Population Growth and Change

Measures for population change

Population Structure

Population pyramids

Theories on Variation in Population Growth

Malthus and the Transition Theory

China’s One Child Policy

Kerala, India and Social Justice

slide2

Moscow, Russia

Jaipur, India

slide3

1900=2 billion

1965=3.3 billion

2000=6 billion

2011=7 billion

slide4

Where is

Human

Population

Distributed?

slide5

World Population Cartogram, 1900

Note: the size of Japan’s and China’s populations. Also note the size of Europe’s population—what happens to it over the next 50 years?

slide6

World Population Cartogram, 2000

This cartogram provides a good image of the current distribution of human

population on earth. Are you surprised by the size of the population in any

particular region or country?

slide7

World Population Cartogram, 2050 (projected)

This cartogram illustrates the human population as it will most likely be in 2050. What regions have lost population? Any surprises? Notice what has happened to China’s population since 1900.

another view of the world s population cartogram
Another view of the World’s Population Cartogram
  • This cartogram clearly illustrates which countries have the largest populations. What region of the world clearly dominates in human population numbers? Which regions have the fewest people?
slide10

Where is human population concentrated?

Major Clusters:

East Asia (1/4 of world’s population)

South Asia (1/4 of world’s population)

Europe

Southeast Asia (600 million)

slide11

How is population

density calculated?

Arithmetic Density

Simple calculation of persons/land area

Physiological Density

Explains uneven

distribution of humans across Earth

slide12

Agricultural Density

Reflects differences in economic conditions.

slide16

Crude Birth Rate:

Births per 1,000

Crude Death Rate:

Deaths per 1,000

slide18

Total Fertility Rates (TFR):

average number of children per childbearing years per woman

Niger: 7.16 South Korea: 1.23

Mali: 6.35 Singapore: 0.78

Italy: 1.40

slide22

View the interactive population pyramid for Australia at:

    • http://www.abs.gov.au/websitedbs/d3310114.nsf/home/Population%20Pyramid%20-%20Australia
    • Note the changes for Australia’s population by 2056—what age group will be largest?
  • Or an animated population pyramid for Germany:
    • http://vimeo.com/7687560
    • How has Germany’s population significantly changed since 1950 and what challenges will these changes bring for the country
slide25

What explains variations in population growth?

What is the future of human population growth?

slide28

Demographic Transition Theory:

Stage 1: Low Growth

Stage 2: High Growth

Stage 3: Slowing Growth

Stage 4: Low Growth

slide29

England’s Demographic Transition:

What causes death rates to drop in 1750?

slide34

Why no transition in some countries?

What are the social and economic conditions that lead to large families?

slide37

I CAN’T GET A DATE!!

“As a result, approximately 30 million more men than women will reach

Adulthood and enter China’s mating market by 2020.” CNN

slide38

Fareed Zakaria on China’s “Looming Demographic Catastrophe”

case study kerala india
Case Study: Kerala, India
  • Successful Demographic Transition with the Optimist Approach
    • One of the lowest birth rates in India
    • But a largely agriculturally based society, largely poor and rural
    • Achieved not through strict population policy, but through a program of Social Justice
      • Emphasis on education—for both boys and girls
      • Emphasis on health—lowering the IMR, keeping women healthy
      • Emphasis on rural development—bringing jobs and income to people in rural areas, rather than having families split by migration as one member travels to the nearest city to find work.

case study bangladesh
Case Study: Bangladesh

Muhammed Yunus and the

recipient of a microloan.

  • Bangladesh has not seen much improvement in literacy or wealth
  • However, 56% of women were using contraception in 2011 (just 30 years ago only 6% were)
  • How did this transformation occur? It seems to contradict the traditional explanations for lowering fertility rates.
  • Read about the role of microloans, specifically through the Grameen Bank, in changing women’s financial circumstances:
    • The Grameen Bank: Bank for the Poor
    • Muhammad Yunus, Founder of the Grameen Bank
    • The Economist: Bangladesh & Development
    • New York Times: Bangladesh, Still Poor, Cuts Birth Rate Sharply
