WebEquation 5-2 Estimating the population size between two census periods. Equation 5-3 Crude Birth Rate. For example, in order to calculate the crude birth rate for Durham County, North Carolina for the year 1999, it is necessary to estimate the midyear population for 1999. Equation 5-3 provides the calculation for the crude birth rate. WebStep 6: To calculate the growth rate, the equation of F = P(1+i)n is used. Solving for i, the equation becomes i = (F/P)1/n – 1, and the calculated growth rate is rounded to 1.39. i = (F/P)1/n – 1 F = target year AADT P = current year AADT, i = growth rate n = number of years between target and current years
