Age / Sex Structures
(AKA Population Pyramids)
(AKA Population Pyramids)
Objective: To be able to effectively read and interpret population pyramids.
Use this sheet to annotate how to read a population pyramid using shape and then what shape indicates.
See this example from 2017.
Worksheet is above for all of the following activities.
Starter: Click here to be taken to a population pyramid of France this year. Study it carefully and then describe why the French President needs to raise the retirement age by two years for French workers.
Task 1 - Watch the video and explain the features of the Age Sex Structure for France. What does the term ‘spinning top’ refer to?
Task 2 - Have a play with this population pyramid site - check out your own country.
Screen shot the pyramid for when you were born, for when you will be 50 and for when you will be 100 (maybe!)
Then write a few sentences to explain what future population growth / decline is going to be like there.

Task 3 - Age Sex Structure - Your go...!
You are going to complete a data task to construct your own age / sex structure for France in 2016.
You will need a printed out copy of this worksheet and this data set from http://www.insee.fr
Note, it will be better if you work in groups to work out the total number of males and females in each age range. Each age category found on the Word Document is differentiated on the Excel sheet by a different colour. Round up or down to the nearest 100,000.

A country with a high dependent population
|
|
Objective: To find out what causes a youthful population structure to occur and to discover what happens when a country has a high dependent population (in this case - too many young people).
Dependent people can be classed as those on a population pyramid who are either under the age of 15 (young dependents) or over the age of 65 (old dependents). This is because people in these age categories generally don't work and are supported by people in the economically active sector aged 16-64.
This is quite a general assumption and there are many factors that might mean that children may actually work before 16 or that elderly people still work into their 70's. Study the population pyramid for The Gambia above. The wide base shows a high fertility rate and a high youthful population (high young dependents).
Task 1 - Download the worksheet above and complete all activities, apart from the 7 mark question at the end.
Task 2 - Now download this fact sheet on the Gambia and read the content carefully. Also, watch the video below created by an IGCSE student. Now complete the following 7 mark Paper 1 question in the space provided on the worksheet.
For a named country you have studied, describe the problems caused by a high dependent population.

Is it fair to say that HIV infection rate is on the decrease worldwide and that the news is only bad in Africa?
Focus on Southern AfricaSo how does all of this affect population structures? We are going to be using Botswana as our focus for how AIDS can affect a population structure. Spend 2 minutes exploring Botswana on the Google Map. Make some notes about its human and physical geographies. Click here to be taken to some familiar population pyramids structures for Botswana. Task 5 - Take a copy of the population pyramid and bar chart before using them to respond to the following IGCSE Population exam question: Explain, using examples, how incidences of disease can affect the population structure of a country. (7) This should take you approximately 14 minutes to respond to. Structure:
