Study Notes
Population and Density Concepts
- Age-sex distribution: Represents the composition of a population by age and sex, crucial for understanding demographic trends. Often illustrated through population pyramids.
- Agricultural density: Indicates the number of farmers per unit area of farmland, useful for assessing agricultural sustainability.
- Arithmetic density: Refers to the number of people per unit area of land, facilitating comparisons of population concentration across different regions.
- Carrying capacity: The maximum population size an environment can sustain without ecological degradation, essential for resource management.
Birth and Death Rates
- Crude Birth Rate (CBR): Calculated as the number of live births per 1,000 people annually, provides insight into population growth trends.
- Crude Death Rate (CDR): Represents the number of deaths per 1,000 people annually, used to assess public health conditions and mortality trends.
Demographic Models
- Demographic Transition Model (DTM): Illustrates the transition from high birth and death rates to low rates as a country develops economically, highlighting stages of demographic change.
- Dependency ratio: A measure comparing the population not in the labor force (children and elderly) to those in it, indicating economic pressure on productive individuals.
Population Growth Dynamics
- Doubling time: The period required for a population to double at a constant growth rate, applicable across various growth scenarios.
- Ecumene: Refers to inhabited land, denoting areas of permanent human settlement, vital for understanding human spatial distribution.
Health Patterns
- Epidemic: Characterized by a sudden and widespread outbreak of infectious diseases in a given community, significant in public health discourse.
- Epidemiologic Transition: A theory describing the shifts in population health patterns, connecting changes in fertility, life expectancy, and mortality causes over time.
