Population Growth & Trends - Chapter Summary
This chapter's lessons explore global population issues and the concerns and politics that accompany them. Our instructors help you understand how populations have moved from the countryside to cities and discuss models of this shift.
You will be introduced to theories regarding population growth and examine birthrate trends that are changing population demographics. Other lessons look at population shifts caused by death and migration. These lessons should leave you able to:
- Debate common concerns regarding global population issues
- Report on the history of migration from rural to urban areas in the U.S. and Europe
- Analyze theories and trends in the growth of cities
- Explain demographic transition and Malthusian theories as they relate to population growth
- Explore demographic changes resulting from altered fertility and birth rates
- Show how aging, death and migration influence population change
Our instructors guide you through these brief, engaging lessons, simplifying concepts by using examples to make their points. You can assess your knowledge with the quizzes that accompany each lesson. The jump feature in the timelines makes it easy to go back to areas in the lesson that need additional study. Each lesson also includes a written transcript, with key terms and phrases highlighted.
1. Global Population Issues, Concerns & Politics
The following lesson will cover the issue of global population trends and the resulting concerns. We'll explore concepts like carrying capacity, how developed and developing countries differ, and how some cultures and governments affect this issue.
2. Migration from Rural to Urban Settings in Europe and the U.S.: History and Effects
In this lesson, we will discuss some of the causes for people to migrate from a rural setting to an urban setting in Europe and in America. We will also learn the difference between immigration and emigration.
3. Historical Growth of Cities: Gemeinschaft, Gesellschaft, Gentrification & the Concentric Zone Model
In this lesson, we will discuss the contributions to classifying social change of two social scientists: Ferdinand Tonnies and Ernest W. Burgess. We will study concepts that include gemeinschaft, gesellschaft and gentrification.
4. Population Growth: Demographic Transition and Malthusian Theories
Population growth is not as simple as watching the total number of humans rise each year. This lesson explores how the experts actually calculate population growth rates, and how different theories explain why various regions of the world experience population growth changes in such different ways.
5. Demographic Changes from Fertility and Birthrates
Demographers focus on specific indicators of change in human populations. Two of the most important indicators are birth and death rates, or fertility and mortality. In this lesson, we will discuss the definitions of demography, fertility and mortality and their impact on a population.
6. Population Change from Aging, Death, and Migration
Fertility, mortality and migration are principal determinants of how a population can change, and they are at the very core of demographic studies. In this lesson, we will discuss how a population can change from fertility (birth), mortality (death), and migration.
