Demographic Changes from Fertility and Birthrates

1. 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.

Population Change from Aging, Death, and Migration

2. 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.

Global Trends in an Aging Population

3. Global Trends in an Aging Population

In this lesson we look at global trends that are occurring with the elderly, as well as specific issues that affect industrialized and developing nations. Lastly, we look at how culture is affected by all of this.

Demographic Balancing Equation, Natural Increase & Net Migration

4. Demographic Balancing Equation, Natural Increase & Net Migration

How do we figure out the population on a year-to-year basis? Explore the ideas behind the demographic balancing equation, natural increase, and net migration in this lesson. Then test your understanding with a brief quiz.

What Is Demographic Transition? - Definition & Stages

5. 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.

The Theory of Demographic Transition: Overview

6. The Theory of Demographic Transition: Overview

Populations change over time. The growth or decline of a population can have an effect on the quality of life for people within that population. In this lesson, you'll learn about the theory of demographic transition, which is a model used to study and predict population changes.

Malthusian Theory of Population Growth: Definition & Overview

7. Malthusian Theory of Population Growth: Definition & Overview

Known for his work on population growth, Thomas Robert Malthus argued that if left unchecked, a population will outgrow its resources, leading to a host of problems. In this lesson, we will define and discuss the Malthusian theory of population growth.

The Population Pyramid

8. The Population Pyramid

In this lesson, we look at what a population pyramid is, how to read it, some interesting features about them, and what are some prototypical examples of them.
