Where is the world population distributed?

3. Examining the distribution of humans across the planet is one of the most fascinating elements of Human Geography.
DEMOGRAPHY- the study of statistics, location, structure of human populations.

4. FIGURE 2-8 WORLD POPULATION THROUGH HISTORY Through most of human history population growth was virtually nil. Population increased rapidly beginning in the eighteenth century.

5. HUMANS ARE NOT EVENLY DISTRIBUTED
Population Concentrations
2/3 of the world’s inhabitants are clustered in four regions of the globe.

21. One of the deepest divisions in the world today exists between URBAN and RURAL places and people.
The world is rapidly urbanizing- but that can mean very different things to different people.

22. The URBANIZATION Divide
All 3Asian clusters are more than 50% rural, on average- most are small farmers working on small plots.*
Europe is more than ¾ urbanized. It is supported by very few farmers, who use technology to work large plots.
*Japan is an exception, resembling Europe.

23. Site and Situation of Population Clusters
Mostly low-lying areas with fertile soil and temperate climate
Near an ocean, or near a river with easy access to an ocean.

24. Regions hosting permanent human settlement are called the ecumene zone.
FIGURE 2-3 POPULATION DISTRIBUTION People are not distributed uniformly across Earth’s surface.

25. The ECUMENE has grown larger as humans have dispersed across the Earth,
and as technology and innovation have allowed us to adapt to new environments.
FIGURE 2-4 ECUMENE Seven thousand years ago humans occupied only a small percentage of Earth’s land area, primarily in Southwest Asia, Eastern Europe, and East Asia. Even 500 years ago much of North America and Asia lay outside the ecumene. Still, approximately three-fourths of the world’s population live on only 5 percent of Earth’s surface.
The balance of Earth’s surface consists of oceans (about 71 percent) and less intensively inhabited land.

26. Sparsely Populated Regions
Humans avoid clustering in certain physical environments.
Dry Lands
Wet Lands
Cold Lands
High Lands
Humans tend to avoid places that are unaccommodating for activities, such as agriculture. Among these are places with too much or too little available water, places with exceedingly hot or cold temperatures, and places that have too steep of slopes to plant crops.

27. Regions which were once inconceivable for settlement have become part of the Ecumene.

30. MEASURING POP’N DENSITY
There are THREE primary ways geographers measure population density.

31. Population Density Arithmetic Density
Density of people in a given area
Equation: Divide the total population by the total land area
Physiological Density
Number of people supported by a unit area of arable land
Equation: Divide the total population by total arable land area
Agricultural Density
Ratio of the number of farmers to amount of arable land
Equation: Divide # of farmers by total arable land area
Physiological density provides insights into the relation between the size of a population and the availability of resources in a region.
Developed countries have lower agricultural densities, because technology and finance allow a few people to farm extensive land areas and feed many people.
