2.3 Pop Eco Flashcards
What happens to birth rate and death rate in Stage 1 of the demographic transition?
Both birth rates and death rates are high, leading to slow or no population growth.
What happens to birth rate and death rate in Stage 2 of the demographic transition?
Death rates decrease due to better healthcare and sanitation, while birth rates remain high, leading to rapid population growth.
What happens to birth rate and death rate in Stage 3 of the demographic transition?
Birth rates begin to decline due to economic changes and access to contraception, while death rates remain low, slowing population growth.
What happens to the birth rate and death rate in Stage 4 of the demographic transition?
Both birth rates and death rates are low, leading to stable or slowly growing populations.
What is the population growth rate like in Stage 5 of the demographic transition?
In some countries, birth rates fall below death rates, leading to negative population growth.
How does the population growth rate in developed nations compare to that in developing nations?
Developed nations typically have lower population growth rates, while developing nations have higher growth rates due to higher birth rates.
In the human population growth lab, what statistics are typically higher in developing nations compared to developed nations?
Developing nations tend to have higher birth rates, infant mortality rates, and population growth rates compared to developed nations.
In the human population growth lab, what statistics are typically higher in developed nations compared to developing nations?
Developed nations generally have higher life expectancy and lower infant mortality rates compared to developing nations.
How can an age structure diagram indicate future population growth?
If the diagram has a wide base (lots of young people), the population is likely to grow as these individuals reach reproductive age. A narrow base indicates slower or declining growth.
What does a rectangular-shaped age structure diagram typically indicate about a population?
It suggests a stable population where birth and death rates are balanced, and the population size is not changing rapidly.
How does the dependency ratio in developed nations differ from that in developing nations?
Developed nations often have a higher proportion of elderly dependents, while developing nations have a higher proportion of young dependents
How can a nation’s age structure impact its future economic growth?
Nations with a young, growing population may experience economic growth as more people enter the workforce, while aging populations may face economic challenges due to a shrinking labor force
Compare the population growth trends in developed and developing nations.
Developing nations generally experience rapid population growth due to higher birth rates and lower access to contraception, while developed nations have lower birth rates, leading to slower or even negative population growth.
Contrast resource use between developed and developing nations.
Developed nations use more resources per capita due to industrialized economies and higher standards of living, while developing nations use fewer resources but may face rapid environmental degradation due to population growth.
What are the long-term effects of low birth rates and aging populations in developed nations?
Low birth rates can lead to shrinking populations, which may cause economic challenges like labor shortages, higher healthcare costs, and increased pressure on pension systems.
