Earth’s Human Geography Population Notes
2
Where do People Live?
3
Key Terms Population Population Distribution Demographer Population Density Total number of people Way population is spread throughout earth People who study world’s population Average number of people per square mile
4
Can you guess the top 10 most populated countries in the world?
5
1.China 1,336,718,015 2.India 1,189,172,906 3.USA 313,232,044 4.Indonesia 245,613,043 5.Brazil 203,429,773 6.Pakistan 187,342,721 7.Bangladesh 158,570,535 8.Nigeria155,215,573 9.Russia 138,739,892 10.Japan 126,475,664
7
Why is Population Distribution Uneven? People are choosy What determines a good location 1.Rivers and Lakes 2.Flat, fertile soil 3.Flat plains and coastal areas 4.Reasonable climate 5.Adequate rainfall 6.Natural resources for building and producing
10
89% of people live on which 3 continents in the world? Asia, Europe, North America They total only 53% of the world’s land Why do you think this is
11
Continents Populous and Not Populous Why do some continents have low population? Bad climate Not enough rainfall Bad land quality
12
Example: Australia: roughly size of USA Population of Australia: 19 million Population of USA: 301 million *Population of Australia is about the population of New York*
13
Australia Australia’s Physical Features Mostly dessert Dry Grassland Little Rainfall and Few Rivers
15
Africa 20% of the world’s land 13% of the worlds population What type of land and climate does Africa have?
17
What is population density?
18
Average number of people who live in a square mile
19
How to you calculate population density? Total population _________________ Total number of sq/mi
20
Population Density What is the difference between high density and low density? High density: people are crowded together Example: Japan: 25,000 people per sq/mi Low density: people are not crowded Example: Canada: 9 Example: Canada: 9 people per sq/mi
21
Studying Population Density Population Density is an average Example: New York City: very dense population New York State: many fewer people per sq/mi
22
Studying Population Density World population map Darker colors: heavy population Lighter colors: less population
24
Studying Population Density People tend to live on level areas near bodies of water Example: Nile River Location: Africa Land around the Nile: high population Land not near the Nile: Low population Why do you think this is?
25
Studying Population Density Some people do live in “uncomfortable areas” Examples: Inuit and Sami live in frozen Arctic Regions Herders in desert regions of Africa and Asia These people have developed ways of life suited to their environments Why do you think this is?
26
Lets Review….. 1.How do physical characteristics of a country (land type, access to water) affect its population distribution? 2.Why is it important to understand population density as an average? 3.A large percentage of the world’s population lives on a small percentage of the worlds land. Why is this? 4.Would you rather live in a place where the population density is high or low? Explain. 5.Name a city, country and continent with a dense population Answers:
27
Population Growth Notes
28
Key Terms Birthrate Death rate Life expectancy Green Revolution Number of live births each year per 1000 people Number of deaths each year per 1000 people Average number of years people live Changes in agriculture that have greatly increased the world’s food supply
29
Population Growth is Worldwide 1960: World Population was 3 billion 2000: World Population was 6 billion 9/23/13 at 8:55 AM: World Population is:7,180,325, 610 What are the top 3 most populated countries in the world?
31
Population Birthrate and Death rate Population grew at different rates throughout history Population grown depends on birthrate and death rate 100 years ago in USA: men and women lived less than 50 years. Why do you think that happened?
32
Life expectancy timeline Analyze the moving timeline of the world’s life expectancy and think about the following questions: Did life expectancy steadily increase throughout history? Why?
33
Why is the earth’s population growing so quickly? Birthrate increased and Death Rate slowed US: average life expectancy for women is 80 and men is 73 Reasons for this: New Farming Methods Scientific advancement in medicine and health
35
What are challenges of rapid population growth? 1.Public transportation and sanitation inadequate 2.Shortage of fresh water 3.Shortage of food supply 4.Shortage of energy 5.Job shortage 6.Overcrowded schools 7.Decent housing is scarce and expensive
36
Most visible in South Asia Home to ¼ of world’s population Also home to ¼ of world’s poor 1 out of every 14 children born will die before age one Where is rapid population growth most common?
38
What would the world look like with equal proportion for land mass and population? What would the world look like with equal proportion for land mass and population?
39
The Challenges of Population Growth Rapid growth affects the environment Forests in India and Pakistan are disappearing Affects clean air supply The earth’s resources must now be shared by six times as many people than in earlier times.
41
Lets Review…. 1.Why has the world’s population increased so dramatically in the last four or five decades? 2.How have science and technology contributed to the growing population? 3.The world’s population has been growing at a fast rate. What are some of the dangers of a rapidly increasing population? 4.World Hunger is one of the major concerns caused by rapid growth population. Write one or two suggestions to help solve the problem.
42
Why People Migrate Notes
43
Key Terms 1.Migration: 2.Immigrant: 3.“push-pull” theory: 4.Urbanization: 5.Rural area: 6.Urban area: moving from one place to another people who leave one country and move to another certain things in their lives “push” them to leave and certain things in a new place “pull” them. movement of people to cities and the growth of cities villages and countryside areas cities and busy towns
44
Questions to Focus on…. 1.Why do people migrate? 2.What are some important population issues?
45
Why do people migrate?
46
Migration: The Movement of People For centuries people have moved from one place to another Millions of immigrants come to US Push-Pull theory Push: religion, land Pull: Hope for a better living
47
Irish Immigrants in the USA 1840’s and 1850’s 1.5 million left Ireland for the USA Why did they leave? Potato Famine 1840’s Hunger and Starvation England ruled Ireland harshly Few opportunities for job improvement
49
Vietnamese Immigrants to the USA Southeast Asia to USA Vietnam War, Communism caused many to flee Other countries would not accept these people but the USA did Push-Pull Theory: Push: communism Pull: USA welcoming immigrants
50
Did you or any members of your family or your ancestors immigrate to the US? Why?
51
Other Kinds of Immigration Australia: colonized by English; convicts sent there to serve sentences, some stayed War forces migration People helping their families forces migration Can you give an example of the two above?
52
The World Becomes more Urban Migration occurs within a country Americans migrate more than citizens of any other country Population shift in the US from northeastern states to southeastern and southwestern states. Problem: southwestern cities having enough water supply
53
The World Becomes More Urban Biggest challenge today: people moving from farms and small villages to cities Urbanization has grown What pushes people from rural areas? What pulls people to cities?
55
Growing Cities, Growing Challenges Indonesia Past: many people were farmers, fishers and hungers They lived in rural areas Present: they are now moving to urban areas *Example: Jakarta (capital of Indonesia) 1978: population 4.5 million 2000: population: 11 million 2015: population: expected 21 million
57
Waste Dump: Jakarta, Indonesia
58
Growing Cites, Growing Challenges Sao Paulo, Brazil too many people coming too fast Cities cannot provide: Housing Jobs Schools: crowded Hospitals Transportation: 4 million buses and cars pollute air Other services needed Fewer farms: less food Overcrowding everywhere: huge problem
60
Growing Cities, Growing Challenges If cities are so overcrowded, why would people still go there? Seeking a better life Looking for jobs Looking for decent housing Looking for good school Most want more opportunities for children
61
Lets Review…. Why do people migrate? Why have some immigrants left their homelands to live in the United States? (list at least 3) Describe how urbanization happens. List at least 3 examples for push factors and pull factors. Push- why people leave areas Pull: Why people come to new areas Answers:
