Study Notes
China's One-Child Policy
- Introduced in 1980
- Limited most families to one child
- Aimed to control population growth
- Slowed down population increases but led to problems like gender imbalances, an ageing population, and a shrinking workforce
- Ended in 2015, allowing families to have two, and later three, children
Population Density
- The amount of people living in an area of land per km².
- Calculated by dividing total population by total land area.
- Influenced by factors like water supply, climate, relief (shape of the land), vegetation, soils, availability of natural resources and energy, and social, political, and economic factors.
Factors Affecting Population Density
- Availability of Freshwater: Essential for drinking, sanitation, and farming. Areas with abundant freshwater can sustain larger populations.
- Communications (Roads, Railways, Airports): Vital for moving people and goods. Efficient transportation helps access resources, markets, and job opportunities.
- Proximity to the Coastline: Provides access to marine resources and trade routes. Economic activities like fishing and tourism thrive in coastal regions.
- Cities and Their Opportunities: Offer better access to jobs, education, and healthcare. Urban areas typically attract people seeking improved living standards.
- The Shape (Relief) of the Land: Flat or gently sloping land is easier to farm and build on. Terrain affects infrastructure development and industry types.
Population Distribution
- Where people are living and how spread out or close together they are.
- Densely populated areas have many people in a small area.
- Sparsely populated areas have few people in a large area.
- Sparsely inhabited areas often face challenges due to harsh climates or limited resources.
- Habitable environments, such as Western Europe and the United States' East Coast, have favorable climates, flat relief, and an abundance of natural resources.
Push and Pull Factors
- Push factor: A reason or condition that drives people to leave their home country.
- Pull factor: A factor that attracts individuals to migrate to a certain place.
- Immigration: People moving to a country.
- Emigration: People moving out of a country.
Urban and Rural Areas
- Urban areas: Cities or towns with high population density and vast human features.
- Rural areas: Countryside with low population density and more open space.
Antenatal and Pronatal Policies
- Antenatal policies: Programs to support pregnant women before birth, focusing on health and well-being.
- Pronatal policies: Strategies to encourage more births by the government.
Population Pyramid
- A chart that shows the age and gender distribution of a population.
- A broad base with many younger people indicates a growing population.
- A narrow base with more older people typically reflects an ageing population.
Income Levels
- Low-Income Countries: GNI per capita of $1,145 or less.
- Lower-Middle-Income Countries: GNI per capita between 1,146and1,146 and 1,146and4,515.
- Upper-Middle-Income Countries: GNI per capita between 4,516and4,516 and 4,516and14,005.
- High-Income Countries: GNI per capita of $14,006 or more.
