BIOS 135 Population Dynamics
Intro
This week ilab was to understand, compare, and calculate the world’s population rate.
Interactive media, World Bank, CIA Factbook websites was use to gain the different elements which
brought each country to its population level. Financial income plays a major role in the understanding of
fertility rates, whether an increase leads to poverty or a decrease leads to a higher capital income.
Procedure
1. Use the World Bank's definitions for low income countries, lower middle income countries,
upper middle income countries, and high income countries. Select a country in each
category and complete the speadsheet for exercises 1- 3 located above. The World Bank
and CIA Factbook websites are in the course webliography and should be used to help
complete your table.
2. Starting with a hypothetical population of 14,000 people and an even age distribution
(1,000 in each age group from 1-5 to 66-70 years), assume that the population initially has
a total fertility rate of 2.0 and an average life span of 70 years. Using the spreadsheet for
exercises 1-3, estimate how the population will change from this generation to the next
under each of the following conditions.
3. a. Total fertility rate and life expectancy remain constant.
4. b. Total fertility rate changes to 4.0; life expectancy remains constant.
5. c. Total fertility rate changes to 1.0; life expectancy remains constant.
6. d. Total fertility rate remains at 2.0; life expectancy increases to 100.
7. e. Total fertility rate remains at 2.0; life expectancy decreases to 50.
F. Total fertility rate changes to 4.0; life expectancy increases to 100.
8. Most developed countries have infant mortality rates of around 5 deaths per thousand live
births, and some developing countries have infant mortality rates exceeding 100 deaths per
1,000 live births. How would either of these rates affect our final populations? Use the
speadsheet for exercises 1-3 found above to adjust your calculations.
9. Using current population growth rates (obtained from the World Bank or CIA Factbook)
and using the rule of 70, project how long it will take the population of the world and the
following countries or regions to double. What is happening to population growth rates
worldwide?
