To achieve a NRR of 1, Couple protection rate should be: March 2005

Ans. D: More than 60% Couple protection rate is an indicator of the prevalence of contraceptive practice in the community. It is defined as the percent of eligible couples effectively protected against childbih by one or the other approved methods of family planning. CPR is based on the observation that 50-60% of bihs in a year are of bih order 3 or more. Thus attaining a 60% CPR will be equivalent to cutting off almost all third or higher order bihs, leaving 2 or less surviving children per couple So demographic goal of NRR=1 can only be achieved only if the CPR exceeds 60%.
