Question

For the Net Reproduction Rate (NRR) to be equal to 1, the couple protection rate should be at least?

• A. 50%
• B. 60%
• C. 55%
• D. 75%

Hint:

Replacement-level fertility (NRR=1) needs CPR just above the 60% mark.

Answer 1

The Correct Option is B

Step 1: Understand the concept. Couple Protection Rate (CPR) is an indicator of the prevalence of contraceptive practice in the community. It is defined as the percentage of eligible couples effectively protected against childbirth by one or other approved methods of family planning, such as sterilization, IUD, condom or oral contraceptive pills (OCPs).
Step 2: Link CPR to NRR. The Net Reproduction Rate of 1 means each woman is exactly replacing herself with one daughter in the next generation, indicating that the population has reached replacement-level fertility.
Step 3: Apply the demographic target. An NRR of 1 can be achieved only when CPR is greater than 60%. Hence the couple protection rate should be 60%, making option (b) correct.
Step 4: Why distractors are wrong. 50% and 55% are below the threshold required to stabilise the population at replacement level, and 75% is higher than the minimum required value being asked.
