Population Density And Distribution Flashcards
What is population density
This is a measure of a how many people live in a set area
How is population density calculated
Number of people divided by area in square kilometres
An area that has a high population density will have what
Lots of people living in that space
An area that has a low population density will have what
Few people living in that space
Places that have a high population density are said to be what
Densely populated
Places that have a low population density are said to be what
Sparsely populated
Examples of sparsely populated spaces
Greenland Siberia Antarctica Australian outback Sahara desert
Examples of densely populated places
New York Rio de Janeiro Hong Kong Cairo London
Why do cities tend to be densely populated
Due to the fact that there are a lot of people in an area that is limited in size
London has a population desire of what
4700 people per square kilometre
Glasgows population density is what
3494 people per square kilometre
Why is the population density for the uk lower than its major cities
Because there is more room for people to spread out
What do density figures only tell us
How many people live in n area
What is population distribution
Population distribution describes how people are distributed or spread in a certain area
How many ways can we describe population distribution
3
What is the first way we can describe population distribution
The population can be evenly spreaded
What is the second way we can describe population distribution
The population can be clustered around one specific location
What is the third way we can describe population distribution
The population can be randomly distributed
Often distribution of the population is effected by what
Factors of physical and human geography
Why are parts of the world more densely populated than others:
Amazon rainforest
Too hot and wet for people
Dense forest makes communication and settlement difficult
Sparsely populated
Why are parts of the world more densely populated than others:
Western Europe
Low lying and gently sloping Pleasant climate Good water supply and soil for farming Easy communication and many resources for industry Densely populated
Why are parts of the world more densely populated than others:
Himalayan mountains
Too cold for people
Steep slopes and bad for communication and settlement
Poor thin soil, unsuitable for crops
Sparsely populated
Why are parts of the world more densely populated than others:
Polar regions - Antarctica
Too cold for people
No soil for crops
Snow and ice make communications and settlement very difficult
Sparsely populated
Why are parts of the world more densely populated than others:
Bangladesh
Low lying and flat rich fertile soil. Hot and wet, ideal farming conditions. Densely populated
Give a reason why some parts of the world are more densely populated that others
Climate - places that are too hot, too cold or too wet, or too dry - don’t attract people to live there because it is hard to grow crops
Physical factors:
Good food supply Poor soil for farming Flat gently sloping land - easy to build on Too wet or too dry - difficult to farm Too hot or too cold - difficult to farm Steep slopes - hard to build on Etc etc etc
Human factors
Money for investment Industry and jobs Poor transport Lack of investment Good roads, railways, ports etc Little investment and few jobs
Positive factor
Natural resources for industry Money for industry Good food and water supply Good soil for growing crops Industry and jobs Good roads, railways, ports etc Open grassland for animals Pleasant climate Flat/gently sloping land
Negative factor
Poor transport Lack of investment Little investment and few jobs Poor soil for farming Steep slopes Too wet or too dry Few natural resources Too hot or too cold
What is the definition for worlds population
The total number of humans alive on Earth at a given time
What is happening to the worlds population rapidly
It is increasing
Every second how many people are born and how many die
5 are born
And 2 die
That is a gain of 3 people per second
