what are the 5 stages of demographic cycle
- high stationary stage CBR-high CDR-high
- early expanding stage high. starts declining
- late expanding stage. starts declining. already dec
- low stationary stage low low
- declining stage. CDR>CBR (JAPAN)
what stage of demographic cycle india is in

1 TFR(total fertility rate)
- GRR(gross reproductive rate)
- NRR(net reproductive rate)
what is TRF(total fertility rate)
total no of children born to a female
what is GRR(gross reproductive rate)
total no of girl children born to a female
what is NRR(net reproduction rate)
total no of girl children born to a female (mortality is taken into account)
what is completed family size
TFR(total fertility rate)
formula of CBR with respect to TFR
CBR= (8TFR)+1
