## Gross rate of reproduction

population, the general fertility rate and the total fertility rate. approximately 1,757 children by the time they would have reached the end of their reproductive.

The gross reproduction rate for the sample area in Calcutta city is therefore 2.34 x 0.49 = 1.15. From this, it is obvious that the gross reproduction rate is essentially a total fertility rate, with the (modification that it is computed only for female births. 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). 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. The gross reproduction rate (GRR) is that the average range of daughters a lady would have if she survived all of her childbearing years, that is roughly to the age of forty five, subject to the age-specific birthrate and sex quantitative relation at birth throughout that amount.

## They can then be used to determine age- or stage-specific fecundity and mortality rates, survivorship, and basic reproductive rates, which in turn can be

The gross reproduction rate (GRR) is that the average range of daughters a lady would have if she survived all of her childbearing years, that is roughly to the age of forty five, subject to the age-specific birthrate and sex quantitative relation at birth throughout that amount. gross reproduction rate is presented by race and Hispanic origin of mother, as is the total fertility rate. To place the rates in context, and to provide an overall indication of the trends over the past four decades, 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. That's what the gross reproduction rate (GRR) does; it calculates the average number of daughters that a woman would have if she lived to age 45. This average is based on the current sex ratios 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. So the previous expression for TFR is. TFR = (1) +(1)+(1/2)+(1/2) = 3 . NRR= 1.5 (c) Now women have half as many kids at each age.

## One of the most basic is the crude birth rate (CBR), the number of live births up a chart of fertility rates across the entire reproductive age and then you assume

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. Gross Reproduction Rate. The gross reproduction rate (GRR) is that the average range of daughters a lady would have if she survived all of her childbearing years, that is roughly to the age of forty five, subject to the age-specific birthrate and sex quantitative relation at birth throughout that amount. Gross reproduction rate. The reproduction of the population refers to a change of a generation into a new one. Reproduction is measured by gross reproduction rates or net reproduction rates that generally indicate the ratio between the sizes of the daughter's and mother's generations. The net reproduction rate (NRR) 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. The gross reproduction rate is calculated from the total fertility rate in the following manner: Gross Reproduction Rate (GPR) = x Total fertility rate. If the number of live births in a year is 25 crore, out of this 12 crore are female births and the total fertility rate is 9.78, then 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. What are Gross reproduction rates. 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.

Gross Reproduction Rate. The gross reproduction rate (GRR) is that the average range of daughters a lady would have if she survived all of her childbearing years, that is roughly to the age of forty five, subject to the age-specific birthrate and sex quantitative relation at birth throughout that amount. gross reproduction rate is presented by race and Hispanic origin of mother, as is the total fertility rate. To place the rates in context, and to provide an overall indication of the trends over the past four decades, 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. That's what the gross reproduction rate (GRR) does; it calculates the average number of daughters that a woman would have if she lived to age 45. This average is based on the current sex ratios 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. So the previous expression for TFR is. TFR = (1) +(1)+(1/2)+(1/2) = 3 . NRR= 1.5 (c) Now women have half as many kids at each age. The net reproductive rate for a set cohort is obtained by multiplying the proportion of females surviving to each age (l x) by the average number of offspring produced at each age (m x) and then adding the products from all the age groups: R 0 = Σl x m x. A net reproductive rate of 1.0 indicates that a population is neither increasing nor decreasing but replacing its numbers exactly.
