Distribution
the pattern of people across the earth’s surface
Density
the number of people in a particular land area
Concentrated
highly density populated
Dispered
low density population`
Arithmetic Denstiy
the total number of people divided by the total land area
FOR EXAMPLE, If 4.4 million people live in Minnesota, the area of which is 84000 square miles, this means Minnesota has an arithmetic density of…
52 people per square mile
Physiological density
Population divided by arable (farmable) land
An example of physiological density is if the physiological population density of the u.s. is 340 people per square mile in Japan’s is 7000 people per square mile, this indicates the arable land in Japan is scarce, given the country’s population and land resources.

carrying capacity
the number of people the area can sustain/support
The higher the population density…
the more CC is needed
infrastructure
support systems: housing, police force, road system, education. food supplies and health care
Governments and societies constantly try to develop their ______ to expand their carrying capacity
infrastructure
EXAMPLE OF CC: Despite Israel’s dry climate, it has developed advanced irrigation methods to create more arable land to increase its farming output. This innovation has increased its carrying capacity despite the land area.

Example of population distribution impacting on society and politics… in areas of high population density, politicians and policymakers are likely focused on issues such as maintaining sustainable growth, fixing infrastructural stains: like traffic, and improving efficiency of services to meet the needs of Highly dense areas.
