Study Notes
Definition of Population
- A population is a group of individuals of the same species living in a specific geographic area.
- It can refer to humans, animals, or plants.
Population Characteristics
- Size: The number of individuals in a population.
- Density: The number of individuals per unit area.
- Distribution: The way individuals are spread out across a geographic area.
- Composition: The characteristics of the population, such as age, sex, and occupation.
Population Dynamics
- Birth rate: The number of births per 1,000 individuals in a population per year.
- Death rate: The number of deaths per 1,000 individuals in a population per year.
- Migration: The movement of individuals into or out of a population.
- Growth rate: The rate at which a population increases or decreases in size.
Population Growth Models
- Exponential growth: A model that assumes a constant rate of growth.
- Logistic growth: A model that assumes a slowing of growth as the population approaches its carrying capacity.
Population Pyramids
- A graphical representation of the age and sex distribution of a population.
- Broad base: A large number of individuals in the younger age groups.
- Narrow top: A small number of individuals in the older age groups.
Population Parameters
- Fecundity: The average number of children a woman would have in her lifetime.
- Mortality rate: The probability of death at a given age.
- Life expectancy: The average number of years an individual is expected to live.
Population Theories
- Malthusian theory: The idea that population growth is limited by resource availability.
- Demographic transition theory: The idea that population growth slows as a country develops economically.
