Ch. 2 Key Issue 1: Where Is the World's Population Distributed?
Terms in this set (25)
o Human beings are not distributed evenly across the Earth.
-depict the sizes of countries according to population rather than area.
-the scientific study of population characteristics.
-look at how people are distributed spatially by age, gender, occupation, fertility, and health.
4 Major Clusters
• East Asia
• South Asia
• Southeast Asia
• Northeastern U.S./ Southeastern Canada.
-largest concentration in the western hemisphere.
• Largest cluster in West Africa is along the Atlantic Coast.
- 1/4 of the Earth population are located
- China, Japan, Korea, Tiawan
_ China is the most populated country, though most of its people live in rural areas.
- 1/4 population is located
- India, Pakistan, Bangladesh, Sri Lanka
_ Most of the population is concentrated along the Indus River and Ganges River plains.
- 4 dozen / 48 countries
-3/4 live in cities and fewer than 10% are farmers.
_ Largest concentration near major rivers, coalfields, and historic capitals
_ Russia is the largest in land area
- 600 million people
_ Population is clustered along river, valleys, and deltas in Indochina, most are rural farmers.
_Indonesia consists of 13677 islands, the largest concentration live on the island of Java.
- occurs when the people in an area exceeds the environmental capacity to support life at a decent standard of living.
-portion of the Earth's surface occupied by permanent human settlement
- 20% of the Earth's surface is too dry for farming.
-Deserts lack sufficient water to grow crops to feed a large population so some people raise animals, camels.
-Usually contain natural resources such as oil.
-Located primarily near the equator, receives high levels of precipitation, inhabitable by humans
-The combination of rain and heat depletes nutrients from soil, so no agriculture
-Land near the North and South Poles are with permafrost (permanently frozen ground).
-Polar Regions are unsuitable for farming, raising livestock, or human habitation.
-The highest mountains are sparsely settled, because of steepness and snow.
-Some low latitude plateaus and mountain regions are population.
o The number of people occupying an area of land
- the total number of objects in an area
-In population, it is the total number of people divided by total land area.
-Allows the geographers to compare the number of people trying to live on a given piece of land in different regions of the world.
-the number of people supported by a unit of arable land.
Ex: 95% of Egyptians live the Nile River Valley because it is the only area that receives enough moisture to all cultivation of crops.
Comparing physiological and arithmetic densities helps geographers...
understand the capacity of land to yield enough food for its people.
- land suitable for agriculture.
-The ratio of the number of farmers to the amount of arable land.
-have a lower agricultural density, because technology and finance allow a few people to farm extensive land areas and feed many people.
Some countries have similar physiological densities but produce different amounts of food...
because of different economic conditions.
Where is the world's population distributed?
- Most of the world's population is highly distributed in the four major clusters.
-Arithmetic, physiological, and agricultural densities are different approaches to describing the distribution of people
