Population Flashcards
Demography
Study of population
How do we calculate population change
We calculate population change by measuring death rate vs birth rate
When the birth rate is higher than the death rate the population…
Increases
When the death rate is higher than the birth rate the population…
Decreases
Population Cycle
Stage 1
High fluctuating
High birth + death rates. Population can fluctuate/grow very slowly
Eg.Somalia
Population cycle
Stage 2
Early Expanding
High Birth rates falling death rates. Population grows very quickly
Eg.Nigeria
Population Cycle
Stage 3
Late expanding
Birth and death rates fall. Rate of population grows slowly
Eg.India
Population Cycle
Stage 4
Low Fluctuating
Birth and death rates are low. Population fluctuates + slowly increases
Eg.Ireland
Population Cycle
Stage 5
Natural decrease
Low death rate, lower birth rate. Polyalation in decline. Natural decrease
Ex.Germany
List factors influencing population chamge
Food
Globalisation
War
Education
Place of women in society
Technology
Health
Factors influencing population change
Food
Improving crop production increases population
Poor crop production decreased population
Factors influencing population change
Globalisation
The process where the world becomes interconnected as a result of increased trade + movement of people
People move to new places
Factors influencing population change
War
People are killed in war, increasing the death rate
Partners are separated, decreasing birth rate.
When soldiers return birth increases.
Factors influencing population change
Education
More information helps people make better decisions.
Better education=lower death+birth rates
Poor education=higher desth+birth rates
Factors influencing population change
Place of women in society
More women in the work force=lower birth rstes
