Study Notes
Early Demographic Studies
- Early statistical studies by demographers like John Graunt focused on mortality rates and the demographic characteristics of populations.
- Concept of "vital statistics" emerged in the 19th century, encompassing birth and death rates.
Omitted Factors in Early Studies
- Early studies did not initially consider fertility rates as a demographic factor.
Data Collection Methods
- Demographers primarily gather data through census, surveys, and vital records.
Fertility Termination in the U.S.
- The most prevalent means of terminating fertility in the United States is through sterilization procedures.
Sterilization Measures in India
- Quasi-coercive measures to encourage sterilization were used in India during the late 1970s.
Fertility Control Factors
- A significant factor affecting fertility differences in societies with low fertility control is education and access to reproductive health services.
Comparing Mortality Levels
- Overall human mortality levels can best be compared using age-specific death rates and life expectancy indices.
Mass Migration Causes
- One primary reason for the mass migration wave from eastern and southern Europe in the 1880s was economic hardship and the search for better employment opportunities.
Marriage Rates and Gender Imbalance
- Scarcity of males in a given age group generally leads to decreased marriage rates due to competition for available partners.
Social Conventions in Marriage
- Social conventions dictate that males tend to be slightly older than their spouses at marriage to establish status and stability.
Population Pyramids
- Population pyramids are used by demographers to visualize age distribution and analyze population growth patterns.
Declining Death Rates in Developing Countries
- Declines in death rates during stage two of developing countries are due to improvements in healthcare, nutrition, and sanitation.
Agricultural Improvements
- Enhanced agricultural practices, such as crop rotation and irrigation, contributed to food supply improvements in stage two of developing countries.
Public Health Improvements
- Significant public health improvements prior to the mid-20th century included sanitation advancements, vaccination programs, and control of infectious diseases.
Emergent Variables in Health
- A combination of public health education programs and advances in medical technology emerged in the late 19th and early 20th centuries, contributing to declining death rates.
Population Growth vs. Food Supply
- The term "Malthusian crisis" describes the situation where population growth exceeds the available food supply.
Preventive Measures
- Preventive measures to balance population growth and food supply include family planning and contraceptive access.
Critique of Malthusian Theory
- A main criticism of Malthusian theory is its failure to account for technological and agricultural advancements that increase food production.
Positive Checks on Population Growth
- Adverse events considered positive checks on population growth include famine, disease, and wars, which naturally reduce population size.
