What are the qualities of population?
The population has the following characteristics:
- Population Size and Density:
- Population dispersion or spatial distribution:
- Age structure:
- Natality (birth rate):
- Mortality (death rate):
- Vital index and survivorship curves:
- Biotic Potential:
- Life tables:
Which are three main factors that caused population change?
The three main causes of population change
- Births – usually measured using the birth rate (number of live births per 1,000 of the population per year).
- Deaths – usually measured using the death rate (number of deaths per 1,000 of the population per year).
- Migration – the movement of people in and out of an area.

Why is the IPAT equation important?
A classic attempt to explain the relationship between a human population and its impact on the environment is the IPAT equation. The equation maintains that impacts on ecosystems (I) are the product of the population size (P), affluence (A), and technology (T) of the human population in question.
