The Demographic Transition

Vocabulary Crude Death Rate (CDR)—Deaths/1000 people Crude Birth Rate (CBR)—Births/1000 people Natural Increase Rate (NIR) — % a population grows each year

The Demographic Transition

Stage 1 Lasted for thousands of years of human existence Food supplies unpredictable, even after agricultural revolution (when people started farming) Also, a lack of medical knowledge meant diseases killed large numbers of people As a result, birth and death rates fluctuated, no natural increase

Stage 2—The Industrial Revolution 1750ish—Industrial Revolution—New technology and factories allowed for constant food supply Also new advances in medical supplies First happened in Great Britain, spread through Europe and North America Death rate drops big time Natural increase rises

When did the Industrial Revolution Happen? First happened in Europe and North America—1750- early 1800’s Then, happened in Latin America, Africa and Asia in the mid 1900’s Reason—Medical Revolution—Stopped diseases in tropical areas of Latin America and Asia So different parts of the world are in different stages of the transition

Stage 3 When people choose to have fewer children People now live longer, so the population is getting too big More people live in cities (urbanization), so large families no longer helpful However, still some natural increase (birth rate higher than death rate)

Where? Europe and North America were first into stage 3 Asia and Latin America now moving into stage 3 Many African and some Asian countries still in stage 2

Stage 2--Less Developed Countries (LDC’s) 1.What problems (cons) do you think a country with this shape of population pyramid will have? 2. How could this shape of population pyramid actually help a country?

Cons –Youth bulge –High dependency ratio because of huge number of children –Difficult to provide medical care –Difficult to provide education –May lead to high levels of unemployment Pros –Lots of able-bodied workers! –No need for immigrant labor –Young people are creative!

Stage 4—Zero Population Growth Death rate and birth rate are the same Country reaches zero population growth Women work more, (gain more status in society—govt. positions?), have less kids Some European countries in this stage

More Developed Countries (MDC’s) Pros?Cons?

Developed/Stage 4 countries Pros— –More educated workforce –Women pursuing careers and getting high paying jobs –Low youth dependency ratio Cons— –Might not have enough future workers! (immigrants?) –High elderly dependency ratio –Need more medical spending for the elderly
