Study Notes
Reasons for Rapid Population Growth
- Improved medical care: vaccinations, hospitals, doctors, new drugs, and scientific inventions
- Improved sanitation and hygiene, and water supply
- Improvements in food production (quality and quantity)
- Improved transport: moving food, doctors, etc.
- Decrease in child mortality
- Decline in tribal wars
Population Growth Terms
- Migration: movement of people (or animals) from one country or region to another
- Birth rate: average number of live births in a year for every 1000 people
- Death rate: average number of deaths for every 1000 people
- Carrying Capacity: the number of people the environment can support without negative effects
- Optimum Population: the amount of people a region/country can ecologically support, usually less than carrying capacity
- Under-population: when a country has declined too much that it can't support its economic system
- Overpopulation: too much population of an area, leading to overcrowding, depletion of resources
Effects of Population Growth on the World
Environmental Impact
- Depletion of Resources: overexploitation of natural resources, depletion of water tables
- Deforestation, loss of biodiversity, air and water pollution, and climate change
Social Implications
- Pressure on Healthcare and Education: increasing population puts pressure on healthcare systems and educational institutions
- Economic Effects: population growth can stimulate economic growth, but can also lead to unemployment, poverty, and income inequality
- Social Implications: population growth can impact family structures, cultural norms, and social cohesion
Economic and Infrastructure Effects
- Pressure on Infrastructure: increased population puts pressure on transportation networks, utilities, and communication systems
- Economic Effects: population growth can lead to economic growth, but also strain economic resources
- Global Migration: population growth can drive migration, leading to social and political challenges
Factors Influencing Population Growth
- Natural change: difference between birth rates and death rates
- Net migration: balance between immigration and emigration
Factors Encouraging High Birth Rate
- Early marriages: in some countries, people marry as young as 15 years old
- Children are seen as wealth: in some Asian countries, children are a source of economic support
