# 001 - Population Change - Part One

## Syllabus Point

Explain (AO2) population trends and patterns in births (Crude Birth Rate), natural increase and mortality (Crude Death Rate, infant and child mortality rates), fertility and life expectancy in contrasting regions of the world.

## Key Terminology

• Explain
• Trend
• Pattern
• Crude Birth Rate
• Crude Death Rate
• Infant Mortality Rate
• Child Mortality Rate
• Natural Increase in Population
• Fertility Rate
• Life Expectancy
• Population Momentum

Define the words above using the 'Command Term' posters in the classroom and the links below.

## Activity One - Describe and Explain

1. Using the graph below describe the changes in world population.
2. Using the resources below explain why these changes have taken place. You can also use your 'Geography Course Companion' by Nagle and Cooke.
3. Why can data be misleading?

## Activity Two - Notes

Using the 'Population, Resources and Development' text book by Crispin and Jegede page 47, answer the following questions:

1. Make notes on crude death rates (remember to include the equations).
2. Why can this measurement be misleading? Give examples
3. What are 'Age Specific Death Rate', 'Age and Sex Specific Death Rates'? How are they measured? (Equations)
4. Define and explain the factors that affect 'Maternal Mortality Rate'.
5. Using figure 3.25 on page 50, examine the factors that affected death rates in the UK between 1700 and 1950.
6. What factors impact fertility rates, death rates and life expectancy? Remember to explain your answers. (Pages 3,4,7 and 9 in the 'Geography Course Companion' will help you as well as the links below).

Remember to give values for a range of countries where possible. It is vital you understand what is a high or low figure. You should also be able to give examples!!!

## Activity Three - Research

Choose three countries at differing levels of development. Describe the changes in overall population of these countries and then explain why the population levels have changed. (Hint - you could use the USA, Morocco and Ethiopia below or choose your own.).

## Extra Notes

Watch the YouTube clip above and make notes on the changes in population, why they happen and the misconceptions that people have.

## Exam Style Question
