Solution:The Couple Protection Rate (CPR) is the most effective way of reducing the birth rate. An increase in the couple protection rate is most effective if it occurs among younger couples.The Couple Protection Rate (CPR) indicates the percentage of eligible couples who are effectively protected against childbirth by using approved family planning methods. It's a key indicator of contraceptive use and family planning program effectiveness. In India, the CPR is an important aspect of the National Family Planning Programme.
In the context of family planning in India, eligible couples are generally defined as married couples where the wife is within the reproductive age group (typically 15-49 years). CPR includes various contraceptive methods like condoms, pills, IUDs, injectables, sterilization, and others.
A higher CPR generally indicates greater access to and utilization of family planning services, contributing to population stabilization and improved maternal and child health. India has a long-standing National Family Planning Programme aimed at promoting family planning and improving CPR.
