Sep 13: doubling time, population pyramids & why/how they are used

Today we will take a look at Doubling Time calculations -- how they are useful and what their limitations/weakness are; we will also do the same for Population Pyramids.

We then will catch up and watch the NOVA population videos (part 1: India and Part 2: Japan).
Helpful Resources for today's class:

• Interpreting Population Pyramids (Google Slides)
• Population Pyramid Examples (Google Slides)
• PopulationPyramid.net
• ABC-CLIO - World Geography (use school username/password -- can find this by going through Library Resource Databases in Schoology)

HW: Study for Formative FRQ on Friday, sep 15

To prepare for the Unit 2 Formative FRQ #1 (early key issues/questions for Population), please work on the study guide. 
The Chapter study guide has been placed in your APHG Drop folder.
Focus on completing sections of the study guide for Key questions/issue #1 and #2 and #3.  
You will not need to know how to calculate Doubling Time or read Population Pyramids, or read the DTM, but understanding these models and how they help us answer the key issue questions is potentially helpful. You will be tested on Doubling Time, Population Pyramids and DTM at a later date--not Friday. For Friday, focus on patterns and trends with population distribution and demographic dynamics (complexity of factors and conditions that can affect where people live and the rate at which a population increases or decreases). Consider examples we've focused on (Japan, Singapore, India, etc.)
The FRQ will require you to know how to respond to the key issues:

• Where is the world's population distributed?
• Why is global population increasing?
• Why does population growth vary among regions?

If you need a more thorough review of the key questions/issues, there are tutorial videos on the APHG course Unit 2 webpage  -- these videos explain concepts for each key issue and possible answers to the key questions.
