World population trends

  1. 1. What patterns exist in world population growth?
  2. 2. <ul><li>Understand how world population has grown; </li></ul><ul><li>Be able to describe and explain future projections; </li></ul><ul><li>Compare and contrast trends in MEDW and LEDW population growth; </li></ul><ul><li>Understand the concepts of over-, under-, and optimum population. </li></ul>What patterns exist in world population growth?
  3. 3. Compare and contrast trends in MEDW and LEDW population growth <ul><li>MEDW </li></ul><ul><li>Population growth slow </li></ul><ul><li>Fertility rate of 2.12 children per woman needed to maintain population (replacement rate) </li></ul><ul><li>UN predicts that by 2016 there will be 88 countries in the ‘Under 2.1 club’ </li></ul><ul><li>Japan spent £50 million on a pro-natalist campaign </li></ul><ul><li>LEDW </li></ul><ul><li>Average growth rate 1.8% </li></ul><ul><li>Birth rates in many countries now in decline </li></ul><ul><li>India expected to catch up with China by 2050 </li></ul><ul><li>However, as these countries become more developed, fertility rates continue to fall </li></ul><ul><li>There is a time-lag between a country reaching replacement level fertility rate & the population falling </li></ul>
  4. 4. Overpopulation <ul><li>Overpopulation exists when there are too many people in an area relative to the amount of resources and the level of technology available to maintain a high standard of living. </li></ul><ul><li>It suggests that if population fell, living standards would rise. </li></ul><ul><li>Characterised by low per capita income, high unemployment and out-migration. </li></ul>
  5. 5. Underpopulation <ul><li>Underpopulation occurs when there are too few people in an area to use resources efficiently for a given level of technology. </li></ul><ul><li>Therefore an increase in population would mean a more effective use of resources and an increase in living standards for all. </li></ul><ul><li>Characterised by high per capita income (but not maximum), low unemployment and in-migration. </li></ul>
  6. 6. Optimum population <ul><li>Optimum population is the theoretical population which, working with all the available resources, will produce the highest standard of living for all people living in that area. </li></ul><ul><li>This concept is dynamic – when technology improves, new resources can be used which means that more people can be supported. </li></ul>
