The number of deaths occurring among the population of a given geographical area during a given year, per 1,000 population, represents a fundamental measure of mortality. For instance, if a region with a population of 100,000 experiences 800 deaths in a year, the resulting value would be 8.0 per 1,000 population.
This metric offers a straightforward snapshot of mortality levels within a population and provides a basis for comparison across different regions or time periods. Its simplicity makes it readily understandable and allows for preliminary assessments of public health conditions. Historically, it has served as a vital tool for tracking demographic changes and identifying potential health crises.
