Demographic Transition
(definition and 4 types)
Age Structure Diagram
Population Pyramids-Age Structure Diagrams: You have to be able to answer questions about age structure
diagrams.
Write the name(s) of the countries described by the following statements.
1.
2.
3.
4.
5.
Has completed demographic transiton.
In the pre-industrial stage.
Close to zero population growth.
Has high birth and death rates.
What precentage of the male population is 0-4 years old in each country?
Stages of Demographic Transition: You need to know the stages and characteristics or each stae of demographic
transiton.
Write the descriptions under the stage they describe.
High birth rate and death rates
Low birth and death rates
Birth rate declines rapidly
Small population
Large population
Death rate declines (use twice)
Population grows rapidly (use twice)
Population levels off
High infant mortality low life expectancy
Elderly outnumber young
Need children to work farms
Children are not a necessity but parents still want them
Many families choose not to have children
Children still necessary, families have more money
Pre-Industrial
Transitional
Sketch a population pyramid for each stage.
Industrial
Post-Industrial
Exponential and Logistic Graphs: You will have to interpret data in exponential and logistic graphs.
The graph shows the growth of 2 species of bacteria grown on the same petri dish. It also shows their growth
rate when grown separately.
1. Which of the 2 types of bacteria will soon die? Why?
2. Which of the 2 bacteria strains is better adapted for competition?
3. How is the growth rate for P. caudatum different when it is grown alone?
4. When does P. aurelia reach its carrying capacity?
5. Is this exponential or logistic growth? Explain.
Calculating Population Growth Rate and Doubling Time: You need to be able to do this.
Growth Rate for a nation or region = (CBR –CDR) + (Net Migration)
10
Doubling time (in years):
70______
Growth rate (r)
Use the formulas above and the information in the chart to calculate the growth rate and doubling time for the
following areas.
Country
Birth Rate
births/1000
population
Death Rate
deaths/1000
population
Net Migration
migrants/1000
