The Demographic Transition A life altering educational experience.
The Demographic Transition is a process with several stages, explaining how a country transitions from a LDC to a MDC.
Stage 1 - Low Growth • High CBR – have 6 kids so 3 can survive. • High CDR – famine, disease, animal attacks. • Low or Zero NIR • Low or Zero Growth • This was the stage for most of human history. • From the Agricultural Revolution to the Industrial Revolution, the population did grow (5 million to 800 million), but stayed at Stage 1.
Stage 2 – High Growth • High CBR – traditional large families, religion, poor women’s rights, etc • Low CDR, it is dropping suddenly. The Industrial and Medical Revolutions contributed to this. • High Growth • High NIR • Population grew 10 x’s faster than the past. Why? • Industrial Revolution18th Century – Improved diet, transportation/preservation of foods, fresh fruits and veggies, sanitation, fresh water. • Medical Revolution 20th Century –After WWII LDCs were introduced to medicine, vaccines, and vitamins saving many lives.
Stage 3 – Moderate Growth • Dropping CBR • Slowly dropping CDR • NIR is dropping slowly • The country is in the process of changing from an LDC to a MDC. • Why the drop in CBR? • Changes in social customs – religion, women’s rights & jobs • Infant survival and smaller families, not farmers anymore. • World is becoming more urban/modern.
Stage 4 – Low Growth • Low CBR • Low CDR • Low NIR • Why do MDC’s have close to Zero Population Growth? • Social Customs, women working, contraceptives, kids are expensive. • Adults choose to do other things than have kids.
