The normal figure is " net reproduction rate " which is the number of female children a woman will have on average.
3.
This rate is similar to the net reproduction rate but it ignores the fact that some women will die before completing their childbearing years.
4.
The Net Reproduction Rate was then introduced as an alternative measure : it measures the average fertility rate of women of child-bearing ages.
5.
Having a long life expectancy but a low net reproduction rate suggests that the population of gulper sharks would be at a very high risk if too many of them were killed from excessive fishing.
6.
In the absence of migration, a net reproduction rate of more than 1 indicates that the population of females is increasing, while a net reproduction rate less than one ( sub-replacement fertility ) indicates that the population of females is decreasing.
