Gross reproduction rate:
G.R.R = (i) \(\sum_{i=15}^{49} \) W.S.F.R
Where i – Age width
W.S.F.R =\(\frac {\textit{Female births}}{\textit{Female population}} \times100\)
W.S.F.R( 15-19) =\(\frac{80}{100}\) x 1000 = 9.38
Similarly calculate for other age groups.
ΣY W.S.F.R = 180.43; i = Age width = 5
∴ G.R.R = 5 x 180.43 = 902.15
Female births per 1000 women of child bearing age.
No. of Female children born per women
= \(\frac{G.R.R.}{1000}\)
= \(\frac{902.15}{1000}\) = 0.902
Sience this rate. /value is below one, the papulation decreases.
