Target A
Life expectancy functions as a key demographic indicator that reveals a population’s overall health and socio-economic development.
Describe each stage of pop. Pyramid
Stage 1- High birth and death rates Low life expectancy, high youth dependency ratio.
Stage 2- High birth rates, falling death rate. Rising life expectancy, high youth dependency ratio.
Stage 3- falling birth rates, low death rates, increasing life expectancy, and decreasing dependency ratio as workforce Expands.
Stage 4- Low birth and death rates, high life expectancy, stable, balanced dependency ratio
Stage 5- Very low birth rate (below death rate), record-high life expectancy but old-age dependency ratio
How voluntary and involuntary migration affect population distribution
voluntary movement often shifts labor and talent toward growing economic hubs, while involuntary migration—driven by conflict or disaster—can rapidly concentrate displaced populations in specific areas, creating sudden imbalances in age, gender, and resource demand.
What is a megacity?
A city with a population of one million or more.
What are pros of pro-natalist policies?
Con?
Pro: Helps grow the labor force, and prevents population decline in aging societies
Con: Can be very expensive, may not address the root causes of why people choose not to have kids, and can sometimes pressure individuals into traditional roles they don’t want.
How does life expectancy give insight to a population?
High life expectancy often signals advanced healthcare and stability, leading to an aging pop. Low life expectancy typically correlates with higher birth rates and younger, rapidly growing pop.
What is youth dependency ratio?
Elderly?
Ratio of people ages 0-15 to the working age population
Ratio of people 65+ to the working age population?
What is voluntary migration and involuntary migration?
Involuntary- Forced migration (no choice) life or death. Ex. War, genocide, persecution, natural disasters, famine drought
Pros and cons of being a megacity? 5 eac
Pros:
- Higher concentrations of economic activity and diverse job markets
- Increased access to specialized healthcare and advanced education institutions.
- Greater cultural diversity and social connection
-More innovation due to close Proximity to resources and more people
Cons:
- High Levels of pollution and environmental degradation
-Intense pressure on housing leading to high cost and overcrowding
-Inceased risk of traffic congestion and infrastructure strains
-Higher crime rates -Lack of resources
-Higher spread of disease
Pros and cons of anti-natalist policies?
Pros: helps reduce strain on limited resources, can lower poverty rates by allowing families to focus resources on fewer children, and improves maternal health
cons: often results in severe gender imbalances, and can lead to human rights violations if implemented through force
- Asia is the most populated continent
-China and India are the most populated countries
-Middle income countries are most populated.
-Subsaharan Africa is the fastest growing continent.
—People tend to live in lower elevation areas and areas in the mid latitude with conditions ideal for farming.
- People tend to live near bodies of water, on the coast.
What are pull factors and examples?
What are push factors and examples?
1.) All the factors (speed) that cause a migrant to go to a destination place (what attracts them) Ex. Job opportunity, education, marriage.
2.) All the factors (speed) that cause a migrant to leave their origin place to go elsewhere ex. War, gov. Corruption, bad economy
What is internal migration, external migration, and circular migration?
Internal migration- Migrating within the country ex. Virginia to georgia
External - Migrating outside of the country ex. Ghana –> Nigeria
Circular migration: From origin to destination back to origin
Chonching as a pro?
Dharavi slums is an example of a con of mega cities. Not enough housing so people are being forced to leave in slums (housing becomes expensive so it’s limited, and people can’t afford to live elsewhere)
Chonching as a major manufacturing and automotive hub for western china, leveraging its huge local workforce and helping the economy
What is HDI?
How does it connect to population distribution?
Nations with high HDI typically see lower birth rates and longer life expectancies, leading to stable or aging ppulations, while those with a low HDI often experience higher birth rates and shorter-life expectancies, resulting in rapid, youth-driven population growth
What is MEDC and LEDC, and BRIC? How do they connect to population variations?
MEDC stands for More Economically Developed Country, and LEDC stands for Less Economically Developed Country; BRICS refers to the major emerging economies of Brazil, Russia, India, China, and South Africa. These terms explain how populations vary because economic development directly dictates birth rates, death rates, and age structures—wealthier nations typically have aging, stable populations, while developing ones often have younger, faster-growing populations with higher mortality risks.
IDP: internally displaced person within country, always involuntary, no international law protecting them ex. jews protecting them
Refugee: external, involuntary, has international protection, hope to go back home.
Asylum: Legal protection granted by a country to someone who has fled their home because they are unable or unwilling to return due to a well-founded fear of persecution.
What are pro-natal policies and anti-natal policies?
Pro-natal policies are policies that increase population size and birth rate
Anti-natal policies are policies that limit birth rate and decrease population
What is demographic dividend? What country achieved it? Describe the case study of this country, what stage is it in?
Demographic dividend happens when high birth rates fall, and a country invests in education, healthcare, governance, and economic policy, resulting in accelerated economic growth as the age structure changes.
Korea (stage 3) worked toward demographic dividend. They combatted high birth rates by creating family planning programs to teach women about contraception and encourage birth control. They also modernized it’s economy to from dependency on farming and fishing to more diverse industry (manufacturing, agriculture, etc.)
What stage is japan in? Describe japan’s case study
Japan is in stage 5 with a low birth rate, high life expectancy, decreasing population, and an aging society. Japan had a elderly dependency ratio
To alleviate this, Japan created a nomad visa to increase the immigration of workers but it’s a temporary fix as it wasn’t enough to actually make the total population grow. Also introduced a four-day workweek for gov. Employees, designed to help working mothers and boost birth rate.
Describe the china case study
describe the syria case study
China- primarily internal and voluntary migration. This movement involves a massive rural to urban shift (west to east, non-megacity to megacity) where people from the countryside move to burgeoning cities to seek better opportunities
Syria- Forced displacement and external movement to neighboring countries, people became refugees or IDPS due to push factors like civil war and extreme poverty. Movement by lack Of city and need for basic needs.
What is an effective use of pro-natal policies?
What is an effective use of anti-natal policies?
1.) Ghana’s ”one tree, one child policy” requiring families to plant trees for new childrem, works because it connects having a child to helping the environment. Make starting a family feel like a positive way to contribute to the community’s future.
2.) China’s one child policy - The gov. Forced people to only have one child. While it did lower the birth rate, it caused major problems like an aging population and a shortage of workers, as well as promoting sexist views
