S = Population at the end of the year 2013 = 18522

i = Annual growth rate = 5%

n = Duration = 2 years (2011-12 ; 2012-13)

R= population at the beginning


S = R(1+i)^n

18522 = R( 1 + 5/100)^2

18522 = R( 1 + 0.05)^2

18522 = R(1.05)^2

18522 = R(1.1025)

18522/1.1025 = R

16800 = R = Population at the beginning of 2011
