How are mortality and morbidity best defined?

Mortality is best defined as the death rate within a given population, indicating how many individuals die over a specific period, typically expressed as a number per 1,000 individuals. This measurement provides essential information regarding the overall health and longevity of a population, contributing to public health assessments and resource allocation.

Morbidity, on the other hand, refers to the illness rate within a population. It encompasses the prevalence of disease or injury, measuring how many individuals experience health-related issues that impact their daily lives or well-being. Understanding morbidity helps health professionals evaluate the quality of life within a community and identify areas for health intervention.

This definition captures the distinct yet interrelated concepts of mortality and morbidity, highlighting their significance in public health discussions, research, and planning.
