Why is it so important to study world population?
![Page 4: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/4.jpg)
Why is this important?

Two Types of Maps:
Reference Maps- Show locations of places and geographic
features- Absolute locations
What are reference maps used for?
Thematic Maps- Tell a story about the degree of an attribute,
the pattern of its distribution, or its movement.
- Relative locations
What are thematic maps used for?

Geographic Information System:a collection of computer hardware and software that permits storage and analysis of layers of spatial data.

Southeast Asia

![Page 31: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/31.jpg)
Sparsely populated regions:
![Page 32: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/32.jpg)
![Page 33: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/33.jpg)
Reliability of Population Data, Fertility/Mortality/Birth rate
Precursor to Demographic Transition Model
![Page 34: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/34.jpg)
![Page 35: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/35.jpg)
Population Change Measured:
• Crude Birth Rate (CBR)• Crude Death Rate (CDR)• Natural Increase Rate (NIR)
![Page 36: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/36.jpg)
Crude Birth Rate: CBR• Total number of live births in a year for every
1000 people.– What does a CBR of 50 mean?
![Page 37: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/37.jpg)
Crude Death Rate: CDR
• Number of deaths in a year for every 1000 people alive
![Page 38: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/38.jpg)
Natural Increase Rate: NIR
• Percent by which a population grows in a year– Subtract CDR from CBR after converting the
numbers to percentages– CDR 5 per 1000– CBR 20 per 1000
![Page 39: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/39.jpg)
Natural Increase Rate:
• NATURAL increase rate: How the population naturally increases.
• Does this include migration to and from the country?
![Page 40: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/40.jpg)
Doubling Time
• Rate of natural increase affects the doubling time: number of years needed to double a population (constant rate of natural increase)
• Rate of 1.2: in 2100 the population would be 24 billion
![Page 41: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/41.jpg)
Population Decline:
• What countries/regions?– NIR declining in Europe
![Page 42: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/42.jpg)
Differences in Growth Rates:
• Fertility rates• Mortality rates• We use both to explain how countries and
regions vary in population growth (or even population decline)
![Page 43: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/43.jpg)
Fertility• Crude Birth Rates: total number of live births a
year per 1000 people.• CBRs mirror Natural increase rates (NIRs) on
maps
![Page 44: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/44.jpg)
Mortality
• Infant Mortality Rate (IMR)– Annual number of deaths of infants under 1 per 1000 live
births• Life Expectancy
![Page 45: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/45.jpg)
Mortality:
• Life expectancy:– Average number of years a newborn
infant can expect to live – High life expectancy where?
![Page 46: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/46.jpg)
What is overpopulation?
Number of people exceeds the environment’s ability to support life
![Page 47: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/47.jpg)
Help?
• Economic growth must be faster than population growth
• --> impoverishment
![Page 48: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/48.jpg)
Global food production map

Government Policies: Cont’d
• Restrictive Population Policies– China: 1-child policy
(housing privileges, financial opportunities, education)• Abortion, female
infanticide, orphan girls
– India
![Page 50: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/50.jpg)
Migration
Permanent move to a new location
![Page 51: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/51.jpg)
Flow of Migration
• Emigration– Migration
FROM a location
• Immigration– Migration TO
a location
![Page 52: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/52.jpg)

![Page 54: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/54.jpg)
Push Factors vs. Pull Factors• Push Factor: induces people to move out of their location
• Pull factor: induces people to move into a new location
I think I need to move…
![Page 55: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/55.jpg)

Impact of Immigration
• Diffusion of culture– Religion– Art– Music– Literature– Philosophy– Ethics– Cultural traditions
![Page 59: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/59.jpg)
Impact of Illegal Immigration• Immigration allowance: high• 11.9mil undocumented, +500,000
come each year• 59% from Mexico• 22% from Latin America• 12% from Asia
![Page 60: Unit 2: Population and Migration](https://reader034.fdocuments.us/reader034/viewer/2022051420/56816029550346895dcf32c7/html5/thumbnails/60.jpg)
View from Mexico
• Mexico is both a source and destination
• Views from Northerners vs. Southerners
• Remittance
