Modeling Population Growth: Exponential and Hyperbolic Modeling

Abstract: A standard part of the calculus curriculum is learning exponential growth models. This paper, designed to serve as a teaching aid, extends the standard modeling by showing that simple exponential models, relying on two points to fit parameters do not do a good job in modeling population data of the distant past. Moreover, they provide a constant doubling time. Therefore, the student is introduced to hyperbolic modeling, and it is demonstrated that with only two population data points, an amazing amount of info… Show more

“…This differential equation produces a model of the following form p(t) = Ae kt . The equation p(t) = Ae kt represents the general solution of the differential equation [10]. When modeling a population with an exponential growth model, if the relative growth rate k is unknown, it should be determined.…”

“…If we consider a population to be the collection of individuals of a particular species that live within a welldefined area, any change in the number of individuals within this population comes about either by birth, or death, or immigration, or emigration [5]. Building a model to describe the dynamics of a particular population will involve having to choose the mathematical representation of the population in our model, and choosing a particular representation for the population [6]. Populations of organisms can even be studied by counting the number of adults at a reproduction time, to get a sequence of numbers, say P 1 , P 2 , .…”

“…In it the mechanistic model was presented as a growth model that correlates food availability, agricultural production, fertility rates and the size of a population. The concept of hyperbolic modeling was introduced by [6], and it was intended to moderate the excesses of exponential growth models. A transformation of the exponential and logistic models was proposed by [7].…”
