Witryna3 kwi 2024 · If we return data and compute the per capita growth rate over a range of years, we generate the data shown in Figure \(\PageIndex{1}\), which shows how the per capita growth rate is a function of the population, \(P\). Figure \(\PageIndex{1}\): A plot of per capita growth rate vs. population P. WitrynaIn our case, we grew from 1 to 2, which means our continuous growth rate was ln (2/1) = .693 = 69.3%. The natural log works on the ratio between the new and old value: new old. In other words: 100% discrete growth (doubling every period) has the same effect as 69.3% continuous growth.
