The Demographic Transition Model uses birth

and death rates to determine where countries fall along the Developing Developed spectrum

As countries develop economically they will progress further along to the next stage

As countries develop overtime, birth and death rates will go from high to low suggesting an increased internal development

What the “DTM” is?

Ahh the Stages!CBR, CDR, and NIR

3. Birth rates decline well after death rates. (Why?)

1. What causes birth rates to drop at this point?

2. Why is the population low at stage 1?

4. What do you think this area is showing?

Let’s break it down!

From 10,000 B.C.E. - 1750 C.E. every person,

empire, or country was here

Hunter Gatherer tribes were among this stage

High birth rates/death rates

Pop. growth very slow

Early Agrarian (Agriculture) societies were here

Threatened by high rates of contagious disease or famine

Many children needed for farming

Today, no country today is in this

Stage 1

5. Why does it fluctuate?

Stage 1 Pics

Great Britain was the 1st country to

enter stage 2 with the Industrial Revolution (Late 1750's-> Early 1800's)

Death rates declined (Basic hygiene and medicine introduced)

NIR (Natural Increase Rate) increases sharply

High Population growth from decrease in deaths

Improvements in food supply, agriculture, technology, and medical understanding drop rates

Stage 2

Basic Sanitation to the country

Stage 2 Pics

Known as the later Industrial stage

(Starts around 1900’s)

Birth rates decline sharply

Death rates decline slowly (More advanced tech and med.)

Pop. Growth occurs, but slowly

Urban migration increases

Female literacy and family planning increases

Improved contraceptives available

Stage 3

Afghanistan - female: 24.2%(2015)Mexico - female: 94.2% (2012)Portugal - female: 99.7% (2015)

Literacy Rates

"Post Industrial" (Modern Countries)

Birth/Death rates both low

Pop growth low or zero

Life expectancy high (Doctors highly available & tech. advanced)

More equal rights for women

Smaller family size

Developed Countries)

Stage 4

Stage 5??• Your country is so advanced that birth

rates decline to a point where it is lower than the death rate

• Population is declining overtime

• 6. Why is this bad for a country???• 7. Why is family size declining at this

stage???
