Methods of population forecasting
WebA constant value of percentage growth rate per decade r is analogous to the rate of interest per annum. (Methods of Population forecasts in civil engineering) Pn= [P0 {1+ (r/100)}^n] Where P0 = initial population. Pn = future population. r= growth rate percentage. Where growth rate calculated. r = (increase in population/original population)* 100.
