About This Chapter
Population and Migration - Chapter Summary
In this chapter, our instructors explain all aspects of the human population, including factors that affect population size, biotic potential and carrying capacity of a population, and the history of human population growth and carrying capacity. Lessons also discuss Mathus' theory of human population growth.
You'll learn all about certain reoccurring themes in history including migration, evolution, aggression and industrialization. As you progress through the chapter, you'll find out about population density and population pyramids. You can study how fertility and changing birthrates have affected demographics in different countries. After completing this chapter, you should be able to:
- Discuss factors affecting the size of the human population
- Define biotic potential and carrying capacity
- Explain Malthus' Theory of Human Population Growth
- Discuss recurring themes in history that affect human population
- Discuss population density around the world
- Explain demographic transition
- Discuss population growth, population characteristics of various countries, and population distribution
- Explain how fertility and birthrates affect demographics
- Outline issues in human trafficking and slavery
You'll find short, engaging video lessons that draw you in and make learning the material fun. Along with the lessons are brief self-assessment quizzes and written transcripts. We highlight the major points you need to know by giving you key terms that are often linked to text lessons. If you want to go back to a specific portion of a video, you can do that with our convenient video tags. All these materials were written and compiled by our expert instructors.
1. The Human Population: Factors that Affect Population Size
The human population is constantly changing. In this lesson, we will explore the factors that cause increases and decreases in the human population, including births, deaths, immigration, and emigration.
2. Biotic Potential and Carrying Capacity of a Population
When you look around, you can see a number of different individuals and species. In this lesson, we will explore the factors that control and define how many organisms can really inhabit a particular ecosystem or habitat.
3. The History of Human Population Growth and Carrying Capacity
Most of us are used to the current size of the human population but it was not always this large. In this lesson, we will explore the history of human population growth and the future of its growth.
4. Thomas Malthus' Theory of Human Population Growth
In this lesson, we will explore the ideas of Thomas Malthus and his predictions for the growth of the human population. We will also investigate if his predictions have come true or not.
5. Recurring Themes in History: Societal Migration, Evolution, Aggression & Industrialization
In this lesson, we will examine some recurring themes throughout history. We will see how societal migration, cultural transformation, conflicts, industrialization, and other trends help facilitate historical development.
6. What Is Population Density? - Definition & Measurements
This lesson will seek to explain the concept of population density. It will focus on three specific measurements of density. They are arithmetic, physiological, and agricultural density.
7. Population Density Around the World
This lesson will explain the concept of population density. In doing this, it will discuss sparsely versus densely populated areas. It will also identify the primary and secondary population clusters of the world.
8. What Is Demographic Transition? - Definition & Stages
There are many differences between non-industrial and industrial countries. In this lesson, we will explore the concept of demographic transition and the stages that guide a country through its changes into an industrial country.
9. Population Pyramids: Definition, Types, Stages
Did you know that there are five stages of population pyramids? In this lesson, learn more about the different types, and stages, of population pyramids as well as look at some examples.
10. 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.
11. Population Characteristics of Highly Developed & Developing Countries
The population of a country is based on many factors. In this lesson, we will explore several important factors that differ between developed and developing countries.
12. Population Distribution: Rural vs. Urban Areas
The distribution of people varies depending in the type of location. In this lesson, we will explore how people are distributed between rural and urban areas and how these populations have changed over time.
13. 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.
14. Global Human Trafficking and Slavery Issues
The following lesson addresses the combination of forced labor and global migration, which has led to the modern issues of human trafficking and slavery. A short quiz will follow the lesson to check your understanding.
