Question 1

What did we learn in this unit?

Answer 1

Factors affecting population growth rate and demographic transition.

Question 2

What is one factor affecting population growth rate?

Answer 2

• Sex ratio - number of females vs. number of males.
• more females =higher growth

Question 3

What is another factor affecting population growth rate?

Answer 3

• Age structure - the number of females at reproductive age born in the same cohort
• more females at reproductive age increases population growth

Question 4

Would a longer or shorter generation time lead to larger population growth?

Answer 4

A shorter generation time would lead to a larger population growth because that would force reproduction to occur faster and earlier.

Question 5

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

Answer 5

By showing the distribution of different age groups, which indicates birth rates, and future changes in population size

Question 6

Do developing or developed countries have higher birth rates?

Answer 6

Developing have higher birth rates compared to developed countries.

Question 7

What are two concerns with population growth?

Answer 7

Increasing the extraction of resources and increase in freshwater used for drinking,agriculture, recreation, and industrial processes.

Stage 2 - Death rates drop due to improvements in health care and birth rates remain high; rapid growth

Question 12

Describe stages 3 and 4 of demographic transition

Answer 12

Stage 3 - Birth rates start to decline and death rates continue to fall; slowing growth
Stage 4 - Birth and death rates are both low so growth is minimum and stabilizes

Question 13

Describe stages 5 of demographic transition

Answer 13

Stage 5 - Birth rates fall below death rates which leads to declining population

Question 14

What part of the population do we want an increase in?

Answer 14

The younger population because represent the future workorce and drive economic growth and innovation so country stays better.
