A net reproduction rate equal to one can be achieved by the:

Appeared in: DSSSB 6 September 2024

Explanation

The Net Reproduction Rate (NRR) is a key indicator of population replacement. An NRR of 1 means that each generation of women is having just enough daughters to replace itself.
To achieve an NRR of 1, which corresponds to a Total Fertility Rate (TFR) of about 2.1, a significant portion of the reproductive-age population must use contraception.
Demographers and public health experts estimate that a Couple Protection Rate (CPR) exceeding 60% is the threshold required to reach this goal of population stabilization.

Option A: A Couple Protection Rate of over 20% is too low to achieve replacement-level fertility. This rate would still result in significant population growth.
Option B: A Couple Protection Rate of over 10% indicates very minimal use of family planning and would be associated with high fertility rates and rapid population increase.
Option C: A Couple Protection Rate of over 40% shows moderate adoption of family planning but is insufficient to bring the NRR down to 1. Population growth would continue, although at a reduced rate.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Relationship between Couple Protection Rate (CPR) and Net Reproduction Rate (NRR) as background academic context rather than a clinical decision trigger.
Understanding the CPR target is crucial for community health nurses involved in implementing and evaluating family welfare programs.
This knowledge helps in setting realistic goals for health workers (like ANMs and ASHA workers) for counseling and service delivery related to contraception.
Achieving a CPR of over 60% is a cornerstone of India's National Population Policy to ensure sustainable development and reduce the burden on health infrastructure.

How to Approach the Question

First, identify the key terms in the question: 'Net Reproduction Rate (NRR) equal to one' and 'Couple Protection Rate (CPR)'.
Recognize that this is a factual recall question from Community Health Nursing or Preventive and Social Medicine.
Recall the definition of NRR=1, which signifies population stabilization or replacement-level fertility.
Access your knowledge of national health program targets. The goal for population stabilization requires a specific level of contraceptive prevalence.
Evaluate the given options. Remember the specific target figure. The widely accepted CPR required to achieve an NRR of 1 is 60%. Select the option that reflects this target.
