Net reproductive rate of 1 can be achieved if Couple production rate is more than:
Demographers are of the view that a net reproductive rate of 1 can be achieved if couple protection rate (CPR) is > 60%. CPR is based on observation that 50-60% of bihs in a year are of bih order 3 or more. Thus attaining a CPR of 60% or more will be equivalent to cutting off almost all third or higher order bihs leaving 2 or less children per couple or net reproductive rate around 1.
