Chart of Melbourne's current and projected population growth. Melbourne is Australia's second-most populous city and has a diverse and multicultural population. Melbourne dominated Australia's population growth for the 15th year in a row as of 2017, adding 125,424 people between 2016 and 2017, and boomed past 5 million people in 2019.

The rate at which a population increases in size if there are no density-dependent forces regulating the population is known as the intrinsic rate of increase. It is d N d t = r N {\displaystyle {\mathrm {d} N \over \mathrm {d} t}=rN} where the derivative d N / d t {\displaystyle dN/dt} is the rate of increase of the population, N is the ...
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 discovery of gold in Victoria in mid-1851 sparked a gold rush, and Melbourne, the colony's major port, experienced rapid growth. Within months, the city's population had nearly doubled from 25,000 to 40,000 inhabitants. [52] Exponential growth ensued, and by 1865 Melbourne had overtaken Sydney as Australia's most populous city. [53]
The function also adheres to the sigmoid function, which is the most widely accepted convention of generally detailing a population's growth. Moreover, the function makes use of initial growth rate, which is commonly seen in populations of bacterial and cancer cells, which undergo the log phase and grow rapidly in numbers. Despite its ...
P 0 = P(0) is the initial population size, r = the population growth rate, which Ronald Fisher called the Malthusian parameter of population growth in The Genetical Theory of Natural Selection, [2] and Alfred J. Lotka called the intrinsic rate of increase, [3] [4] t = time. The model can also be written in the form of a differential equation:
