BABY-O-MATIC
Guaranteed 100% accuracy
1. Discuss your score with your group
2. Discuss how many children you actually believe you will have
3. Using your ‘Sherlock’ Inferencing Skills – determine what factors will affect the number of children a woman may have in her lifetime.

Historical Population What was the world’s population in 1804?
1 billion What happened in China in 1979? One Child
Policy Examine the world’s population in 1927, 1960,
1974, 1987, 1999 ~ what trend do you notice? Exponential (fast) population growth
Examine the world’s population in 2013, 2028, 2054, 2200 ~ what trend do you notice about projections? Rate of Population Growth is decreasing - (natural increase)
Historical Population Growth
United Nations Population Models
Measuring Population Change
Population change is measured by four basic components:
How many people are born – BIRTH RATE
How many people die – DEATH RATE How many move into an area –
IMMIGRATION RATE How many move out of a region (EXIT)
– EMIGRATION RATE
NATURAL INCREASE
NI = BIRTH RATE – DEATH RATE • Canada’s Natural Increase: 10.6 – 7.4 = 3.2 per
1000
(STABLE/CONTRACTING) Russia’s Natural Increase: 10.8 – 15.1 =
-4.3
(CONTRACTING) India’s Natural Increase: 23.0 - 8.5 = 14.5

Canada’s Population Density
World’s Largest Cities
1. Tokyo – 37 m
2. Jakarta – 26m
3. Seoul – 22m
4. Dehli
5. Shanghai – 20m
10. Mexico – 19m
POPULATION FACTSThe world’s population growth pattern has been exponential; it is increasing at a rapid pace that can seem uncontrollable at times.
Why the explosion in population growth?
•The number of people (death rate) is decreasing due to better medical care
•Birth rates continue to be high in COUNTRIES THAT STRUGGLE WITH POVERTY however in many newly industrializing countries like India, infant mortality is decreasing.
But Surprise!
The world’s population growth rate is decreasing on every continent. We reached our peak growth rate around 1950, and our rate of natural increase is decreasing globally.
CANADIAN STATS
Overall Population Density is extremely low
Average Life Expectancy is 81 years oldBC – Men 80, Women 84
Rate of Natural Increase is 4.0 (2013) Population growth rate is highest of all
G8 countries – 2/3 of growth rate is from immigration – important to support aging population of BABY BOOMERS
Why would people want a large family?
BRAINSTORM
Why Do Some Countries Have Large Populations and Other Small?
Career Prospects Birth rates Death Rates Health Care ‘Need for Children’ – poverty Education levels Women’s Rights Infant Mortality Rate Rural living – more workers needed to collect water, etc. Sons bring wealth, dowries, etc. Sense of community
AGE THAT WOMEN HAVE THEIR FIRST CHILD IS EXTREMELY SIGNIFICANT - LONGER PROLONGED, LOWER POPULATION RATES
The Demographic Transition Model
(CP pg 324)
A theory that explains how populations will change. According to this theory, a population will pass through 5 stages.
Age Pyramid Review – Early Expanding
CONCAVE SHAPEHigh Birth RatesHigh Death RatesPopulations are not
extremely high because of death rates
Short life expectancy Congo (51),
Afghanistan (61), Sierra Leone (48)
Age Pyramid Review – Expanding
Typical PYRAMID shape
High Birth Rates Death Rates are
starting to lower – increased health care
Generally large populations
Slightly longer life expectancies
India, Mexico
Age Pyramid Review – Stable
Often looks like a ‘house’ Relatively straight sides Birth rates significantly
lower Death Rates significantly
lower – strong health care
Much larger elderly population
Population can sustain itself
USA, France
Age Pyramid Review – Contracting
Bottom is extremely small
Very low birth rate Low death rate Large population of
elderly people Needs immigration to
sustain its population with labour force
Japan, Germany, Canada
Prediction Questions Which pyramid type has a “shrinking” population?
CONTRACTING Which pyramid type has the highest birth and death
rates? EARLY EXPANDING Which pyramids do you think have the highest standard of
living? STABLE/CONTRACTING Which pyramid do you think is most likely to represent
Brazil or India? EXPANDING Which pyramid do you think represents Afghanistan or
Congo? EARLY EXPANDING Which pyramid has the largest number of people under
15, and people over 64? EXPANDING DEPENDENCY RATIO – MOST PEOPLE TO TAKE CARE OF

What makes populations shift through different stages?
Now match it up to Pyramids…*** This is a spectrum..with space in between different stages
What Does Your Pyramid Look Like? Be prepared to explain your pyramid to
me! Include at least 5 age cohorts….
