Environmental Science -Week 4 Assignment – Population Growth and Decline

 

In this assignment, you will analyze demographic data for various first, second, and third world countries.

Background

Review Chapter 4, “Human Populations” from Principles of Environmental Science: Inquiry & Applications and watch this five-minute video: Population Pyramids: Power Predictors of the Future – Kim Preshoff.

This week lecture is about 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 their effect on economies and societies.

At the most basic level, the increase or decrease in the 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.
