Distribution - geographers are concerned about the arrangement of features on the earth’s surface.
3 main properties of distribution are:
Density - the
frequency that something occurs in a given space.
Concentration - changes
in distribution-how close together-dispersed or clustered.
Pattern - the
arrangement of the distribution of features in a given space.

DISTRIBUTION:
Density and Concentration
Density
: “How many per?”
Concentration
: “How spread out?”
Major League Baseball
Density
1952: 16 teams
2012: 30 teams
Concentration
1952: All Eastern US
2012: Most regions of the US and in Canada

– The region from which innovative ideas originate

Example: Early cultural hearths
Nile River
Indus River
Mesopotamia
Modern Examples:
-Facebook and Harvard University
-Surfing and HawaiiSlide14Slide15Slide16
Expansion diffusion
Culture/Ideas spread throughout a population from area to area.
Subtypes:
a. Hierarchical diffusion
: ideas leapfrog from one node to another temporarily bypassing some
b. Contagious diffusion
: wavelike, like disease
c. Stimulus diffusion
: specific trait rejected, but idea accepted
Relocation diffusion
occurs when individuals migrate to a new location carrying new ideas or practices with themSlide17
Hierarchical Diffusion
Hierarchical
diffusion – The spread of a feature or trend from one key person or node of authority or power to other persons or places
.
Large cities
small cities small towns
Important people down the social hierarchy
Examples:
Hip-hop/rap music
Fashion trendsSlide18
Wal-MartSlide19Slide20
Contagious Diffusion
Contagious
diffusion – The rapid, widespread diffusion of a feature or trend throughout a population
.
No hierarchy, spreads by contact
Examples:
Disease
Information on the internetSlide21
AIDSSlide22Slide23
Stimulus Diffusion
Stimulus
diffusion – The spread of an underlying principle, even though a specific characteristic is rejected
.
Spread of a concept, with a twist
Examples:
Early computers
Surfers
skateboarders snowboardersSlide24
Relocation Diffusion
Relocation
diffusion – The spread of a feature or trend through bodily movement of people from one place to another
.
People move, they bring things with them (culture, language, religion, etc.)
Examples:
Euro coins
Religion with migrating settlers
Slave TradeSlide25
