Changing Population - Paper 2 Flashcards
Factors affecting how population varies between places (5)
- Economic opportunities
- Quality of life
- Geographic factors
- Government policies
- Social and cultural factors
What is population density?
The number of people living in a given area
Population/area = people/Km2
What is population distribution?
The location of people within an area
What is a megacity
A city with more than 10 million inhabitants
What is the core and the periphery
Core - the more developed part of a country
Periphery-the less developed part of the country
Name 4 disadvantages of megacities
Any 4 from:
-Overpopulation
-housing shortages
-negative environmental impact
-increased risk of disease
-social inequality
-Strain on healthcare/ education/ services
-Lack of land
What is gross national income per capita formula
the value of a country’s goods and services divided by the number of people living in that country
Give three physical reasons for global distribution and why
- Relief and landforms
The shape and elevation of the land affects the accessibility, soil quality, drainage and natural hazards of an area - Climate and weather
Temperate climates with stable weather conditions are more attractive for settlements - Soil types and quality
Volcanic areas can be highly attractive due to the fertile soil and resources and minerals (sulphur, gold, diamonds etc.) brought to the surface for economic activity
and flat land is attractive for building settlements and easiest for agricultural activities
Why is India and China more populated
-Historical and cultural factors
-large land area
-high birth rate and improved healthcare
-economic opportunities
Name three human factors that determine population distribution
-Economic opportunities
-the standard of living (access to services)
-government policies (political stability)
Look at ESS flashcards to study DTM in ‘Human resource and use’ topic because honestly i cba to rewrite the whole thing here, as the topics overlap
:)
Name two contrasting examples of an uneven population distribution and explain them
France- 67 million
People live in Paris or on the coast/near other major cities. It has a major sphere of influence pulling people to the area. Very few people live in the mountains and external migration is from elsewhere into Paris, whereas internal migration is a way from Paris to the coast
Ethiopia- 105 million
People live near the mountains (cultural factors) and the capital city of Addis Ababa. To the east is dry and barren land with a little population
In France why are the majority of the population located near Paris or the coast
Paris-
Job opportunities
City life
Tourism
The coast -
Water source
Tourism
Agriculture
Warm
Trade
Why are most people located in the mountains in Ethiopia
Most people live in mountainous regions in Ethiopia because it is more hospitable than deserts, there is more rainfall for agriculture, there are more transport links along the river for more business and it is the source of the Nile
Name as many factors as you can that affect natural increase, fertility rate, life expectancy and population structure
-Healthcare
-access to contraception/women empowerment
-migration
-war
-natural disasters (disease)
-the wealth of the country
Name two contrasting countries (case study) that are examples of the processes of population change
-Chad
-Italy
Explain how the age/sex pyramids for Chad differ to Italy
-Chad
Chad’s age/ sex pyramid shows a youthful population in stage two. It has a high birth rate and a high death rate showing hardly any change to the structure over time and a short life expectancy
-Italy
However, Italy’s age/sex pyramid shows an ageing population in stage five with a very high life expectancy. This is because of a low birth rate and a low death rate causing the overall population to slow down
What is the total dependency ratio formula
(Population 0-14+population 64 >) / (working age population 15-64) x 100
What is the child dependency ratio formula
Population 0-14/working age population 15-64 x 100
What is the old age dependency ratio
Population 64>/working age population 15-64 x 100
What is the dependency ratio
The dependency ratio is a ratio between the number of dependents (0-14 and above 64) versus the number of independents (working age)
What does a high dependency ratio mean
The higher the ratio the greater the number of dependents
