Which term describes the number of deaths per 1000 of population per year of a specific age group?

The term that describes the number of deaths per 1,000 individuals within a specific age group is known as the age-specific death rate. This metric is crucial for demographers and public health officials, as it provides insights into mortality trends and health outcomes for particular segments of the population. By focusing on specific age groups, this rate allows for a more detailed understanding of where health interventions may be necessary, as different age groups often experience varied health challenges.

This contrasts with broader terms like mortality rate, which may encompass the entire population without specifying age. Life expectancy, on the other hand, pertains to the average number of years a person is expected to live based on current mortality trends, and does not directly measure deaths per 1,000 individuals. Population density illustrates the number of people living per unit area and is unrelated to mortality figures. Each of these alternative terms serves distinct purposes in demography and public health, but when specifically addressing the death rate within a particular age category, age-specific death rate is the accurate terminology.
