Provide definitions for crude birth rates, crude death rates, age-specific fertility rates, and age-specific mortality rates. Explain why it is important to measure age-specific versus crude rates and when one measure might be used instead of another.
What will be an ideal response?
Ans: Varies. Crude birth rates: the number of births each year per 1,000 people. Age-specific fertility rates: the number of births typical for women of a specific age in a particular population. Crude death rates: the number of deaths each year per 1,000 people. Age-specific mortality rates: estimates of the number of deaths typical in men and women of specific ages in a particular population. Although crude rates give a good overall picture of births and deaths, age-specific rates are more useful in estimating future trends.
