Question

Standardized death rates are particularly useful for:

• A. Comparing death rates of males and females
• B. Comparing death rates at different ages among women only
• C. Comparing death rates of two regions
• D. Comparing death rates of two female populations of two different age groups

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.

Answer 1

The Correct Option is C

Step 1: Consider two regions, Region 1 and Region 2, with different proportions of elderly people. Region 1 having an older population will show a higher crude death rate than Region 2 even if people of the same age in both regions face identical mortality risk.
Step 2: To make a fair comparison, we apply a single standard population's age distribution as weights to both regions' age specific death rates. This gives the standardized death rate for each region.
Step 3: Any difference that remains between the two standardized rates now reflects a genuine difference in mortality experience, not a difference caused by unequal age structures.
Step 4: This is precisely why standardized rates are used to compare death rates between two regions (or any populations with differing compositions).
\[ \boxed{\text{Comparing death rates of two regions}} \]
