Thomas Malthus
       • 1798:    Essay on the Principle
         of Population as it Affects the
         Future Improvement of
         Society
          – Population growth tends
             to outstrip the means of
             subsistence
          – Food increases
             arithmetically while
             population increases
             geometrically
          – The poor can be kept alive
             by charity, but since they
             would then propagate,
             this is cruelty in disguise.
Paul Ehrlich
      • 1968: The Population
        Bomb

      • “The battle to feed all of
        humanity is over.
      • In the 1970s the world
        will undergo famines—
      • Hundreds of millions of
        people are going to starve
        to death”

Demographic Transition
               • First, high birth
                 rates and high
                 death rates
               • Then, improved
                 living standards,
                 health cause death
                 rates to drop
               • Finally, low birth
                 rates match low
                 death rates
Demographic Transition
           • 1750-1950: Occurred in
             developed countries
           • 1950: Began to see death
             rates drop in developing
             countries
           • 2050: Projected
             completion of transition
Demographic Transition

                • Example: U.S.
                 History
                  – When agrarian
                    society, people
                    had many kids
                     • Source of
                       security, labor
Demographic Transition
               • Example: U.S.
                 History
                 – When became
                   industrial, fewer
                   kids/family
                     • Lowered infant
                       mortality
                     • No need to rely on
                       children’s labor
                     • More opportunities
                       for women
                     • Happened without
                       birth control
Global Fertility
              • 1950’s:   5
                children/woman
              • 1970’s: 4
                children/woman
              • 1990’s: 2.8
                children/woman
              • Replacement: 2.1
                children/woman
Global Population
         • Population growth rate is
           slowing down and will
           eventually stop
         • Dip in 1960 due to 30
           million deaths in China
            – Great Leap Forward
              Famine
World Population Projection
• Estimated to peak at 11 billion in 2200

AIDS
                      • 40 million people infected
                        with HIV
                         – Many will die of AIDS
                      • Will not greatly impact
                        global population growth
                      • Will Impact some countries
                      • Losses by 2020:
                         – Uganda 45%
                         – Rwanda 35%

Food Production per Capita
             • Food Production per
               capita is rising
               worldwide
                – But falling in Africa
             • Food production is
               keeping up with
               population
                – Otherwise food prices
                  would have risen
                – Food prices have dropped
Food Production in Sub-Saharan
           Africa

               • Food Production in
                 Sub Saharan Africa

Progressivist View
               • Things are good and getting
                 better:
                  –   Worldwide standard of living
                  –   Education
                  –   Health
                  –   Trade
               • People are an asset.
               • Population causes shortages
                 which raise prices,
                  – stimulating entrepreneurs to
                    satisfy the shortages.
               • We end up better off as a
Julian Simon     result.
Progressivist View

         • Two important
           indicators of progress
           and improvement in
           life are
           – Decreased Infant
             Mortality
           – Increased Life
             Expectancy

Revisionist View
                           • Adoption and spread of agriculture
                             have trapped humanity in a spiral of
                              – Population growth
                              – Ecological destruction
                              – Social tyranny.
                           • The problem stems from the
                             anti-ecological culture (religion)
                             of agricultural societies
                              – humans are above and not part of
                                nature (global ecosystem)
                              – and therefore can destroy it at will.
Civilization is based on
Agriculture
Daniel Quinn
 • 1992: Ishmael
    – Although population is 5.5 billion, we
      produce enough food for 6.0 billion even
      though millions are starving
    – Because we produce enough food for 6
      billion, in 3 or 4 years there will be 6
      billion people.
    – Then, even though millions are starving,
      we will produce enough for 6.5 billion.
    – Thus in another 3-4 years there will be
      6.5 billion
    – To halt this process, must face the fact
      that increasing food production doesn’t
      feed the hungry, it only fuels the
      population explosion.
Social Equity View
                                                                        • Problems of

                                                                          – overpopulation
                                                                          – ecological destruction
                                                                        • Are due to

Both hunger and high fertility
          occur when:
                    • Poverty is extreme and
                        widespread
                    •   Society denies security and
                        opportunity to people
                    •   Infant mortality is high
                    •   Most people can’t get land,
                        jobs, education, health care, old
                        age security
                    •   Few opportunities for women
                        outside of home

Children

      • Labor force
      • Chance for a job in city
      • Security
           – major investment
           – rational choice
Women’s Education

         • Powerful predictor of
           lower fertility
         • Reflects opportunity in
           society
Male Poverty


      • Low self-esteem
      • Dominate women and
        children
      • Thus more children
Examples
                 • Sri Lanka:
                     – lower price rice
                          • led to population decline
                 •   Cuba:
                      – low prices for food and health care
                         • reduced population rate from 4.7 to 1.6

                 • Kerala, India:
                     – lower price rice, kerosene
                         • 1/3 birth rate of average in India
                         • Literacy for women is 2.5 times
                           average in India

Family Planning
                     • Birth Control is responsible for only
                       15-20% total fertility decline
                        – Thus population growth cannot be
                          brought down simply by family planning
                          or contraception
                        – but it can speed the decline
                     • Contraceptive use in Developing World
                       has increased
                        – 9% in 1960
                        – 60% in late 1990s

Device                 improved
                        – Health
                        – Social Security
                        – Education
Sterilization
                      • Encouraged by Western
                        donors for developing
                        countries
                         – Quotas are set
                         – Incentives are used
                             • Cash, roads, transportation,
                               latrines
                             • For hungry, choices are
                               limited
                      • 1/3 of married women in
                        India and China are sterilized

             • U. S. seized in 1898
             • Sugar companies set up vast
                 plantations
             •   Small farmers evicted
             •   By 1925, 2% of population
                 owned 80% of land, 70% of
                 population landless’
             •   Unemployment termed
                 “overpopulation” by U.S.
             •   By 1940’s light
                 manufacturing moved in
                 attracted to cheap labor, low
                 taxes
Puerto Rico: La Operacion
        • Young women were key to labor force
        • Problem was pregnancy
        • Result: massive sterilization program
        • Women coerced into sterilization
          without being told it was irreversible
        • By 1968, 1/3 of women childbearing
          age were sterilized.
        • Emigration and sterilization resulted in
          population drop with no increase in
          standard of living.

     • Cost was very high:
       $120/birth averted
        – This is 120% of per capita
          gross domestic product
        – Not replicable on a national

Fertility decline in China
China One Child Policy
          • 1979 “one child” policy enacted
             – For urban areas
          • Material benefits
             – if have 1 child
          • Social & official pressure
             – If have more than 1 child
          • 71% Chinese are rural
             – Multiple children are common
          • Fertility rate has declined
             – But also declined in other Asian
               countries without coersion
          • Human rights violation?
Birth Control Methods in China
Skewed sex ratio
        • Sex ratio at birth (2000)
           – 117:100 male:female
              • Maternal Hepatitus B may
                  account for much of the skewing
        • Boys preferred
           – Men care for parents in old age
           – Women join husband’s family
              • Care for husband’s parents
        • Selective abortion of girls
           – Use ultrasound to determine sex
           – If first child is a girl, want second
             to be a boy
           – Illegal but suspected
        • Female infanticide suspected
           – before ultrasound

Population

  • 1. Population Sources: The World Food Problem Leathers and Foster, 2004 World Hunger 12 Myths Lappe Collins and Rossett, 1998 Hesketh et al., New England J. Med 353: 1171-1176 Wikipedia http://www.lastfirst.net/images/product/R004548.jpg
  • 2. Thomas Malthus • 1798: Essay on the Principle of Population as it Affects the Future Improvement of Society – Population growth tends to outstrip the means of subsistence – Food increases arithmetically while population increases geometrically – The poor can be kept alive by charity, but since they would then propagate, this is cruelty in disguise.
  • 3. Paul Ehrlich • 1968: The Population Bomb • “The battle to feed all of humanity is over. • In the 1970s the world will undergo famines— • Hundreds of millions of people are going to starve to death”
  • 7. Demographic Transition • First, high birth rates and high death rates • Then, improved living standards, health cause death rates to drop • Finally, low birth rates match low death rates
  • 8. Demographic Transition • 1750-1950: Occurred in developed countries • 1950: Began to see death rates drop in developing countries • 2050: Projected completion of transition
  • 9. Demographic Transition • Example: U.S. History – When agrarian society, people had many kids • Source of security, labor
  • 10. Demographic Transition • Example: U.S. History – When became industrial, fewer kids/family • Lowered infant mortality • No need to rely on children’s labor • More opportunities for women • Happened without birth control
  • 11.
  • 12.
  • 13. Global Fertility • 1950’s: 5 children/woman • 1970’s: 4 children/woman • 1990’s: 2.8 children/woman • Replacement: 2.1 children/woman
  • 14. Global Population • Population growth rate is slowing down and will eventually stop • Dip in 1960 due to 30 million deaths in China – Great Leap Forward Famine
  • 15. World Population Projection • Estimated to peak at 11 billion in 2200
  • 17. AIDS • 40 million people infected with HIV – Many will die of AIDS • Will not greatly impact global population growth • Will Impact some countries • Losses by 2020: – Uganda 45% – Rwanda 35% – Malawi 30% Malawi AIDS orphans
  • 19. Food Production per Capita • Food Production per capita is rising worldwide – But falling in Africa • Food production is keeping up with population – Otherwise food prices would have risen – Food prices have dropped
  • 20. Food Production in Sub-Saharan Africa • Food Production in Sub Saharan Africa not keeping up with population
  • 21. Per Capita Production of Calories, Fat, Protein
  • 22. Progressivist View • Things are good and getting better: – Worldwide standard of living – Education – Health – Trade • People are an asset. • Population causes shortages which raise prices, – stimulating entrepreneurs to satisfy the shortages. • We end up better off as a Julian Simon result.
  • 23. Progressivist View • Two important indicators of progress and improvement in life are – Decreased Infant Mortality – Increased Life Expectancy
  • 25. Revisionist View • Adoption and spread of agriculture have trapped humanity in a spiral of – Population growth – Ecological destruction – Social tyranny. • The problem stems from the anti-ecological culture (religion) of agricultural societies – humans are above and not part of nature (global ecosystem) – and therefore can destroy it at will. Civilization is based on Agriculture
  • 26. Daniel Quinn • 1992: Ishmael – Although population is 5.5 billion, we produce enough food for 6.0 billion even though millions are starving – Because we produce enough food for 6 billion, in 3 or 4 years there will be 6 billion people. – Then, even though millions are starving, we will produce enough for 6.5 billion. – Thus in another 3-4 years there will be 6.5 billion – To halt this process, must face the fact that increasing food production doesn’t feed the hungry, it only fuels the population explosion.
  • 27. Social Equity View • Problems of – poverty – overpopulation – ecological destruction • Are due to – inequity of wealth – unfairness of economic and social systems Frances Moore Lappe, Food First http://www.mediathatmattersfest.org/mtm05/img/frances_moore_lappe.jpg
  • 28. If the world were 100 people (2005) • 51 male – 49 female • 60 Asians, – 14 Africans, – 12 Europeans, – 8 Latin Americans, – 5 from USA and Canada – 1 from the South Pacific • 82 nonwhite – 18 white • 67 non-Christian – 33 be Christian (Source: Family Care Foundation)
  • 29. If the world were 100 people (2005) • 80 live in substandard housing • 67 unable to read • 50 malnourished – 1 dying of starvation • 33 without access to safe water supply • 39 lack access to improved sanitation • 24 have no electricity – Most of the 76 with electricity use it only for light at night (Source: Family Care Foundation)
  • 30. If the world were 100 people (2005) • 7 have access to the internet • 1 has a college education • 1 has HIV • 2 near birth – 1 near death • 5 control 32% of the entire world’s wealth – All 5 U.S. citizens • 33 attempt to live on 3% of global income (Source: Family Care Foundation)
  • 31. Both hunger and high fertility occur when: • Poverty is extreme and widespread • Society denies security and opportunity to people • Infant mortality is high • Most people can’t get land, jobs, education, health care, old age security • Few opportunities for women outside of home Bangladesh mother
  • 32. Children • Labor force • Chance for a job in city • Security – major investment – rational choice
  • 33. Women’s Education • Powerful predictor of lower fertility • Reflects opportunity in society
  • 34. Male Poverty • Low self-esteem • Dominate women and children • Thus more children
  • 35. Examples • Sri Lanka: – lower price rice • led to population decline • Cuba: – low prices for food and health care • reduced population rate from 4.7 to 1.6 • Kerala, India: – lower price rice, kerosene • 1/3 birth rate of average in India • Literacy for women is 2.5 times average in India Kerala, India
  • 36. Family Planning • Birth Control is responsible for only 15-20% total fertility decline – Thus population growth cannot be brought down simply by family planning or contraception – but it can speed the decline • Contraceptive use in Developing World has increased – 9% in 1960 – 60% in late 1990s IUD: Intra Uterine • Demographic Transition requires Device improved – Health – Social Security – Education
  • 37. Sterilization • Encouraged by Western donors for developing countries – Quotas are set – Incentives are used • Cash, roads, transportation, latrines • For hungry, choices are limited • 1/3 of married women in India and China are sterilized Indian woman
  • 38. Puerto Rico: La Operacion • U. S. seized in 1898 • Sugar companies set up vast plantations • Small farmers evicted • By 1925, 2% of population owned 80% of land, 70% of population landless’ • Unemployment termed “overpopulation” by U.S. • By 1940’s light manufacturing moved in attracted to cheap labor, low taxes
  • 39. Puerto Rico: La Operacion • Young women were key to labor force • Problem was pregnancy • Result: massive sterilization program • Women coerced into sterilization without being told it was irreversible • By 1968, 1/3 of women childbearing age were sterilized. • Emigration and sterilization resulted in population drop with no increase in standard of living.
  • 40. Bangladesh • Intensive Family Planning in Matlab region • Contraceptive use doubled • Resulted in reduced birth rate • Cost was very high: $120/birth averted – This is 120% of per capita gross domestic product – Not replicable on a national scale
  • 41. China • 1950s, 60s Under Mao – children encouraged – Fertility rate: 5.9 children/woman • 1970-1979 new policy to cope with overpopulation – “one is good, 2 is ok, 3 is too many” – “late, long, few” • Have fewer children later • greater spacing between • Fertility dropped steeply to 2.9 http://news.bbc.co.uk/1/shared/spl/hi/asia_pac/02/china_party_co ngress/china_ruling_party/key_people_events/html/default.stm
  • 43. China One Child Policy • 1979 “one child” policy enacted – For urban areas • Material benefits – if have 1 child • Social & official pressure – If have more than 1 child • 71% Chinese are rural – Multiple children are common • Fertility rate has declined – But also declined in other Asian countries without coersion • Human rights violation?
  • 45. Skewed sex ratio • Sex ratio at birth (2000) – 117:100 male:female • Maternal Hepatitus B may account for much of the skewing • Boys preferred – Men care for parents in old age – Women join husband’s family • Care for husband’s parents • Selective abortion of girls – Use ultrasound to determine sex – If first child is a girl, want second to be a boy – Illegal but suspected • Female infanticide suspected – before ultrasound
