Gross reproduction rate is the sum of birth rates by 5-year age groups multiplied by five and by the proportion of births that were female. Net reproduction rate is the sum of birth rates by 5-year age groups multiplied by five, and by the probability of women surviving to a specified age group Gross Reproduction Rate: Notes GRR, like TFR, assumes that the hypothetical cohort of women pass from birth through their reproductive life without experiencing mortality. This assumption is satisfactory when one wants to compare levels of fertility and/or gross reproduction across populations and over time. Total fertility rate (TFR), gross reproduction rate (GRR), net reproduction rate (NRR), reproduction survival ratio (RSR), mean age of childbearing (MAC) and mean length of generation (MLG) are actually the measures of reproductivity. These reproduction rates have been computed only from current vital statistics or any indirect technique. The net rate of reproduction (NRR) is fraction of kids that will be girls, which in this case is half. NRR = (2)*(1/2)=1 (b) Now women will live with certainty till age 30. Gross Reproduction Rate (GRR): Measure of population replacementIndicates the number of daughters of a hypotheticalcohort of women by the end of the reproductive lifeif she bears the births according to a given schedule ofage-specific fertility rates( taking only female births)without experiencing any mortality till the end ofreproductive life .

Gross reproduction rate measures the rate at which a new born female would, on an average, add to the total female population, if they remained alive and experienced the age specific fertility rate till the end of the child bearing period. It is the sum of fertility rate till the end of the child bearing period.

The gross reproduction rate (GRR) is the average number of daughters a woman would have if she survived all of her childbearing years, which is roughly to the age of 45, subject to the age-specific fertility rate and sex ratio at birth throughout that period. This rate is a measure of replacement fertility if mortality is not in the equation.

If a (fictional) generation of 100 women were supposed not to be subject to the effect of mortality and were to have, at each age (between 15 and 50) the fertility observed in year n, then these 100 women would give birth in the course of their lives to a number of girls which is, by definition, the gross reproduction rate (for year n).

The net reproduction rate, R 0, is the average number of daughters that would be born to a female (or a group of females) if she passed through her lifetime conforming to the age-specific fertility and mortality rates of a given year. This rate is similar to the gross reproduction rate but takes into account The gross reproduction rate (GRR) is the average number of daughters a woman would have if she survived all of her childbearing years, which is roughly to the age of 45, subject to the age-specific fertility rate and sex ratio at birth throughout that period. This rate is a measure of replacement fertility if mortality is not in the equation. Gross reproduction rate measures the rate at which a new born female would, on an average, add to the total female population, if they remained alive and experienced the age specific fertility rate till the end of the child bearing period. It is the sum of fertility rate till the end of the child bearing period. If a (fictional) generation of 100 women were supposed not to be subject to the effect of mortality and were to have, at each age (between 15 and 50) the fertility observed in year n, then these 100 women would give birth in the course of their lives to a number of girls which is, by definition, the gross reproduction rate (for year n). The gross reproduction rate relates the fertility rate to female births only. It is defined as the number of girls which are expected to be born to 1000 females passing through their child bearing years. The gross reproduction rate is calculated from the total fertility rate in the following manner: Gross Reproduction Rate (GPR) = x Total fertility rate.

The gross reproduction rate (GRR) is the average number of daughters a woman would have if she survived all of her childbearing years, which is roughly to the age of 45, subject to the age-specific fertility rate and sex ratio at birth throughout that period. This rate is a measure of replacement fertility if mortality is not in the equation. This allows one to define the two-sex gross reproduction rate or, equivalently, the two-sex total fertility rate 2STFR. Measures for human reproduction should be linked to both men and women (*) The United Nations refers to countries as "developed" that had a gross reproduction rate of less than two in 1963. Gross reproduction rate (GRR) is the average number of daughters that would be born to a woman during her lifetime if she passed through her child-bearing years conforming to the age-specific fertility rates (ASFR) of a given year. GRR is measured exactly like TFR except that it counts only daughters and measures “reproduction” – a woman reproducing herself in the next generation by having a daughter.
