As an example, Canada's net population growth was 2.7 percent in the year 2022, dividing 72 by 2.7 gives an approximate doubling time of about 27 years. Thus if that growth rate were to remain constant, Canada's population would double from its 2023 figure of about 39 million to about 78 million by 2050. [2]

The Euler–Lotka equation, derived and discussed below, is often attributed to either of its origins: Euler, who derived a special form in 1760, or Lotka, who derived a more general continuous version. The equation in discrete time is given by. where is the discrete growth rate, ℓ (a) is the fraction of individuals surviving to age a and b ...
For example, say one wants to calculate with a calculator N 10, the population at the tenth generation, knowing N 0 the initial population and λ the finite rate of increase. With the last formula, the result is immediate by plugging t = 10 , whether with the previous one it is necessary to know N 9 , N 8 , ..., N 2 until N 1 .
