Nety Production:
N.R.R = (i) \(\sum_{i=15}^{49} \) W.S.F.R x S
Where i – age width, S-Survival Rates.
W.S.F.R = \(\frac {\textit{Female births}}{\textit{Female population}} \) x 1000
W.S.F.R X S(15 – 19) = 25 x 0.96 = 24
Similarly calculate for other age groups
Σ W.S.F.R x S = 596.62
∴ M.R.R = 5 x 596.62
= 2983.09 Female births occur per 1000 women of (15 = 49) years.
N.R.R. per women
= \(\frac{N.R.R}{1000}\) = \(\frac{2983.09}{1000}\) = 2.983
Female Children bom per women. Here the N.R.R. per women is more than one. Therefore, the population increases. [Because the mother will be replaced by daughters so that fertility will be continued].
