Gross reproduction rate

Gross reproduction rate

The gross reproduction rate (GRR) is the average number of daughters that would be born to a woman (or a group of women) if she survived at least to the age of 45 and conformed to the age-specific fertility rate of a given year. This rate is similar to the net reproduction rate but it ignores the fact that some women will die before completing their childbearing years.

The GRR is particularly relevant where sex ratios are significantly affected by the use of reproductive technologies.
