9.3 Study Guide

Question 1

What happens with birth rate, death rate, and population growth rate in each stage of the demographic transition?

Answer 1

This process tends to occur in three stages. First, birth and death rates are both high, so little growth occurs. Second, death rates fall due to improved living conditions, while birth rates remain high. During this period population grows rapidly.

Question 2

Statistics from the human population growth lab that correlate with developed vs. developing nations

Answer 2

The populations of developed countries are generally more stable and will show a decline in growth rate from accounting for 17% of the world population to 14% by 2050. Whereas, the developing countries’ growth rate will increase from accounting for 83% of the world population to 86% by 2050.

Question 3

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

Answer 3

An age structure diagram is a model that predicts the population growth rate by a shape. It shows a comparative ratio of males to females and the bars show various age groups from infants to adolescents to reproductive and post-reproductive stages.

Question 4

Comparing and contrasting population growth and resource use between developed and developing nations?

Answer 4

• Developing nations:
  higher fertility, infant mortality, and death rates
  Lower life expectancy
  Low per capita resource use
• Developed nations: more stable and sometimes declines
  Lower fertility, infant mortality, and death rates
  Higher life expectancy
  High per capita resource use
