CBR high, need for child labour and replacement babies
Describe stage 2 of the demographic transition model
CBR= high
CDR= Decreasing
Demographic change is natural increase(youthful population)
Early industrialisation

CDR decline due to; better nutrition, improved healthcare and sanitation
Describe stage 3 of the demographic transition model
CBR= declining
CDR= low
Demographic change: natural increase (young economically active)
Society adjusts to lower mortality, birth rates begin to decline
Continued improvements in medical care
Wider contraceptive use, female education and higher status

Advanced medical services and good quality life
Wide contraceptive accessibility
High female status allows concentration on education/employment
