  1. Wednesday 15th September 2011 Population Structure Lesson Objective: To be able to construct and interpret population pyramids and understand their characteristics.

  2. Starter • LEDCs have high…? • LEDCs have low…? • MEDCs have low…? • MEDCs have low…?

  3. Demographic Transition model. (DTM) Population Pryamids. Two types of graph…both can tell us a lot about the structure of a country’s population.

  4. WHAT DO POPULATION PYRAMIDS SHOW? • The population of a country or region divided into five-year age groups. • The percentage of people in each of these age groups. • The percentage of males and females in each age group. • Changes in birth rate, death rate, life expectancy and infant mortality. • The proportion of elderly and young people who are dependent upon those of a working age – the economically active. • The effects of people migrating in or out of a country or region.

  5. WHAT TYPES OF PYRAMIDS ARE THERE? There are 2 main types of pyramid. • Stationary Pyramid. • Expansive Pyramid.

  6. STATIONARY MAINLY FOUND IN MEDCs, e.g. The UK, France & USA

  7. EXPANSIVE MAINLY FOUND IN LEDCs e.g. Ethiopia, Kenya & Peru

  8. Population pyramids from around the world. http://www.census.gov/ipc/www/idb/pyramids.html Examples: Ethiopia, USA, Sweden.

  9. TEXTBOOKS: Foundation Wider World [FWW] pg. 8, 9 14 & 15 Understanding GCSE Geography [UGG(f)] pg.108 & 109 Activities • Read pg. 8 & 9 FWW Complete Act. 6 and 8 (pg. 14) • Sketch on to your A3 DTM sheet from last lesson the population structures for Stages 1 to 4 from Diagram C (pg. 9). Now sketch on to the sheet what you think Stage 5’s population pyramid would look like. • Draw a population pyramid for the UK, using 2004 census data. (Link:http://www.geography.ndo.co.uk/excel/drawing%20population%20pyramids.xls) • Read pg. 108 & 109 UGG(f). Complete Act. 1 and 3.

  10. Jelly Baby Population Game

  11. The sweets represent your population. Make a note of your population structure. Shuffle the chance cardsand put them in the middle of the table. Each country takes it in turn to take a card from the top of the pile. You must carry out whatever instructions are on the cards. If you lose any of your population DO NOT EAT THEM! Put them back into the central dish. You will be told when the game ends.

  12. After you have finished the game • Which things changed the birth rate? • Which things changed the death rate? • Which things changed the migration rate? • Which things were push factors (reasons to leave your home country) of migration? • Which things were pull factors (reasons to attract you to a foreign country) of migration? • Who do you think won? What makes them the winning country? Is it the country with the highest population or the most balanced population structure?

  13. Population Bingo! Pick six different key words from the list below and put them in a grid like this… Plenary • Population • Density • Distribution • Sparse • Dense • Physical • Human • Conurbations • The Pennines • Climate • Edinburgh • Belfast • Cardiff
