for a healthy member of the general population.
