Why has the population grown so quickly?
In small groups discuss this and create a spider diagram with your reason. Do this collaboratively using Coggle. |
Should we be worried?
Population Density and Distribution
optimum populations
Population density: The amount of people living in an area of land.
- Many people in a small area = densely populated
- Few people in a large area = sparsely populated
Population density formula
Optimum population: The population is such that it can maximise the benefits from the resources available. It is only when we have optimum population that the quality of life is maximised.
Over population: The resources cannot sustain the current population. As long as there is over population the quality of life will decline through unemployment, pollution, degradation of the environment.
Under population: The population cannot fully utilise the resources available. Quality of life can only slowly be improved. An increase in population would lead to an increase in quality of life.
Create a table and discuss what areas are likely to be over populated and under populated. Why is this the case?

The Demographic Transition Model
Birth Rate – Number of births, per year, per 1000 people in the population
Death Rate – Number of deaths per year, per 1000 people in the population
Life Expectancy – The average number of years a person at birth can expect to live
Natural Increase - An increase in a country's population because birth-rates are higher than death-rates.
Natural Decrease - A decrease in a country's population because death-rates are higher than birth-rates
Death Rate – Number of deaths per year, per 1000 people in the population
Life Expectancy – The average number of years a person at birth can expect to live
Natural Increase - An increase in a country's population because birth-rates are higher than death-rates.
Natural Decrease - A decrease in a country's population because death-rates are higher than birth-rates

Population Case Studies
For all the case studies below (pages 11-16)
- Locate the country
- Provide factual evidence
- Explain what factors (climate, relief, location, opportunities, natural resources) help cause this?
- What problems/advantages can this population growth cause the county?

Population Pyramids
A population pyramid: also called an age pyramid or age picture diagram, is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing

Government Policies on population Control
Pro-Natalist & Anti-Natalist
|
Task:
You will be conducting a debate on which Government policies to control population work best. However, before you start you will have to research these policies. Create a brief overview of each policy- 2 documents (maximum 1 side of A4) Pro-natalist: France Anti-natalist: China
