Age-Specific Fertility Rate is expressed per 1,000 women to:
A. Simplify calculation
B. Match the scale of Crude Birth Rate
C. Avoid small decimal values and facilitate comparison
D. Align with mortality rate conventions
Answer: Option C
Solution (By JKExamLibrary)
Using a base of 1,000 converts rates to whole numbers (e.g., 120 instead of 0.12), enhancing readability and comparability across age groups and populations without changing the underlying proportion.
Explanation:
Direct standardization applies the study population's age-specific death rates to a standard age structure to compute a hypothetical crude rate, enabling comparison free from age composition effects.
