1. Population Geography Where do people live …and why??

2. Population Concerns: 3/4 of the worlds population live on approximately 5% of the earths surface!!
WG6A, 6B, 8C
Ask students why they think this is so (answers on next slide)
Why are there are more people living in certain area? Fewer people in other areas?
Most live between 20 and 60 degrees N latitude..why do you think this is so?
This is a Goodes Interrupted/Equal Area map projection
Five most populous countries (in order) China, India, US, Indonesia, Brazil
Ask students why this is so…India will pass China in the students lifetime (China one child policy, India is experiencing a populaion growth)

3. People Tend to Live Where There is/Are:
Seaports
Good water sources
Nice climate
Fertile soil
Urban areas (jobs etc)
Transportation
Resources
Technology (would you live somewhere w/o electricity, cable or internet & phone service??)

4. World Population Growth: Let’s look at how population has grown over time…
WG7C
Dot video embedded on lower left hand corner!
7 Billion and Counting Video

6. Population Pyramids Inverted bar graphs that show:
Age Distributions in a particular area (city, state country etc)
Sex Ratio: Male vs. Female
WG7A
What does a population Pyramid show us? (more on these in a separate lesson!)
What is happening in Italy? Russia? Nigeria?

7. Total # of live births for every 1000 people.
Birth Rate:
Total # of live births for every 1000 people.
Why is the BR so low in some areas? Basically, why are infants dying at a more rapid rate in some areas?

8. Total number of deaths for every 1000 people.
Death Rate:
Total number of deaths for every 1000 people.
DR high in developing countries = lack of medical care, nutrition
Why is the death rate high in some areas & low in others?
Look at Africa & eastern Europe, Afghanistan & Pakistan. What do these countries have in common? WAR!!!

9. Migration: Why do people move?
Push Factors
Pull Factors
WG7B, 7C
Have students come up with these as a class…
Some examples:
PUSH: plagues, wars, famine,
PULL: jobs/industrial revolution, better education opportunities

10. Rate of Natural Increase:
The % growth of population in a year (BR-DR = RONI)
WG8C
What do you think is happening where the population is exploding/growing?
What do you think the US & Europe might have looked like during the Industrial Revolution (better technology = able to grow more crops = able to feed more people = people having more children. Similar with the Green Revolution in India (push to grow more crops, feed more people – thus populaiton explosion)

11. Infant Mortality:
Number of deaths of children under the age 1 per 1000 people in the population.
WG7C
High infant mortality tends to result in higher fertility rates as families seek “insurance” for the loss of children. In many countries children are the primary caretakers for their parents.
Infant mortality is very high in developing countries. For instance, some African countries have an infant mortality rate that is over 10%.

12. Life Expectancy = How long a person will live.
People live LONGER in developed/industrialized countries - better medical care.
WG 7A
Q: Statistically, women live longer than men. Why?
A: Less stressful jobs (1950’s more men worked manual labor & stressful jobs. Women worked more in the home)

13. Let’s Recap… Developing Countries Industrialized Nation
HIGH  LOW Birth Rates
HIGH Death Rates
HIGH Infant Mortality
Life Expectancy = LOW (dying young)
Nat Geo Are You Typical? Video
LOW /EVEN Birth Rates
LOW Death Rates
LOW Infant Mortality
Life Expectancy = High (live to be old)
We will talk more about Demographic Transition Stages in the next units…
