Age-Specific Fertility Rate is expressed per 1,000 women to:
A. Align with mortality rate conventions
B. Simplify calculation
C. Match the scale of Crude Birth Rate
D. Avoid small decimal values and facilitate comparison
Answer: Option D
Solution (By JKSSB Mock Tests)
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:
Subtracting P(A ∩ B) corrects for the fact that outcomes in the intersection are counted twice when adding P(A) and P(B), ensuring accurate probability calculation for the union.
