Use book pages 58-65
What are we going to be studying about? Come up with 10 topics, write on page 11 in your journal.
Pages 471 and Population density maps
Where are people living? Why?

3. Bellringer – Pg 11
Add this to last week’s bellringer List the oceans and the continents.

4. Population Density

5. Population Distribution

6. Why do they live in these places? Why do they not live in others??
World physical map page A2

7. World Population Growth
Why the HUGE growth in the 20th century (1900s)
You will share your conclusions with the class

8. POPULATION PYRAMIDS PG 12

9. Objectives WHAT is a population pyramid?
HOW to read a population pyramid?
Recognize SHAPES of population pyramids.
IMPORTANCE of population pyramids.

10. What is a population pyramid?
It is a diagram that gives information about the proportion of males and females in each age group.
Also shows:
- proportion of young people (0 -14 )
- proportion of working people (15 – 59)
- proportion of elderly people (60+)

11. What is a population pyramid?
Vertical Axis - Age Groups
Elderly dependents
Working population
Young dependents
Horizontal Axis – Percentage / number

12. How to read a population pyramid?
Read the title e.g. country or city or racial group
Comment on general shape of the pyramid
Note the proportion of people in various age groups
Note the sex ratio
Interpret the data

13. Types of Population Pyramid
1. Triangular-shaped
2. Beehive-shaped Pyramid
3. Rectangular-shaped Pyramid
Shape of pyramids is controlled by
births,
deaths, &
migrations.

14. Triangular-shaped Pyramid (Broad-based Pyramid)

15. Broad-based Pyramid Title: India, 2000
Shape: Broad Base - high birth rates
Narrow Top - small elderly pop
- high death rate
Proportion: - Large proportion of young
- high young dependency
ratio
Sex Ratio: Balance pyramid - Balance sex ratio

16. For your notes Draw a triangle shape pyramid
Broad Base = high birth rate
Narrow top = high death rate, low elderly population

17. Indonesia
2000
Malaysia
2000

19. Beehive-shaped Pyramid

20. Beehive-shaped Pyramid
Title: Singapore, 2000
Shape: Rocket-shaped / Narrow Base
– Low Birth Rates, Slow pop growth
Proportion: Large proportion of working
population, yr old - large
group of economically active pop
Sex Ratio: Balanced pyramid

21. For your notes Draw a beehive pyramid
Narrow base = low birth rate and slow growth
Large middle = lots of workers

22. Hong Kong
2000
Taiwan
2000

23. Rectangular-shaped Pyramid

24. Rectangular Pyramid Title: Netherlands, 2000
Shape: Rectangular-shaped - Zero Pop Growth
Narrow Base - Low Birth Rates
- Life-expectancy is high e.g. 80+
- Low death rates
Proportion: Bars of equal length - Balance
Proportion
Sex Ratio: Balance pyramid - Balance Sex
Ratio

25. For your notes Draw a rectangle pyramid
Rectangle = zero population growth
Narrow base = low birth rate
Low death rate
High life expectancy

26. UK 2000
Netherlands
2000

28. Population Pyramids in Transition

29. Each pyramid tells a story about the past, present & future of a country & its people.

30. Importance of Population Pyramids
Policy Planning
~ future housing estates
~ future schools
~ future jobs
Comparison with other countries
~ developed (US) vs developing (India)

31. Your turn…
Look at the shape
Find the trend
Remember your basic shapes

33. United States, 2000 More boys in younger age groups than girls
Reversal of ratio in upper age groups
Shifts around age 35
Slow growth

35. China, 2000
Efforts to reduce the birth rate have contributed to a prominent male majority.
Since the early 1980s, parents try to have a male child if they are only having one child
Boys culturally seen as more beneficial than a female
Imbalance
Could lead to instabilities

37. Mexico, 2000
Pyramid shape
Rapid growth

39. Iceland, 2000 Generally straight except for older age groups
Stable population

41. Japan, 2000
Top-heavy shape
Shrinking population

43. Germany, 2010
Negative growth

45. Sweden, 2010
Somewhat stable; could be beginning a pattern of negative growth

47. Kenya, 2010 Looks like slow growth Dying younger
The situation in Kenya: young adults with AIDS are dying leaving a very young population in its place

49. Brazil, 2010
Looks like the pattern of rapid growth was interrupted by something
Growth rate is again rising

51. Russia, 2010 Very unbalanced at top between males and females.
Transitioning between patterns of rapid growth; either slowing or beginning to grow again.

53. North Korea, 2010
Beginning period of negative growth
Had previously experienced rapid growth
Females outnumber men in older ages

54. Glue your created population pyramid to the back of page 12

55. Exit Slip What shape is your population pyramid?
What does that tell you about the
Age groups (youth, working, elderly)
Sex
Growth

56. Levels of Development More Developed Less Developed
GDP per capita of $25,000 or more
Low life expectancy
Less than $8,000 GDP per capita
Literacy rate at/near 99%
Technology
Large rural population
Industrialized
High infant mortality rate
Varied distribution of labor
High birth rate
Large Urban population
Newly Industrialized
High life expectancy (above 76)
$ ,000 GDP per capita
Growing urban population
Growing technology

57. Definitions for your notes – Pg 12
More developed
Newly industrialized
Less developed
