1. ChOoZe a country to research the population growth of.o

Example:US

2.UZinG thewebsite on world population, tell what the current population growth rate is.Is it increasing or decreasing?Example:0.6%increasing

3.UZe the formulaA=Pert and also the formula for growth or decay to find two estimates for the population of this country in 2050 if the current rate of growth continues. (Hint: If your population is decreasing, you will need to use a negative sign on your rate for this equation.)

Example:

NOTE:THIS EXAMPLE IS FROM 2019,so t=31.Please adjust for the current year.

A=Pert

=(329,015,732)e(.006)(31)=396,273,871 people in 2050

329,015,732 is US population in 2019=P

0.6%=0.006=r

(2050-2019)=31=t

AND

A=P(1+r)t=329,015,732(1+0.006)31

=396,053,693 people in 2050

Note:If population is decreasing you will use the formula for exponential decay.

4.Find when the population of this country will double if the rate stays the same using the equation for doubling time.

Example:t=ln2r

=ln20.006

=115 years

5.CliK on the name of the country on thewebsite on world population(Links to an external site.)

.This will bring to more detailed information about the country.TeLl what the estimated population in 2050 will be according to the website.

Example:In 2050, the US population will be 379,419,102 according to the website chart.Later in the article it says the population in 2050 will be 438 million.

6.Tel how your answers from question #3 compare to what the website says the population will be.

Example:MiE answer is between the two valuesthatthe website gives.

7.UZe the historic data table to find historical data for the country.What was the population in 1960?TeLl what has happened with population since that time.UZe the information about the country to give some background about what has happened in the country to affect the population growth rate.

Example: 186,720,571(Hint:Use the graph given-find 1960 and hover over it.The population will appear.The population continues to grow at a slow rate due to immigration.Historically, the hurricane in Galveston, Texas in 1900 greatly affected the population and killed between 6000 and 12,000 people.
