The respective fits predict 2050 populations of 233,000 and 273,000, respectively. We also chose to model population growth using the growth rate of .12% per month (www.oregonfuture.oregonstate.edu), that found since the 2000 census. Using this model, the 2050 population is predicted to be: Pert = 157,000e(.0012*46*12) = 300,000
