Module 4 Assignment 1: Discussion—Population Growth Look up the population of the state in which you live. If possible, find the annual percentage growth rate of your home city (use 0.9% if you can not locate this value). State of Tennessee population as of 2010: 6,346,105 with projected annual growth of 4.0%. (U.S. Department of Commerce, n.d.) Determine the population of your state 10 years from now. Formula: P (1 + r ) n P (1 + r ) n = 6,346,105 (1 + 0.04) 10 = 6,346,105 (1.04) 10 = 6,346,105 (1.480) = 9,392,235 Since the census is based on 2010, by 2020 the population is predicted to be 9,392,235. Determine how long and in what year the population in your state may double assuming a steady annual growth rate. Formula: DP = P (1 + r ) n DP = P (1 + r ) n = 12,692,210 = 6,346,105 (1 + 0.04) n 2 = (1.04) n log 2 = log (1.04) n log 2 = n log (1.04) n = log 2/log (1.04) = 17.7 Therefore, in 17.7 years the population will double assuming the annual growth rate of 4%. If we round 17.7 to a whole number of 18 the population will double in the year 2028 and this is adding the 18 years on from the census 2010 population. Look up the population of the city in which you live. If possible, find the annual percentage growth rate of your home city.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
