Section 1: Where Is Everyone?
What is demography?
Create your own definition:Demos (Greek for “People”) + graphe
(Greek for “to describe”)
What is population distribution?
“Population distributions are descriptions of locations on the Earth’s surface where individuals or groups live.”
In what places on Earth do you expect to find the most people living?
What common traits might these places exhibit?
What is ecumene?
“Ecumene is the portion of the Earth’s surface occupied
by permanent human settlement.”
Common Traits of Ecumene
Almost 90% of all people live north of the
equator.
More than half of all people live on about 5% of the land, and
almost nine-tenths on less than 20%.
Most people live in areas close to sea level.
About two-thirds of world population is concentrated within
300 miles of the ocean.
How do you measure population?
“You measure population by looking at Population Density;
the number of people occupying an area of land.”
• The total number of people in an area.• Population divided by Land Area
Arithmetic Density
• The number of people supported by a unit area of arable land.
• Provides insights into the relationship between the size of a population and the availability of resources in a region.
Physiological Density
• The ratio of the number of farmers to the amount of arable land.
Agricultural Density
Discuss how the agricultural density of the United States may have changed over the last 200 years.
