Chapter 2 Flashcards
Facts about East Asia
-1/4 of the world’s population -Chinese population is clustered near the Pacific Coast+ in several fertile river valleys-more than 1/2 of the people live in rural areas-China=worlds most populous country-4th largest country in land area
Facts about South Asia
Population is heavily concentrated near India’s to coast-lines -the Arabians sea to the West and the Bay of Bengal to the east -populated along the Ganges river+ Indus plains - Lahore, Pakistan, India, Bangladesh, Bay of Bengal,= largest concentration of people
Facts about Southeast Asia
About 600 mill. people live mostly on a series of islands that lie between the Indian and Pacific oceans -Indonesia= fourth most populous country- river valleys and deltas are clustered -Largest population concentration= island of Java
Facts about Europe
3/4s of Europe’s people live in cities, highest population concentrations= near the major rivers and coalfields of Germany, Belgium, London, Paris -four dozen countires, fewer than 10% are farmers
Facts about Eastern North America
cluster goes along the Atlantic coast from Boston to Newport, News Virginia and Westward along the Great lakes to Chicago
Facts about West Africa
Largest cluster=Atlantic coast -Nigeria=most populous country -agriculture
Define ecumene
The portion of Earth’s surface occupied by permanent human-settlement
Define non-ecumene
The portion of the Earth’s surface that is considered too harsh to settle on-ex: Antarctica
Dry lands-why cant people live there
too dry for farming. no farming=no food= you be dead. Deserts=no water, too hot
Wet lands-why cant people live there
Receives very high levels of rain+heat. rain+heat=nutrients depleting from the soil. no fertile soil=no crops=you be dead
Cold lands-why can people live there
ice everywhere= unable to grow food=you be dead, too cold to live there
High lands-why cant people live there
High elevation+steep mountains makes it challenging to settle -also covered n snow=hard to grow crops. no crops = you be dead
Define Arithmetic density
The total number of objects in an area. population divided by land
Define physiological density
The number of people supported by a unit area of arable land (arable land=land suited for agriculture)
What occurs when the rate of physiological density increases?
There will be less arable land for people and the availability of land could run out
Define agricultural density
The ratio of the number of farmers to the amount of arable land
Define crude birth rate (CBR)
The total number of live births in a year (for every 1000 person alive in the society)
Define natural increase rate (NIR)
The percentage by which a population grows in a year
What is the NIR today?
1.2 (population of the world has been growing 1.2% each year)
When did the global NIR peak, and what was it?
2.2, 1963, baby boomers
About how many people are being added to the worlds population each year?
About 82 mill people
Define Doubling time
The number of years that are needed to double a population
In what world regions is most growth occurring
Sub-Saharan Africa, South Asia, equally divided in East Asia, Southeast Asia, Latin America, Southwest Asia+ North Africa
Define total fertility rate (TFR)
The average number of children a woman will have throughout her child bearing years
What is the global “average” TFR?
2.5% -exceeds 5% in Sub-Saharan Africa, 2% or less in nearly all European countries
Note the rates and locations of the global “highs and lows” in TFR
Higher fertility rates in developing countries
Lower fertility rates in developed countries
