Population Growth
This type of population growth produces a J-shaped curve.
What is exponential growth?
The average number of children born to each woman in a population decreases with higher levels of this.
What is quality of life?
This stage of the demographic transition is characterized by high birth and death rates.
What is the preindustrial stage (Stage 1)?
The movement of individuals out of a population.
What is emigration?
This is the period in human history when farming began and populations increased.
What is the agricultural revolution?
This term describes the maximum number of individuals an environment can support sustainably.
What is carrying capacity?
The global trend where industrial development increases carbon emissions is tied to this human activity.
What is industry?
During this stage, death rates fall but birth rates remain high.
What is the transitional stage (Stage 2)?
The pattern of survival rates over an organism’s lifetime, often shown as a curve.
What is survivorship?
The process where societies shift from high birth and death rates to low rates.
What is demographic transition?
Population growth slows or stops after a period of exponential growth, producing an S-shaped curve.
What is logistic growth?
Overhunting by this type of society has contributed to the extinction of many species.
What are hunter-gatherers?
This stage is marked by declining birth rates and stabilizing population growth.
What is the postindustrial stage (Stage 4)?
Countries with high levels of income and industrialization are called this.
What are developed countries?
The overall term describing all changes humans make to the environment.
What is human impact?
The movement of individuals into a population.
What is immigration?
The transition from this economy to industry dramatically increased human environmental impact.
What is agriculture?
The demographic transition model explains the shift in population dynamics based on this overarching factor.
What is development?
These countries often have higher population growth rates and lower income levels.
What are developing countries?
This describes the phenomenon when population growth increases with better living conditions.
What is quality of life?
The concept that shows the number of births and deaths needed to maintain population stability.
What is replacement level?
This term explains the relationship between a country’s wealth and its environmental impact.
What is gross national product (GNP)?
This graph type shows the distribution of ages within a population and can indicate growth trends.
What is an age structure diagram/population pyramid?
The loss of an entire species from the planet.
What is extinction?
Overpopulation leads to the depletion of these resources, critical for sustaining life.
What are natural resources?
