GEO - Population Flashcards
What is population explosion?
- A rapid increase in the global population
- This has happened over the past century.
What caused population explosion?
- Better healthcare that leads to lower death rates
- Better farming practices & technological advancements.
These factors significantly increased life expectancy and reduced infant mortality, resulting in a dramatic rise in population numbers.
What 3 factors cause population growth
- Birth rate
- Death rate
- Migration
How does birth rate impact population
High birth rates cause to population growth.
Low birth cause to population decline.
How does death rate impact population
Lower death rate due to better healthcare and living conditions, contribute to population growth.
How does migration impact population?
Immigration increases population, while emigration decreases it.
What is relationship between population and resources?
Over-population occurs when there are too many people for the available resources, leading to shortages and environmental impact.
Under-population happens when there are too few people to use the available resources efficiently, which impacts economic growth and development.
What is the impact of a Youthful Population?
A population with a high number of young people causes challenges in providing education and healthcare
Also an opportunity for future economic growth.
What is the impact of a Aging Population?
A high number of elderly people can strain healthcare and pension systems but can also provide opportunities for experienced labor and volunteering.
What are the 3 factors that influence population distribution?
Physical factors (climate, terrain, water availability)
Human factors (cultural, social, and political factors)
Economic factors (employment opportunities, infrastructure).
Where do you find dense populations?
Fertile land
Urban areas
Good climates,
Where do you find sparse populations?
Deserts
Mountains
Extreme climates.
What is Rural-Urban Migration?
Movement from rural areas to cities within a country, often driven by the search for better job opportunities and living conditions.
What is International Migration and what causes it?
Movement between countries
Either voluntary (seeking better opportunities) or involuntary (escaping conflict or persecution).
How does high GDP affect population
Higher GDP often leads to better living standards and access to healthcare
This lower mortality rates and increase life expectancy.
Higher GDP can also correlate with lower birth rates as people may choose to have fewer children.
How does cost of living affect population?
People choose to have fewer children due to financial constraints.
Lower birth rates and slower population growth.
How does disease affect population?
A lot of diseases like AIDS can impact population growth by increasing mortality rates, especially in regions with limited access to good medical care
How does disease affect population?
Religious beliefs and practices can influence population growth.
Some religions encourage larger families or not believe in contraception, which can increase birth rates
How does Government Policy affect population?
Policies such as China’s former one-child policy or incentives for larger families can directly affect population growth rates.
Government programs that improve healthcare and education also impact population dynamics by influencing birth and death rates.
What is GDP
Gross domestic product is the monetary value of all finished goods and services made within a country during a specific period.
What is DTM
Demographic Transition Model
