1. How do population pyramids help us learn about population?

2. POPULATION GROWTH ENCARTA VIDEO CLIP

3. Population pyramids are used to show information about the age and gender of people in a specific country. MaleFemale Population in millions In this country there is a high Birth Rate There is also a high Death Rate. This population pyramid is typical of countries in poorer parts of the world (LEDCs.)

4. In some LEDCs the government is encouraging couples to have smaller families. This means the birth rate has fallen.

5. MaleFemale Population in millions In this country the number of people in each age group is about the same. The largest category of people were born about 40 years ago. In this country there is a low Birth Rate and a low Death Rate. This population pyramid is typical of countries in the richer parts of the world (MEDCs.)

6. Population in millions MaleFemale In this country the birth rate is decreasing. In the future the elderly people will make up the largest section of the population in this country. This is happening more and more in many of the world’s richer countries.

7. Male Female Population in thousands This country has a large number of temporary workers. These are people who migrate here especially to find a job.

15. File path - Student pool/Geography/Year 9/Population/Pyramids Your task: Open your own PowerPoint presentation. Go to www.census.gov www.census.govwww.census.gov Select Search and type in IDB. Select International Database From here select Population Pyramids. Find a population pyramid typical of a poor country (LEDC) copy and paste it into your PowerPoint document then add labels to explain what is shown. Repeat for an MEDC (rich) country. For a country of your choice copy and paste the pyramids for 2000, 2025 and 2050. Write about what the graphs show and try to give reasons for the patterns. Explain how the population of this country is changing and say how that could affect the country.

17. When you have finished; Find out some background information on each country and add this to your presentation. Concentrate on facts and figures which you can use to compare the countries such as % of the children at school, type of jobs available, how rich or poor (GDP per capita.)………

20. Levels of Population The Three Levels of Population 1 – Under Population This describes the situation where there are more resources in an area than the population needs. In most respects this is a good situation, as populations can stockpile resources or sell / donate resources, but it can mean resources are underused.

21. Levels of Population The Three Levels of Population 2 – Optimum Population When an area is at optimum population, it has exactly the right amount of resources to support its population. There are no problems with the population gaining access to the resources they need, nor are there problems with resources being underused.

22. Levels of Population The Three Levels of Population 3 – Overpopulation When an area is overpopulated, it means that there are not enough resources to support the population. This may be because there are too many people or not enough resources. This can cause immense difficulties for the people in that area.
