Crude Birth Rate is expressed per 1,000 population to:
A. Simplify arithmetic
B. Convert the rate to a convenient whole number scale
C. Align with death rate calculation
D. Match international standards
Answer: Option B
Solution (By JKExamLibrary)
Using a base of 1,000 transforms small proportions (e.g., 0.02) into whole numbers (20), enhancing readability and comparability across populations without altering the underlying rate.
Explanation:
Geometric mean correctly averages multiplicative processes (e.g., compound growth rates) by taking the nth root of the product, avoiding bias from arithmetic mean in ratio contexts.
