Study Notes

Demographic Transition Theory (DTT)

Developed to explain population changes in the West, it assumes that pre-industrial societies had historically high fertility rates and that mortality rates fell before fertility rates did.
Pre-industrial societies lacked control over their own fertility, and Western medical advancements and contraceptives are seen as the primary means of controlling fertility.
Strengths of DTT: Can be used to predict population growth, inform population policy, and characterize development stages.
Weaknesses of DTT: Ignores migration, assumes a "one size fits all" development model.

The Four Phases of Demographic Transition:

Phase 1: High Fertility/High Mortality:
- Pre-industrial society
- High fertility driven by lack of family planning, high infant mortality, and need for agricultural workers (children as economic assets).
- High mortality due to disease, famine, lack of sanitation and education, and competition for food.
Phase 2: High Fertility/Declining Mortality:
- Developing countries
- Declining mortality due to improved healthcare, sanitation, and food supply.
Phase 3: Declining Fertility/Low Mortality:
- Developed countries
- Declining birth and death rates driven by family planning, lower infant mortality, mechanisation of agriculture, increased standard of living, and improved status of women.
Phase 4: Low Fertility/Low Mortality:
- Post-industrial society
- Modern times

Demography:

Study of population size, growth/decline, distribution, composition (age, sex, race), characteristics, and components of change.
Importance: Informs UN population policy, environmental concerns (climate change, overfishing), politics (electoral math), public planning (roads, infrastructure, zoning, economic development), market research, investment strategies, and business.

Overpopulation Theories:

Thomas Malthus:
- Published "On Population" in 1798.
- Argued population grows geometrically, while food grows arithmetically.
- Believed population growth is dependent on agricultural production.
- Proposed "positive checks" (natural disasters, war, famine, disease) and "moral restraint" (abstinence) to regulate population size.
Ester Boserup:
- Emphasizes that agricultural production is dependent on population growth.
- As population increases, there is pressure to innovate and intensify land cultivation, increasing the carrying capacity.

Fertility:

The production of a live birth.
Proximate Determinants of Fertility: Biological factors influencing how many children a woman will have:
- Conception and probability of conception
- Length of breastfeeding (can delay conception)
- Intercourse
- Successful gestation of a child
Social components of fertility are more significant than biological components.

Policies to Decrease Fertility:

Developing countries: Focus on education, economic prosperity, family planning, control over one's own body, improved workplace conditions, and increased accessibility to abortion.
Key factors to address:
- Age at marriage or intercourse
- Contraceptive use
- Incidence of abortion
- Involuntary infecundity (breastfeeding)

I-PAT Model:

Environmental impact = Population x Affluence x Efficiency of technology
Policy Implications:
- Population Policies: Make abortion more accessible, one-child policies, population control measures.
- Affluence Policies: One-car policy, restricted living space, taxes on carbon emissions.
- Technological Policies: Electric cars, renewable energy sources, AI.

Mortality:

Number or rate of deaths in a given time or place.
Lifespan: Highest age at which a person can live (Jeanne Louise Calmet at 122 years).
Longevity: Realistic average life expectancy.
Infant mortality: Has a significant impact on overall life expectancy, often preventable with basic resources and education.

Theories of Migration:

Migration: Permanent relocation across state boundaries or change in residence.
Reasons for Migration: Job offers, education, family proximity, environmental factors.
Key Theories:
- Neoclassical Economics Theory: Supply and demand dictates migration based on wage differentials.
- New Household Economics Theory: Family/household needs drive migration decisions.
- Dual Labor Market Theory: Developed regions have two job markets, one for the educated and another for the less educated.
- World Systems Theory: Migration is a consequence of global economic and political systems.
- Network Theory: Migrants maintain connections with their countries of origin.
- Institutional Theory: Institutions facilitate and profit from migration flows.
- Cumulative Causation Theory: Previous migration impacts subsequent migration decisions, creating "immigrant" job sectors.

Primary vs. Secondary Data:

Primary Data: Collected specifically for a research purpose, fresh and original data.
- Advantages: Accurate, reliable, up-to-date, addresses specific research interests.
- Disadvantages: Time-consuming, expensive, not immediately available.
Secondary Data: Collected by someone else for a different purpose.
- Advantages: Complements primary data, easily accessible.
- Disadvantages: May be inaccurate, inconsistent, inaccessible.

Sources of Demographic Data:

Vital Statistics: Population processes of life and death.
Census Population: Population, structure, and characteristics.
Administrative Data: Local population changes, mobility, and migration.
