This second lab draws heavily on Chapter 4, “Human Populations” in your text. To successfully complete this lab, you will want to study this chapter carefully. You may also find it useful to watch this five-minute video: Population Pyramids: Power Predictors of the Future.
At the most basic level, the increase or decrease in population can be calculated by following this simple formula:
BIRTH RATE – DEATH RATE + IMMIGRATION = GROWTH RATE
Birth and death rates are expressed in a number of different ways. Overall birth rates are often expressed as the number of births per woman over her life. Overall death rates are simply the number of deaths per year.
To predict population growth, however, population models use birth and death rates specific to each age group, over a step of five years.
In this lab, you will analyze demographic data for various first, second, and third world countries. As you learned in the text this week, population pyramids generated from this data illustrate the population distribution. Whether countries have a large, young population a large, old population, or a population that is relatively stable, they all have unique challenges to address. This lab will help you further explore the concept of population distributions and its effect on economies and societies.

Lab 2: Population Growth and Decline Instructions
Objective
Use United Nation’s population data (2015) and population pyramids to explore the challenges different population distributions have on economies and societies. Note: This is the latest data available. The United Nations updates this information about every 10 years.
Step Step Description
1 Review the demographic data provided here for the USA, Japan, China, and Nigeria. For each of these countries, you will see a population pyramid for 2015 and the population pyramid prediction for 2100.
2 Based on the data provided for these four countries, complete Columns 2–7 in Table 1: Demographic Data on the Population Growth and Decline Template. This will give you a view of the demographic transition continuum.
3 Rank the countries by growth rate in the year 2100 from highest (earliest in the demographic transition) to lowest (farthest along the transition). You will enter this information in Column 8, Rank in Transition of Table 1 on the Population Growth and Decline Template.
4 Describe the shape of the pyramid of population by age for each country. You will write your descriptions in the appropriate space in Table 2, Shape of Population Pyramid on the Population Growth and Decline Template.
