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.
Practice Cartography is study of: Biology is study of: Volcanology is study of: Seismology is study of: Demography is study of:
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)
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
CENSUS DATA Every 5-10 years in Canada Questions for Canada’s population – gives government information to help provide services Very important Accuracy based on infrastructure, literacy rates, political stability, government freedom, wealth of a country
World’s Largest Cities 1. Tokyo – 37 m 2. Jakarta – 26m 3. Seoul – 22m 4. Dehli 5. Shanghai – 20m 10. Mexico – 19m
POPULATION FACTS The 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 old BC – 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 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 SHAPE High Birth Rates High Death Rates Populations 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…. What are your country’s “prospects for the future”? Ensure is complete ~ worth 5 marks
