 Ecumene: areas
of permanent human
settlement
• Temperate climate regions, land suitable for farming,
concentrated around water sources

Nonecumene – areas not permanently settled: deserts,
polar regions, tropical rainforests, high mountains.
Fig. 2-3: The ecumene, or the portion of the
earth with permanent human
settlement, has expanded to cover
most of the world’s land area.
 75%
live on just 5% of the Earth’s surface,
and almost humans all live on about 20%
of the Earth’s surface
 90%
of world population lives north of
the Equator
 66%
lives in mid-latitudes (30-60o)
 66%
of world population lives within 300
miles of a coast

75% live on just 5% of the Earth’s surface, and
almost humans all live on about 20% of the Earth’s
surface


East Asia: Japan, China, Taiwan, South Korea
• 1/5 of world pop here, 2/3 of China in rural areas, ¾ of
Japan/Korea in cities

South Asia: India, Pakistan, Bangladesh, Sri Lanka (2nd largest
concentration)
• 1/5 of world pop here–mostly rural, though highly concentrated
urban centers

Europe
• 1/9 of world pop here– less than 20% farmers, most food
imported despite excellent climate (3rd largest
concentration)

SE Asia(Islands in between Indian and Pacific Oceans) (4th
largest concentration)
• Comprised of mainly farmers in rural areas

NE US and Canada
• “Megalopolis” from Boston, MA to Baltimore, MD

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.)
• Arithmetic Density: total # of objects in an area
• Physiological Density: # of persons per unit of
arable land
• Agricultural Density: # of farmers per unit of
farmland
Fig. 2-4: Arithmetic population density is the number of people per total land area.
The highest densities are found in parts of Asia and Europe.
Fig. 2-5: Physiological density is the number of people per arable land area. This
is a good measure of the relation between population and agricultural
resources in a society.
