g) Describe the global trend in Birth Rates from 1960 to 2015. You must include data in your answer.


2) Death Rates



a) Name countries with the three highest Death Rates. Include the data in your answer.

b) Name countries with the three lowest Death Rates. Include the data in your answer.

c) Which regions of the world have the lowest Death Rates. Give named examples of countries and their birth rates.

d) Which regions of the world have the highest Death rates. Give named examples of countries and their birth rates.




e) Use the graph above to describe the global trend in Death Rates from 1960 to 2015. You must include data in your answer.


3) Understanding the link between Birth Rate and Death Rate

a) Is there a link between the countries with high birth rates and high death rates? Give examples of countries with both high birth rates and high death rates.

b) Do countries with low birth rates also have low death rates? Give examples to support your answer.

c) Are there any countries which don't fit the pattern, for examples a country with a high death rate and low birth rate or vis-versa.

d) Do you think it is easier to lower the birth rate or the death rate in a Less Developed Country? Explain your answer.



Extension Task:

World at 7 Billion Banner.PNG

a) What's your number? click here. to find out. Use the calculator to find out where you fit in the 7 billion people on the planet. Take a screen shot of your number and insert it into your notes.

b) Read the articles and watch the videos on "How Many more?," "Seven Stories," "Population control," and "Is seven billion accurate?" from the same BBC website. Make notes on each section.


How many more will there be?

c) Watch the video below and be able to explain why there are different predictions on population change .

Task 6: Population Structure


Aims:

To know what a population pyramid is and what information it shows.

To be able to interpret a population pyramid

To understand how population pyramids can reflect development.


1) Before we start lets recap on some vocabulary. Download a copy of the population definitions document and add the definitions that you have learned from Tasks 1-5.


2) Now add definitions for the terms LEDC/ELDC and MEDC/EMDC using the information on this geographyalltheway.com page.

3) Read the definitions below and then add them to your vocab list.




Definitions:

Fertility rate: The average number of children a female is expected to have in their lifetime.

Infant mortality: The number of deaths before the age of 1, per 1000 live births per year.

Life expectancy: The average age that someone is expected to live within a country. Generally women tend to live a few years longer than men.



Population Pyramids

4) Carefully read through the PowerPoint below and make notes in your book. The information you need to answer the following questions can be found in the PowerPoint so make sure you read it from start to finish.

What do you think this graph tells us about Switzerland?

5) Save a copy of the Swiss Population Pyramid document to your documents. Once you have done this open it and label the population pyramids of Switzerland with the terms, young dependents, elderly dependents and economically active.

6) Add the definitions of young dependent, elderly dependent and economically active to your definitions sheet.




Definitions:

Population Pyramid: A population pyramid shows the age and sex structure of the country. It is a type of graph that is divided into males and females and then age groups.

Young Dependents: The number or the percentage of the population under the age of 16.

Old Dependents: The number or the percentage of the population over the age of 65.

Economically Active: People between the ages of 16 and 65. This is basically the working group.

Dependency Ratio: The ratio between the amount of dependents (old and young) and the economically active.

Why do we classify the elderly as, "Old Dependents?"

Note:

Obviously some people stay at school past the age of 16, some people retire before 65 and some people work after 65. Also some people between 16 and 65 might unemployed. However, when we are look at entire populations we have to look at averages (the norm).



7) Click here to go the population structure exercise on geographyalltheway.com.

Complete the population pyramids worksheet below using the information on the web page.


8) Go back to the Power Point you worked on in question 4. Use your knowledge of population pyramids to label the population pyramids for Switzerland (2015 and 2050), India and Uganda. What do the pyramids tell us about the population structure of the three countries.

Boys at school in Uganda. How might Uganda's population growth change if more girls were to attend school?


9) Here you can find population pyramids for every country in the world. Use this link to find the predicted population pyramids for India and Uganda in 2050. Insert them into the Power Point and add labels to them highlighting the key information about the population structure and change for each country as you did for question 8.


Extension:

10) What problems do you think the governments of Switzerland, India and Uganda will face in 2050. Think about the relative sizes of the Young, Elderly and Economically Active Groups. Write a paragraph under the relevant slide in the PowerPoint you have made.

India will be the most populous country in the world by 2022. Why? What impact will this have on the country?


11) Click on the image above and make notes on the article. You could create an info graphic to illustrate the facts given.


12) Read the article below. Add extra rows to your definitions sheet and include definitions for Foeticide and Infanticide.

"India's missing girls: fears grow over rising levels of foeticide."

Skewed gender ratio caused by killing of thousands of girls has given rise to a system of bride-buying and trafficking





Task 7: Carrying Capacity


How many more can the earth support?


How many people could the earth's resources support? What is the 'carrying capacity of the earth?


Carrying capacity is not a fixed number.

Estimates put Earth's carrying capacity at anywhere between 2 billion and 40 billion people.

If humans were still in the hunter-gatherer mode, Earth would have reached its capacity at about 100 million people.

If everyone on Earth lived like a middle-class American, consuming roughly 3.3 times the subsistence level of food and about 250 times the subsistence level of clean water, the Earth could only support about 2 billion people.

If everyone on the planet consumed only what he or she needed, 40 billion would be a feasible number.
