What term describes the number of deaths per 1000 people per year?

The term that accurately describes the number of deaths per 1000 people per year is known as the mortality rate. This figure is a key demographic indicator that provides insight into the health of a population and can reflect various factors such as healthcare quality, living conditions, and social stability. By measuring mortality in relation to the total population, it allows for standardized comparison across different regions and time periods.

The concept of death rates is often used interchangeably with mortality rates in some contexts, but typically refers to the general category of rates at which deaths occur. In contrast, life expectancy refers to the average number of years a person can expect to live based on current mortality trends and conditions. Demographic transition is a theoretical model that explains the transition from high birth and death rates to lower birth and death rates as a country develops, rather than focusing on the specific statistics of mortality itself.
