  • Malthusian Times
    Robert Wyman

    Focusing on lineage and family dynamics, this module discusses how cultural beliefs about ancestry shape reproductive strategies in various societies. It contrasts the familial structures seen in pre-modern Sub-Saharan Africa with those in temperate regions.

    Population pressures, high mortality rates, and the cultural necessity for large families to ensure lineage continuation are examined, along with the societal impacts of epidemics and wars that historically shaped demographics.

  • This module investigates the demographic transition in Europe during the mortality decline phase. It analyzes factors that historically limited population growth, such as disease and poor sanitation, and the eventual improvements in public health.

    The Industrial Revolution's role in this transition is emphasized, detailing how innovations in medicine and hygiene contributed to falling death rates and rising populations.

  • This module delves into the fertility decline in Europe, emphasizing the socioeconomic factors that influenced changing attitudes toward childbirth during and after the Industrial Revolution. It explores Malthus's theories on population growth and their relevance in contemporary discussions.

    Students will examine the complex relationship between fertility rates, economic development, and societal norms that led to significant demographic changes.

  • This module covers the expansive demographic transition in Europe, focusing on the cultural shifts that influenced marriage and fertility. It discusses how marriage control evolved, leading to increased fertility rates once contraception became accepted.

    By examining historical patterns of family planning, students will gain insight into how these transitions drastically altered societal structures and population dynamics.

  • Quantitative Aspects
    Robert Wyman

    This module emphasizes quantitative aspects of population data, discussing the challenges posed by politically influenced census data. It contrasts birth rates in developed and developing countries and highlights factors affecting demographic trends globally.

    By examining the implications of age structure on population growth and the concept of 'momentum' in fertility rates, students will understand the complexities of global population stabilization.

  • This guest lecture by Michael Teitelbaum investigates the implications of low fertility in developed countries. It examines the societal challenges posed by aging populations and the potential responses, including immigration and policy adaptations.

    Students will explore how historical views on population growth have shifted and the effectiveness of current strategies to manage fertility levels.

  • This module focuses on the environmental impacts of population growth, examining the relationship between overconsumption in rich countries and underconsumption in poor countries. It discusses the projected growth rates and their implications for sustainability.

    Students will analyze the pressures placed on global resources and the need for economic adjustments to stabilize population and environmental health.

  • This module discusses fertility attitudes and practices, highlighting how many women prefer to have fewer children than they currently do. It explores the knowledge of contraception among women and the limited impact of family planning programs without improvements in living standards.

    Understanding these dynamics is crucial for developing effective population policies and addressing reproductive health issues.

  • This module examines the demographic transition in developing countries, highlighting the rapid changes in birth and death rates and the significant population growth that occurred in the 20th century. The 'population explosion' phenomenon is discussed in detail.

    Students will analyze the challenges posed by this rapid growth, including traditional issues of starvation, disease, and war, and their effects on population stabilization.

  • Female Disadvantage
    Robert Wyman

    This module addresses the female disadvantage in certain regions, particularly concerning the surplus of males resulting from sex-selective practices. It discusses the socioeconomic implications of these gender imbalances and how they affect reproductive health and family planning.

    Bangladesh serves as a case study, showcasing how effective family planning programs can significantly reduce fertility despite socioeconomic challenges.

  • This module explores population dynamics in traditional China, discussing historical factors that influenced population growth, including resource limitations and cultural practices. It highlights the prevalence of female infanticide and the fertility rates within marriage compared to Europe.

    Students will understand how these dynamics shaped family structures and social organization in traditional Chinese society.

  • This module focuses on modern China's population issues, analyzing the shifts in government policies regarding family size and fertility control. It discusses the One-Child Policy's implementation and its outcomes on population growth.

    Students will learn about the socio-economic implications of these policies and the challenges faced by contemporary Chinese society due to population momentum.

  • This module discusses the economic impacts of population growth, emphasizing the importance of fertility rates on economic development. It explores how rapid fertility drops can lead to economic booms as the workforce expands.

    Students will analyze the contrasting economic progress in regions with varying fertility rates, particularly focusing on Sub-Saharan Africa's challenges.

  • This module explores the economic motivations for fertility, discussing how poverty influences family size. It highlights the dual nature of children as both economic assets and liabilities.

    Students will explore the implications for public health and family planning, including the importance of effective sex education programs.

  • This module presents a global overview of abortion practices, examining the prevalence of abortion in various contexts. It discusses the rates of abortion compared to live births and the legal and social factors influencing access to abortion services.

    Students will analyze the implications of abortion legality on maternal health and societal perceptions of reproductive rights.

  • This guest lecture by William Ryerson explores the role of media in influencing fertility transitions in developing countries. It discusses the effectiveness of radio and television dramas in altering behaviors and attitudes regarding family planning and women's health.
