  • 1. Birth rate Death rate Immigration Emigration What about what’s in the bath? What does this bath represent?!?
  • 2. Population Change <ul><li>ALL population change is the result of natural change or migration </li></ul><ul><li>During the next few weeks we will study the different factors that affect natural change, and the causes and consequences of migration. </li></ul>
  • 3. Key Definitions <ul><li>Birth Rate </li></ul><ul><li>‘ the number of births per 1000 people per year’ </li></ul><ul><li>Death Rate </li></ul><ul><li>‘ the number of deaths per 1000 people per year’ </li></ul><ul><li>Natural Change </li></ul><ul><li>‘ the difference between the birth rate and death rate. It tells you by how much the population is changing per 1000 people each year’ </li></ul><ul><li>Migration </li></ul><ul><li>‘ the movement of people from one area to another’ </li></ul>
  • 5. Population Change <ul><li>What do we know? </li></ul><ul><ul><li>Population has grown rapidly in the last 200 years </li></ul></ul><ul><ul><li>Levelled off a little, but still expanding by 80million a year </li></ul></ul><ul><ul><li>By 2050, population will be 9billion </li></ul></ul><ul><ul><li>By end of the century, it may be 0%growth </li></ul></ul>
  • 6. Population Change <ul><li>What do we know? </li></ul><ul><ul><li>The growth within the world is not even </li></ul></ul><ul><ul><li>Europe, N.America and Australasia have very low growth rates </li></ul></ul><ul><ul><ul><li>Only 20% of world’s population, by 2050 this will be 12% </li></ul></ul></ul><ul><ul><li>Europe’s population will shrink by 90million between now and 2050 </li></ul></ul><ul><ul><li>In that period, China India and Pakistan will contribute most to global growth </li></ul></ul>
  • 7. Worldwide Population
  • 8. What Causes Population Change?
  • 10. Demographic Transition Model
  • 11. DTM <ul><li>The Demographic Transition Model shows the changes in a country’s population over time </li></ul><ul><li>It gives information on birth and death rates </li></ul><ul><li>It has five stages </li></ul>
  • 12. DTM <ul><li>Stage One </li></ul><ul><ul><li>High, fluctuating </li></ul></ul><ul><li>Stage Two </li></ul><ul><ul><li>Early expanding </li></ul></ul><ul><li>Stage Three </li></ul><ul><ul><li>Late expanding </li></ul></ul><ul><li>Stage Four </li></ul><ul><ul><li>Low, fluctuating </li></ul></ul><ul><li>Stage Five </li></ul><ul><ul><li>Fluctuating/declining </li></ul></ul>
  • 13. Demographic Transition Model
  • 14. DTM <ul><li>It was based on Britain’s development, and some other industrialised countries, in the 19 th and 20 th Centuries </li></ul><ul><li>They had gone through several ‘stages’ during their development </li></ul><ul><li>It was found that other countries went through the same change </li></ul>
  • 15. DTM <ul><li>STRENGTHS </li></ul><ul><ul><li>Shows change over time </li></ul></ul><ul><ul><li>Can be related to the UK </li></ul></ul><ul><ul><li>Easy to understand </li></ul></ul><ul><ul><li>Puts events into a sequence, and helps to explain the changes </li></ul></ul><ul><li>WEAKNESSES </li></ul><ul><ul><li>Not as relevant for non-industrialising countries </li></ul></ul><ul><ul><li>Doesn’t include migration </li></ul></ul><ul><ul><li>Countries hit by HIV/Aids have gone back to stage one, so harder to predict their futures </li></ul></ul><ul><ul><li>Original model has had to be adapted to include 5 th stage </li></ul></ul>
  • 16. DTM <ul><li>One good way to remember the countries at each stage – ABCD! </li></ul><ul><li>A = Afghanistan </li></ul><ul><li>B = Bolivia </li></ul><ul><li>C = China </li></ul><ul><li>D = Denmark </li></ul><ul><li>E = Erm, Germany (Ein, Zwei, Drei?!?) </li></ul>
