A process of change in society’s population from high crude birth and death rates and low rate of natural increase to a condition of low crude birth and death rates, low rate of natural increase, and higher total population
Demographic transition: Stage 1
Very high CBR, Very high CDR, very low NIR
Demographic transition: Stage 2
Still high CBR, rapidly declining CDR, very high NIR, usually has a relatively high percentage of young people
Demographic transition: Stage 3
Rapidly declining CBR, moderately declining CDR, moderate NIR
Demographic transition: Stage 4
Very low CBR, Low, slightly increasing CDR, 0 or negative NIR, usually has a relatively high percentage of elderly people
