Question 1

Stage 1 of Demographic Transition: What happens with birth rate, death rate, and population growth rate?

Answer 1

Birth Rate: High
Death Rate: High
Population Growth Rate: Low or stable
Explanation: In this stage, both birth and death rates are high due to limited medical knowledge and poor living conditions, leading to low population growth.

Question 2

Stage 2 of Demographic Transition:
What happens with birth rate, death rate, and population growth rate?

Answer 2

Birth Rate: High (but falling)
Death Rate: Rapidly declining
Population Growth Rate: Rapid increase
Explanation: Death rates drop due to improvements in healthcare and sanitation, while birth rates remain high, leading to a population boom.

Question 3

Stage 3 of Demographic Transition:
What happens with birth rate, death rate, and population growth rate?

Answer 3

Birth Rate: Declining
Death Rate: Low
Population Growth Rate: Slowing down
Explanation: Birth rates begin to decline due to social changes, such as increased access to education, leading to a slower population growth rate or stabilizing.

Question 4

Stage 4 of Demographic Transition:
What happens with birth rate, death rate, and population growth rate?

Answer 4

Birth Rate: Low
Death Rate: Low
Population Growth Rate: Stable or slight increase
Explanation: Both birth and death rates are low, leading to a stable or slowly growing population, typical of developed countries.

Question 5

What are the key differences between developing countries and developed countries?

Answer 5

Developed Nations: Lower birth and death rates, higher life expectancy, lower infant mortality, and slower population growth.

Developing Nations: Higher birth and death rates, lower life expectancy, higher infant mortality, and faster population growth.

Question 6

How can an age structure diagram be used to predict population growth?

Answer 6

Age structure diagrams show the distribution of a population by age and gender. A broad base indicates a high proportion of young people, suggesting potential for rapid population growth. A narrow base suggests an aging population with slower growth or decline.

Question 7

Compare and contrast population growth and resource use between developed and developing nations.

Answer 7

Developed Nations: Tend to have slower population growth but higher per capita resource use. This often leads to greater environmental impact per person.

Developing Nations: Often experience faster population growth but lower per capita resource use. However, the rapid population increase can strain local resources and infrastructure.
