- 3.1: The Human Population
- The human population is growing rapidly. For most of human history, there were fewer than 1 billion people on the planet. We’ve added 6 billion people to the human population in just a little over 200 years.
- 3.2: Demography
- Demography applies the principles of population ecology (chapter 2) to the human population.
- 3.3: Age structure diagrams
- This diagram shows the distribution by ages of females and males within a certain population in graphic form.
- 3.4: The Demographic Transition Model
- The demographic transition model shows the changes in the patterns of birth rates and death rates that typically occur as a country moves through the process of industrialization or development.
- 3.5: Life Expectancy
- Life expectancy is the average number of years that a person in a particular population is expected to live.
- 3.6: Fertility
- Fertility is the actual level of reproduction of a population per individual, based on the number of live births that occur.
