The formula for Compound Annual Growth rate (CAGR) is = [ (Ending value/Beginning value)^ (1/# of years)] - 1. In his example the ending value would be the population after 20 years and the beginning value is the initial population.

NettetLogistic population growth is the most common kind of population growth. In logistic population growth, the population's growth rate slows as it approaches carrying capacity. A population's carrying capacity is influenced by density-dependent and independent limiting factors. The equation for logistic population growth is written as (K-N/K)N. NettetThe maximal growth rate for a species is its biotic potential, or rmax, thus changing the equation to: d N d T = r max N. Figure 45.9 When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth.
