Human Geography - Population Flashcards
How do you calculate population density?
It is calculated by dividing the total population by the size of the area
What is population distribution?
It refers to the way in which people are spread in any given area. It is uneven and changes over time
What physical factors influence where we live?
Climate, natural resources, water supply, natural routes, relief, vegetation and soil
What is birth rate?
The number of babies being born each year per 1000 people in the total population
What is death rate?
The number of people that die each year per 1000 people in the total population
When does a natural increase in the population occur?
When the birth rate is higher than the death rate
When does a natural decrease occur in a population?
When the death rate is higher than the birth rate
Why does the populations stay the same?
The birth rate and death rate are roughly the same
What is the population growth rate?
The speed at which the population increases
How birth and death rates measured?
The number of births and deaths for each 1000 of the population
What was the growths like in the population between 1750 and 1900?
The worlds population grew slowly to reach over 1 billion by 1900
What happened in the 20th century to the worlds population?
There was a population explosion when population grew from just over 1 billion to over 6 million in 2000
What is the population growth rate estimated to be like in the future?
In the future, population is projected to continue to grow to about 9 billion by 2050 so the population will continue to increase but at a slower rate
What three factors control the size of a population?
Birth rate, death rate and migration
What is an immigrant?
Someone who is entering a geographic area
What is an emigrant?
Someone who is leaving a geographic area
How is net migration calculated?
The difference between the immigrants and emigrants
Why did the population grow so rapidly in developed countries during the industrial revolution?
The death rate began to fall because new technologies and increasing industrialisation improved public health and living standards. Also, new farming and transportation technology expanded the food supply and lessened the danger of famine. Finally, people could plan having families with available contraception.
What is total fertility rate (TFR)?
The number of children woman is having today (UK 2007 is 1.8)
In which climate region are people most likely to be found?
Warm / cool temperate forest
Name some densely and sparsely populated areas in the world
Densely populated: Sydney, Etna, north-west Europe, New York and Bangladesh
Sparsely populated: Afghanistan, North East Brazil, Greenland, Iraq and Rwanda
What is population density?
Population density is a measurement of the number of people in an area (usually per sq km). It is an average number
