How is the mortality rate described in population demographics?

The mortality rate in population demographics is defined as the number of deaths occurring in a given population during a specific time period, typically expressed per 1,000 individuals. This rate provides a clear measure of the mortality impact on a population and is crucial for public health assessments, allowing for comparisons between different locations and time periods.

Option B accurately reflects this definition of mortality rate, as it specifically quantifies the deaths per 1,000 population, which is the standard metric used in demographic studies and health statistics. Understanding mortality rates is essential for healthcare planning, resource allocation, and identifying health trends over time.
