Chapter 1- Population Dynamics Flashcards
What do some people fear will happen to the world?
It will become overpopulated
In the 1960’s, population in most counties was rising. But in the 1970’s it began to fall. Why?
People in MEDC’s had less children than were required to keep the population stable
What large countries have a falling population?
Sweden

Japan
What is birth rate?
The amount of babies born per 1000 people every year
What is death rate?
The number of deaths per 1000 people every year
What is natural increase?
The number of people added to or lost from the population per 1000 every year- the difference between birth rate and death rate
How is natural increase calculated?
(Birth rate - death rate) x100
Positive number- population is increasing
Negative number- population is declining
More-or-less equal- population is saying the same
(Note: natural increase is normally a percentage)
Why do birth and death rates vary from place to place?
The development of a country
The religious views i.e. contraception
The view of the government
Where is the:
1) Population increasing
2) Population balanced
3) Population decreasing

3) Russia, Central and Eastern Europe
In what type of countries is high levels of population increase common?
Developing LEDC’s with low to middle income
In what type of countries is low levels of population increase, balanced population and even population decline common?
Developed MEDC’S with high income
Why does population increase?
People have more than 2 childen-babove replacement rate
People are poorly educated- no contraception
LEDC families need farm workers- children
