Study Notes
Population Density
- Calculated by dividing total population by total area.
Birth Rate as a Percentage
- Represents the proportion of births relative to total population.
- Formula: (total births ÷ total population) × 100.
Birth Rate per 1,000
- Indicates the number of births per 1,000 individuals in the population.
- Formula: (total births ÷ total population) × 1,000.
Death Rate as a Percentage
- Represents the proportion of deaths relative to total population.
- Formula: (total deaths ÷ total population) × 100.
Death Rate per 1,000
- Indicates the number of deaths per 1,000 individuals in the population.
- Formula: (total deaths ÷ total population) × 1,000.
Crude Birth Rate
- Measures the number of births in a population.
- Formula: (total # births ÷ total population) × 1,000.
Crude Death Rate
- Measures the number of deaths in a population.
- Formula: (total # deaths ÷ total population) × 1,000.
Population Growth Rate
- Represents the overall change in population size due to births, deaths, and migration.
- Formula: ((births + immigration) - (deaths + emigration) ÷ total population) × 100.
Population Change
- Measures the variation in population over time.
- Formula: (births + immigration) - (deaths + emigration) ÷ total population.
Doubling Time
- Estimates the time required for a population to double in size.
- Formula: 70 ÷ % growth rate = years to double.
Rate of Change
- Measures the change over time relative to the old value.
- Formula: (new - old) ÷ old.
Percent Change
- Expresses the change as a percentage of the old value.
- Formula: ((new - old) ÷ old) × 100.
Natural Rate of Population Increase
- The difference between total births and total deaths in a population.
- Indicates the growth potential without migration factors.
