Population

Family SizeHow many children (if any) do

you want to have?How many siblings do you have?How many do your parents

have?

Any trends??? Explanations???

Key Issues1) Where is the world’s population

distributed?2)Where has the world’s population

increased?3) Why is population increasing at

different rates in different countries?4) Why might the world face an

overpopulation problem?

Case Study: Population Growth in India p.46 Why does the Indian gov’t hope that

women will have LESS babies than their mothers?

Demography The study of population characteristics

Age, gender, occupation, fertility, health, etc

Describe the demographics of Kennedy High School Why do administrators & teachers study

the demographics?

4 most populous regionsE Asia, SE Asia, S Asia, W Europe

Similarities:Most live near ocean or a river with

access to oceanLow-lying areas, fertile soil, temperate

climateMost in Northern Hemisphere (SE Asia

exception)WORLD POPULATION

2/3 live within 300miles of ocean (6hrs drive)4/5 live within 500 miles of ocean

East Asia: 1/5 of world’s population

Label & ColorEastern China, Japan, Korea, TaiwanChina: world’s most populous country,

3rd largest in area Population clustered near Ocean and river

valleys (Huang & Yangtze) 2/3 of population in rural areas, farmers

Japan, South Korea ¾ of population live in urban areas

South Asia: 1/5 of world’s populationLabel & ColorIndia, Pakistan, Bangladesh, Sri

LankaIndia: 2nd most populous countryHeavily populated near Indus and

Ganges Rivers and on India’s coastlines (Bay of Bengal & Arabian Sea)

Most in rural areas, farming

South East Asia: 4th largest population

Half billion peopleIslands between Indian and Pacific

oceans Indonesia: 4th most populous country

(Java: largest population), Sumatra, & Philippines

Large population of farmers

Europe: 3rd largest population cluster

Four dozen countries Monaco 1sq km (.7miles), to Russia (largest

country) ¾ of population live in cities, less than 20%

farmers Concentrations near industry: England,

Germany, Belgium Can’t produce enough food for inhabitants

Import foods, led to exploration/colonization

Other Population ClustersNorth Eastern United States (2% of pop)

Urban dwellers, less than 5% farmersSouth Eastern Canada

West Africa Nigeria Most work in agriculture

Sparsely Populated People avoid living in extreme areas

(elevation, climate, precipation, etc)Ecumene: portion of Earth’s surface

occupied by permanent settlement Increased over thousands of years (Why?) ¾ of population live on 5% of Earth’s surface Oceans make up about 71% of Earth

Ecumene

Sparsely Populated Regions Dry Lands: 20% of Earth too dry for farming

ex: Sahara Wet lands: near Equator of South America,

Central Africa & SE Asia. Rain & heat deplete nutrients in soil

Cold Lands: North & South poles: permafrost High Lands: mountains are steep & snow

covered. Ex: Switzerland half of land occupied by only 5% bc of elevation Exceptions occur to escape temps & precip

(Mexico City 7,360ft)

Population Density Number of people occupying an area of

land

Arithmetic Density Physiological Density Agricultural Density

Arithmetic Density Most common (population density) Total number of people divided by total

land area United States 300 million, 3.7million sq

miles About 81 per sq mile

Asia has high arithmetic density Canada has low arithmetic density

Physiological Density Number of people per unit area of

arable land Egypt is 6682 per sq mile US is 445 per sq mile Egypt has to support more people off

same amt of land Shows relationship of population

compared to availability of resources

Figure 2-5 Looking at the Physiological Density of

the world, which of the 4 most populous regions of the world has the highest numbers? What does that mean?

How does the United States compare?

Agricultural Density Ratio of number of farmers to amount of

arable land Why does US have low agricultural density

(1 farmer/sq km) compared to Egypt (826 farmers/sq km)?

MDCs have more technology (more efficient) Fewer people needed to farm Allows remaining population to work

elsewhere

Key Issue 1 SummaryWhere is the world’s population distributed? Summary: Global population is

concentrated in a few places. Human beings tend to avoid those parts of Earth’s surface that they consider to be too wet, too dry, too cold or too mountainous. The capacity of Earth to support a much larger population depends heavily on people’s ability to use sparsely settled lands more effectively.

Review Where is the world’s 4th largest

concentration of people? What is physiological density? How can you describe a country with a

lot of arable land a small amount of farmers?

What types of regions do people avoid? What area is an exception?

Review How would you describe a country with

a physiological density larger than it’s arithmetic density?

What are the four types of land that lie outside of the ecumene
