1. Do Now/Silent 10
Name 3 areas you think have low population and 3 areas you think have high population
Why do you think some places have high or low population

2. Vocabulary-define these
Birthrate
Death Rate
Natural increase
Migration
Demographic Transition
Doubling Time
Population Pyramid
Population Distribution
Population Density

4. Let’s explore!
/2015-world-population-data-sheet/world- map.aspx#map/world/population/2015

5. Read: Demographic Transition Model (pg 87)
Use the reading to try to answer these 2 questions
How and why might the birthrate be different in industrialized vs. non- industrialized places?
What about the birthrates in these 2 places is similar?

6. Page 6-7 1. Which continent has the highest population density?
2. What areas of that continent are more densely populated?
3. What factors might affect population growth?
4. Why do you think there are areas with a very low population density?
5. What do the black squares on the map represent?

8. POPULATION PYRAMIDS

10. What are we going to learn?
WHAT is a population pyramid?
HOW de we read a population pyramid?
Recognize SHAPES of population pyramids.
IMPORTANCE of population pyramids.

11. What is a population pyramid?
It is a diagram that gives information about the proportion of males and females in each age group in an area, and also helps make predictions about future trends in that area

12. What’s it look like? What are the components?
Vertical Axis - Age Groups
Horizontal Axis – Percentage / number

13. Rapid Growth or Triangular-shaped Pyramid
Why would this pyramid represent rapid growth?
More kids than adults-population grew rapidly because a bunch of kids were born all around the same time.

14. Rapid Growth or Triangular-shaped Pyramid characteristics
Shape: Broad Base/bottom - high birth rates
Narrow Top - small elderly pop
- high death rate
Proportion: Large proportion of young
High young dependency ratio
Gender Ratio: Balance pyramid - Balance gender ratio

15. Slow Growth/Stable Growth Pyramid
Why would this pyramid represent slow or stable growth?
There have not been any significant or rapid changes in the population

16. Slow Growth/Stable Growth Pyramid
Shape: Rocket-shaped / Narrow Base
Slow pop growth
Proportion: Large proportion of working
population, yr old
Gender Ratio: Balanced pyramid

17. There has been an decrease in the population
Declining Population
Why would this pyramid represent a declining population?
There has been an decrease in the population

18. Declining Population Pyramid
Shape: Reverse pyramid shaped - Zero Pop Growth Narrowing Base - Low Birth Rates
Proportion: Bars of equal length - Balance
Proportion
Gender Ratio: Balance pyramid - Balance gender Ratio
