Study Notes
Definition and Measurement
- Population refers to the total number of individuals inhabiting a specific geographic area, such as a city, country, or region.
- Population can be measured in terms of size, density, and distribution.
Types of Population
- Crude population: The total number of people living in a given area, without regard to age, sex, or other characteristics.
- Resident population: The number of people who usually live in a given area, excluding temporary visitors or migrants.
- De facto population: The number of people present in a given area at a specific time, including temporary visitors or migrants.
Population Dynamics
- Population growth rate: The rate at which a population increases or decreases over time, expressed as a percentage.
- Birth rate: The number of live births per 1,000 people in a population per year.
- Death rate: The number of deaths per 1,000 people in a population per year.
- Migration: The movement of people into or out of a population, affecting its size and composition.
Population Structure
- Age structure: The distribution of a population by age, often represented as a pyramid or graph.
- Sex structure: The distribution of a population by sex, with males and females represented as percentages.
- Dependency ratio: The ratio of dependents (children and elderly) to working-age individuals in a population.
Population Pyramids
- Stationary population pyramid: A population with a stable age structure, where the number of births and deaths are equal.
- Expanding population pyramid: A population with a high birth rate and a growing population.
- Contracting population pyramid: A population with a low birth rate and a declining population.
Population Issues
- Overpopulation: A situation where the population size exceeds the available resources, leading to environmental degradation and social problems.
- Underpopulation: A situation where the population size is too low to support economic growth and social welfare.
- Aging population: A population with a high proportion of elderly individuals, leading to concerns about healthcare, social security, and workforce sustainability.
