Mention and explain the measure of mortality and state its merit and demerits.

Answer 1

Mortality rate is a measure of the number of deaths in a population over a given period of time. It is usually expressed as the number of deaths per 1,000 people per year.

The merit of mortality rate is that it provides a measure of the overall health of a population. It can be used to compare the health of different populations and to track changes in health over time.

The demerit of mortality rate is that it does not take into account the age of the population. For example, a population with a high mortality rate may have a large number of elderly people, which would skew the results. Additionally, mortality rate does not take into account the cause of death, which can be important in understanding the health of a population.
