Gross reproduction rate

From Wikipedia, the free encyclopedia

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.^[1] See also total fertility rate and replacement-level fertility.

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