This question checks the three time bound goals written into the National Population Policy 2000.
- 2005: No target of the policy is fixed at this year.
- 2010: This is the year the policy names for bringing the total fertility rate to replacement level, which is the same as a net reproduction rate of 1.
- 2015: This year does not appear as one of the three stated goals.
- 2050: This is later than the long term goal, which is a stable population by 2045.
The policy sets an immediate goal on contraceptive needs, a medium term goal of replacement level fertility, that is NRR equal to 1, by 2010, and a long term goal of a stable population by 2045. So the correct year for NRR of 1 is 2010.
Let's summarize:
- NRR of 1 is another way of stating replacement level fertility.
- NPP 2000 fixed 2010 as the year for this medium term goal, and 2045 for the long term stable population goal.
So the correct answer is 2010.
