- What does a population pyramid graphically display?
- The age and sex structure of a population at a particular time.
- Define the Demographic Transition Model.
- A theoretical model describing how population changes as countries develop economically, moving through stages of varying birth and death rates.
- Describe Stage 1 of the Demographic Transition Model.
- High birth rates and high death rates with low population growth; characteristic of pre-industrial societies.
- Describe Stage 2 of the Demographic Transition Model.
- High birth rates but declining death rates due to improved healthcare and sanitation; rapid population growth.
- Describe Stage 3 of the Demographic Transition Model.
- Declining birth rates and low death rates; slowing population growth; characteristic of newly industrialized countries.
- Describe Stage 4 of the Demographic Transition Model.
- Low birth rates and low death rates with stable or slightly declining population; characteristic of developed, industrialized countries.
- Describe Stage 5 of the Demographic Transition Model.
- Declining population due to very low birth rates and potentially rising death rates; found in some developed countries with aging populations.
- What is the natural increase rate?
- The annual rate at which a population grows from births minus deaths, expressed as a percentage, excluding migration.
- Define exponential population growth.
- Rapid population growth where numbers increase at an accelerating rate, typically shown as a J-shaped curve on a graph.
- Define logistic population growth.
- Population growth that starts exponentially but slows as it approaches the environment's carrying capacity, shown as an S-shaped curve.
- What is carrying capacity?
- The maximum population size that an environment can sustain indefinitely given available resources.
- Define population density.
- The number of people per unit area, usually expressed as people per square kilometer or square mile.
- What is the crude birth rate?
- The annual number of births per 1,000 people in a population.
- What is the crude death rate?
- The annual number of deaths per 1,000 people in a population.
- Define total fertility rate.
- The average number of children a woman is expected to have during her reproductive lifetime.
