Question:
Standardized death rates are particularly useful for:
Standardized death rates are particularly useful for:
Show Hint
Standardization removes the confounding effect of differing age composition, making it suitable for comparing mortality across populations with different age structures, such as two regions.

- Comparing death rates of males and females
- Comparing death rates at different ages among women only
- Comparing death rates of two regions
- Comparing death rates of two female populations of two different age groups
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: The crude death rate of a population is a weighted average of its age specific death rates, the weights being the proportion of population in each age group. It therefore depends heavily on the population's own age composition.
Step 2: Two populations can show very different crude death rates purely because one has an older or younger age structure, even when the underlying age specific mortality risks are similar. This makes crude death rates unfair for direct comparison.
Step 3: Standardization (direct or indirect method) fixes one common standard age distribution and applies it to the age specific rates of each population being compared, removing the distorting effect of differing age compositions.
Step 4: This is exactly the situation of comparing mortality of two different regions, which typically differ in age composition. So standardized death rates are particularly useful for comparing death rates of two regions.
Final answer: option (C).
