Study Notes
Population Distribution
- Population distribution maps show where people live, with high concentrations in places like India, China, and Indonesia.
- Natural resources, socioeconomic factors, political decisions, and accessibility influence population distribution.
- People tend to settle where resources are abundant, avoiding deserts.
- Economic opportunities and gender roles in society affect where people live.
- War or government policies can cause population movements.
- Areas with better transportation links attract more people.
Analyzing Population Pyramids
- Population pyramids show a region's demographic characteristics.
- They reveal information about dependency ratios, birth and death rates, gender makeup, life expectancy, economically active populations, and population growth.
- A high death rate indicates a larger population of elderly individuals, especially in later stages of the demographic transition model.
- Larger middle sections of the pyramid reflect a healthier economy.
Shapes of Population Pyramids
- Population pyramids come in three main shapes, each indicating different developmental stages.
- Triangle shape: Characterizes developing nations with high birth rates and low life expectancies, resulting in rapid growth (e.g., Niger, Afghanistan).
- Rectangle shape: Represents developed countries with stable population growth and higher life expectancies (e.g., United States, France).
- Inverted pyramid shape: Found in countries with aging populations, leading to negative growth (e.g., Japan, Germany).
Real-World Examples
- Namibia has a developing nation population pyramid with high birth rates and low life expectancies.
- The United States has a stable growth pyramid with an almost equal number of infants and older adults.
- Japan's inverted pyramid reveals challenges related to an aging population.
The Demographic Transition Model
- The demographic transition model describes four stages of societal evolution linked to livelihood activities that impact birth rates, death rates, and overall populations.
Stage One: Pre-Modern Societies
- Hunter-gatherer phase, lasting about half a million years.
- Nomadic lifestyles and reliance on nature.
- Extremely high and erratic birth and death rates due to environmental factors.
- Low total population.
- High fertility rates for survival, with high infant mortality rates.
- Stage One societies are mostly gone, with some indigenous groups remaining in remote areas.
Stage Two: Urbanization and Industrial Phase
- Transition to agriculture, settled farming, and then industrial work, spanning over 8,000 years.
- Stable high birth rate, but a significantly declining death rate due to better food supply, technology, and healthcare advancements.
- Explosive population growth as death rates plummet and birth rates stay high.
Understanding Population Growth
- Population growth is largely attributed to improved infant survival rates rather than increased birth rates following the Industrial Revolution.
- Case studies of countries with different stages of population change illustrate the factors influencing shifts.
Current Population Trends
- Understanding population dynamics informs resource management and economic stability.
- Rapid population growth in some countries.
- Potential population decline in countries with low birth rates and aging demographics (stage five of the DTM).
Epidemiologic Transition (ET)
- It's not the same as the DTM, but it helps identify stages of illnesses/threats within each stage of the DTM.
Stage 1 (ET)
- Large-scale famines and epidemic diseases.
- Low life expectancy.
Stage 2 (ET)
- Reduction of major illnesses.
- Sanitation and hygiene education.
- Decreased spread of diseases.
Stage 3 (ET)
- Decreased odds of getting sicknesses.
- Human-created diseases (heart attack, cancer, etc.).
Stage 4 (ET)
- Degenerative diseases still exist.
- Medical advancements.
Stage 5 (ET)
- Re-emergence of infectious and parasitic diseases.
- Poverty.
- Eradicated diseases.
- Pandemics through relocation diffusion (e.g., AIDS, Ebola).
Dependency Ratio
- The number of non-working age individuals divided by the number of people aged 15-65.
- Stage 2 countries have many young people under 15.
- Late stage 4 countries have a higher proportion of people over 65.
- Stage 1 & 2: High youth dependency, low elderly dependency.
- Stage 3: Decreasing youth dependency, low elderly dependency, overall balance.
- Stage 4 & 5: Increasing elderly dependency, very low youth dependency, overall high dependency ratio due to an aging population.
Replacement Rate
- The total fertility rate (TFR) needed to maintain a stable population is 2.1.
Eugenic Population Policies
- Favor one racial or cultural sector over another.
- Started in the United States.
- Examples: Holocaust.
Migration
- Population rises in developed countries due to net-in migration (more people coming in than leaving).
- Population rises in developing countries due to net-out migration (more people leaving than coming in).
- Reasons for migration: better conditions, overpopulation, war, famine, political instability.
Ethnic Enclaves
- Neighborhoods or communities within larger regions predominantly inhabited by a particular ethnic group.
Cultural Reasons for Migration
- Religion, beliefs, oppression of ethnicity, race, sexual orientation.
- Forced or voluntary reasons.
Economics as a Driving Force for Migration
- The leading reason people move to or within countries, seeking more job opportunities.
Cyclic Movement
- Movement away from home for a short period (e.g., commuting, regular trips).
Periodic Movement
- Movement away from home for a longer period (e.g., migrant labor, transhumance, military service).
Interregional Migration Trends
- Canada's interregional migration follows an east-to-west trend, similar to the US.
- Russia shows a reversal of this trend.
- China's population is moving to larger coastal areas.
- Rural-to-urban migration is prominent in India.
Population Policies (Example: Germany)
- Germany has accepted many refugees in the later 20th century.
High Physiological Density
- Pressure on land to produce enough food.
- Small amount of arable land, large population.
High Agricultural Density
- Suggests heavy manual labor and a lack of modern technology.
- Small number of farmers, large amount of arable land.
High Arithmetic Density
- Large population living in a small area.
- Issues with overcrowding, competition for resources, and infrastructure strain, especially in urban areas.
Sex Ratio
- The standard biological sex ratio at birth is 105:100 in developed regions.
- It's 112:100 in China and India, suggesting a lower percentage of female newborns.
Maternal Mortality Rate
- High in Africa and Asia, exceeding 100 deaths per 100,000 mothers.
- Lower than 10 in most European countries.
Intraregional Migration
- People moving from rural areas to suburban areas.
Stages of Migration Transition
Stage 1: Pre-Industrial Societies
- Little migration, mostly subsistence farming.
- Local movements driven by immediate needs, like environmental changes or resource availability.
Stage 2: Early Industrial Societies
- Significant internal migration from rural to urban areas for jobs, driven by industrialization and urbanization.
- Increased international migration from less developed countries to more developed ones for economic opportunities.
Stage 3: Mature Industrial Societies
- Internal migration continues, but shifts from rural-to-urban to urban-to-suburban for better living conditions.
- International migration continues, but with more diverse patterns, including immigration from both developing and developed countries.
