This template quickly calculates the population growth rate given two pairs of years and populations using the formula from Population growth:
Grand Rapids is a city in and county seat of Kent County, Michigan, United States. [4] At the 2020 census, the city had a population of 198,893, [5] making it the second-most populous city in Michigan, after Detroit.
The Grand Rapids–Wyoming Combined Statistical Area is the 2nd largest CSA in the U.S. state of Michigan (behind Metro Detroit). The CSA had a population of 1,486,055 at the 2020 census. The CSA had a population of 1,486,055 at the 2020 census.
The equation for exponential mass growth rate in plant growth analysis is often expressed as: = Where: M(t) is the final mass of the plant at time (t). M 0 is the initial mass of the plant. RGR is the relative growth rate. RGR can then be written as:
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:

The algebraic symbols b, d and r stand for the rates of birth, death, and the rate of change per individual in the general population, the intrinsic rate of increase. This formula can be read as the rate of change in the population (dN/dt) is equal to births minus deaths (B − D). [2] [13] [17]
The Leslie matrix is a discrete, age-structured model of population growth that is very popular in population ecology named after Patrick H. Leslie. [1] [2] The Leslie matrix (also called the Leslie model) is one of the most well-known ways to describe the growth of populations (and their projected age distribution), in which a population is closed to migration, growing in an unlimited ...
