Give an example of a map that would have a ‘large scale’
What map projection distorts the size of land masses close
to the poles?
If a city is found at: Latitude: 43° 40' 0 N, Longitude: 79° 25' 0 W, what
continent is it on?
Another word for Perceptual Region is?
Give an example of distance decay:
Give an example of hierarchal diffusion:
Give an example of relocation diffusion:
Where is the world’s population distributed?



More people today than
ever before (7.3 billion)
World’s population
increased at a faster rate in
the 2nd half of the 20th
century than ever before in
history
Almost all pop. Growth is in
LDCs



Generally has meant growth (global scale)
Regional examples of pop. decline usually
short term (war, disease, famine)
These 2 trends generally still hold true today
with a couple exceptions
 Can you think of any?
Fig. 2-1: This cartogram displays countries by the size of their population rather than
their land area. (Only countries with 50 million or more people are named.)

2/3rds of people are clustered in 4 regions
 East Asia (E China, Japan, Korea, Taiwan)
 South Asia (India, Pakistan, Bangladesh, Sri Lanka)
 Southeast Asia (Indonesia, Papua New Guinea, Philippines)
 (Western) Europe (includes 48 countries)
 1/3 of world lives in India or China!

Even though population distribution is
uneven, it is far from irrational
Ecumene – permanently inhabited areas of
earth’s surface
Fig. 2-2: World population is very unevenly distributed across the Earth’s surface
and it can be compared to climate distribution.

75% of world’s population lives on 5% of
Earth’s surface (environmental determinism)
 Dry Lands – deserts, unable to grow crops
 Wet Lands – near equator
 Cold Lands – near poles
 High Lands – mountains


Humans have always been spread very
unevenly across the E’s surface
Even as pop. exploded from 1.5 billion to 6.5
billion in only 100 yrs the areas of pop.
concentration simply became more highly
concentrated (denser) & most of the
uninhabited land remained uninhabited


Arithmetic Density (pop. or crude): total #
of people divided by total land area
Physiological Density: # of people
supported by a unit of arable land
▪ Higher the #, more ppl need to be fed on the crops grown

Agricultural Density: ratio of # of farmers to
the amount of arable land
▪ MDCs have low #’s b/c of technology & finance
Egypt
 Population: 73.3 million
 Pop. Density: 190/sq.mile
 Physiological Density: 6319/sq.mile
 98% of Egyptians live on 3% of the country’s land
Switzerland
 Population: 7.4 million
 Pop. Density: 465/sq.mile
 Physiological Density: 4710/sq.mile
 Mountainous landscape
Ukraine
 Population: 46.7 million
 Pop. Density: 200/sq.mile
 Physiologic density: 381/sq.mile
 Vast farmlands
