Transcript

  • 1. Objectives: •Identify the main differences between MEDC’s and LEDC’s using population data and population pyramids.
  • 2. Characteristic Definition Birth Rate (BR) Death Rate (DR) Natural Increase Stage in DTM (Demographic Transition Model) Population Structure Line graphs showing relationship between birth and death rate through time. Live births per 1000 people per year Make up of a population by age and sex, shown by population pyramids Population growth when BR is higher than DR. Replaced by natural decrease when BR is lower Deaths per 1000 people per year
  • 3. Characteristic Definition MEDC’s Birth Rate (BR) Live births per 1000 people per year Death Rate (DR) Deaths per 1000 people per year Natural Increase Population growth when BR is higher than DR. Replaced by natural decrease when BR is lower Stage in DTM (Demographic Transition Model) Line graphs showing relationship between birth and death rate through time. Population Structure Make up of a population by age and sex, shown by population pyramids Low % under age 15 (below 25%) Low or non- existent; can be a minus value 4 or 5 (Stage 5 when DR is higher than BR) Low (typical value 8-15) Low average (9- 10)
  • 4. Characteristic Definition MEDC’s LEDC’s Birth Rate (BR) Live births per 1000 people per year Low (typical values 8-15) Death Rate (DR) Deaths per 1000 people per year Low (average 9-10) Natural Increase Population growth when BR is higher than DR. Replaced by natural decrease when BR is lower Low or non- existent; can be a minus value Stage in DTM (Demographic Transition Model) Line graphs showing relationship between birth and death rate through time. 4 or 5 (Stage 5 when DR is higher than BR) Population Structure Make up of a population by age and sex, shown by population pyramids Low % under age 15 (below 25%) 2 or 3 (Stage 2 when Natural Increase is large High (typical values 20- 55) High % under age 15 (30- 55%) Low (average 9-10) High
  • 5. Characteristic Definition MEDC’s LEDC’s Birth Rate (BR) Live births per 1000 people per year Low (typical values 8-15) High (typical values Death Rate (DR) Deaths per 1000 people per year Low (average 9-10) Low (average 9-10) Natural Increase Population growth when BR is higher than DR. Replaced by natural decrease when BR is lower Low or non- existent; can be a minus value High Stage in DTM (Demographic Transition Model) Line graphs showing relationship between birth and death rate through time. 4 or 5 (Stage 5 when DR is higher than BR) 2 or 3 (Stage 2 when Natural Increase is large) Population Structure Make up of a population by age and sex, shown by population pyramids Low % under age 15 (below 25%) High % under age 15 (30 – 50%)
  • 6. Describe the differences and similarities between MEDC’s and LEDC’s from the table of information you have produced.
  • 7. Tasks Use the population pyramids of Germany and Pakistan to answer the following questions. 1. How many people are there aged under 15 in (i) Gemany (ii) Pakistan 2. How many people are there aged over 64 in (i) Germany (ii) Pakistan 3. How many people are there of working age (20-60) in (i) Germany (ii) Pakistan
  • 8. As identified previously, MEDc’s and LEDC’s often have dramatically different birth rates, but why is this? Children can be seen as an economic cost that reduces the amount of money left for purchasing consumer goods and services. Women are more career orientated. They now work for longer and start families later in life. Children seen as an economic asset. They can provide an income for families. Lack of money to be spent on family planning and education about family planning
  • 9. A fall in a country’s birth rate usually accompanies an increase in national and personal wealth. The national government has more funds to promote birth control campaigns and to set up family-planning clinics. With greater wealth, attitudes to children change, as identified previously in the differences between MEDC’s and LEDC’s. Lowering the birth rate allows movement to stage 3 of the DTM. If this continues then transition to stage 4 will occur. This is where most European countries are at.
  • 10. Birth Rate per 1000 GDP per capita (US$) UK 9 24000 Canada 9 23000 Australia 12 19000 Saudi Arabia 34 8500 Russia 8 4500 China 14 1000 Brazil 19 2500 Peru 23 2000 Algeria 24 1500 Bangladesh 30 700 Mali 49 200 Niger 55 100 Plot the information from the table onto a scatter graph. X axis = birth rate Y axis = GDP per capita
  • 11. Answer the following questions 1. What type of correlation is displayed on your graph? 2. Describe the results produced on the graph? 3. There are 3 anomalies on the graph. Can you identify them? 4. Explain why these anomalies exist.
