gross reproduction rate


Also found in: Wikipedia.

gross re·pro·duc·tion rate

the average number of female children a woman would have if she survived to the end of her childbearing years and if, throughout that period, she were subject to a given set of age-specific fertility rates and a given sex ratio at birth; this rate provides a measure of the replacement fertility of a population in the absence of mortality.
