WebFeb 11, 2024 · Check that the growth rate is small enough for this method. Doubling time is a concept used for quantities that grow exponentially. Interest rates and the growth of a population are the most common examples used. If the growth rate is less than about 0.15 per time interval, we can use this fast method for a good estimate. WebSep 5, 2024 · The Population Growth Rate ( r ) The population growth rate (sometimes called the rate of increase or per capita growth rate, r) equals the birth rate ( b) minus the death rate ( d) divided by the initial population size (N 0 ). Another method of calculating the population growth rate involves final and initial population size (figure 5.3. a ).
