1. POPULATION and Urban Development
Thought Questions:
1. What things would cause people to leave a certain place?
2. What factors would cause people to move to a certain place?

2. PUSH & PULL FACTORS
The push factor involves a force which acts to drive people away from a place.
The pull factor is what draws people to a new location.

3. Migration – Push & Pull Factors
Most people move because of economic or political reasons
Pushed from a bad situation
Less developed country
Pulled to a better situation
More developed country, access to resources, better economy
People also move from rural to urban areas
Huge demand on city infrastructure and economy
Job market, living quarters

4. Urban Development - 3 Basic Land Use Patterns
Residential – Single family housing and apartments
Commercial – Used for private businesses and retail.
Industrial - Areas reserved for manufacturing

5. REGIONS
Part of the Earth’s surface that is alike or connected in some way, such as by politics, economics, culture, or environment.
1) Formal Region, 2) Functional Region, and 3) Perceptual Region

6. DEMOGRAPHY Demography: The study of population
Demographer: A person who studies demography
Demographics: the statistical data of a population showing age, gender, income, education, etc.

7. GLOBALIZATION
Describes an ongoing process by which regional economies, societies, and cultures have become integrated through a globe-spanning network of communication and trade.

8. World Geography Population
Eastern Asia has the greatest concentration of people on Earth – it is centered in China and has 21% of Earth’s population.
2) Southern Asia is the second largest concentration of
people – it is centered in India and has 16% of the Earth’s pop.

3) Western Europe is the third largest concentration.
In Western Europe people are concentrated near natural resources needed for industry.

10. World Geography Population
East Central North America is the fourth largest center concentrated in the NE US and SE Canada.
In the US, the chain of cities start from the city of Boston to south of Washington DC.
- This is called a megalopolis.

11. World Geography Population
Africa has 12% of the Earth’s population.
Largest cluster of people found in the Nile River Valley.
Cairo is the largest city in Africa.

12. World Geography Population
South America is lightly populated compared with other continents.
Patterns of people live along the edges of the continent – SE Buenos Aires in Argentina, Montevideo in Uruguay, and Rio de Janeiro and Recife in Brazil.

13. World Geography Population
Australia has the fewest number of people.
They are concentrated along the eastern and southern coasts.
(17.5 million people total on the entire continent. – as much as the NYC metro area)

16. Population Density The number of people in a unit of space
Example: 8,000 people per square mile

17. World Geography Population
Population Issues – The 20th century world population "explosion," from 1.6 billion in 1900 to 6.1 in 2000, was a direct result of the rapid decline in mortality rates in less developed countries. As death rates declined, life expectancy rose, leading to higher population.
Population explosion issues:
how to increase food supplies
how to make better use of farmland
how to improve eating habits and to take advantage of resources
how to find new sources of food.

18. World Geography Population
Food Supply
The rate of population growth was more than the amount of food produced.
More than 13 million to 18 million people die each year because they do not have a good diet.
(35,000 a day; 24 a minute – most are children)
More land is needed for agriculture
Productive farming methods
More productive farming techniques
Using new food sources
New sources of food
Today 90% of the world’s food comes from 15 crops and 7 livestock animals.
There are more than 10 million kinds of plants and animals on Earth.

19. LEVEL OF DEVELOPMENT & STANDARD OF LIVING

20. Over Population
Over Population: the number of people exceeds the resources available in an area
Carrying Capacity: the number of organisms a piece of land can support without negative effects.

21. POPULATION PYRAMIDS

22. Population Pyramids
Graph that shows the percentage of population in certain age groups
Separates Male and Female

23. Deciphering Population Pyramids
In this first video, "Deciphering Population Pyramids," PRB senior demographer Carl Haub shows how population pyramids give us a snapshot of a country's demographic profile. But what do they tell us about a country's past and future? "These videos not only show that demography can be exciting, but also highlight how population trends and issues affects the well-being of us all," says Haub. "Fertility, mortality, and migration—along with other demographic issues—play a major role in determining what kind of opportunities and challenges people face in their communities and countries."

24. Stage One High Birth Rate High Death Rate Result: slow growth rates
Pre-industrial, hunter/gatherer societies in remote areas.

25. Stage Two High Birth Rate Low or Falling Death Rate
Result: Rapid Growth Rate
Very LOW Standard of Living
Found In Least Developed Countries
South America
Southern Africa
Asia

26. Stage Three
Moderate to High Birth Rate
Low Death Rate
Result: Explosive Growth Rates
Causes a large population increase, but standard of living remains low
Developing Countries and the Newly Industrialized Countries
Found In Countries:
Mexico
Southeast Asia
Middle East

27. Stage Four Low birth rates Low death rates
Result: slow or no growth rates
Population slowly increases, with a high standard of living
Developed Countries
USA
Canada
Australia
Europe

28. Stage Five Negative Birth Rate Low Death Rate
NEGATIVE or NO GROWTH
Low Death Rate
Result: No growth, even population loss
Population begins to shrink, usually has a high standard of living
Found In “Post-Developed” Countries
Germany
Sweden
Norway
Italy

29. High fertility and mortality = broad base
Rapid, Slow, Zero and Negative Population Growth
High fertility and mortality = broad base
Low fertility and mortality = narrow base
