摘要：The purpose of this paper is to use mathematical models to predict the population growth of Ghana. Ghana is a small country located in West Africa. It borders Burkina Faso, Ivory Cote and Togo and the Gulf of Guinea. The Exponential and the Logistic growth models were applied to model the population growth of Ghana using data from 1960 to 2011. The Exponential model predicted a growth rate of 3.15% per annum and also predicted the population to bel114.8207 in 2050. We determined the carrying capacity and the vital coefficients a and b are 0.0523and 7.7468 x 10-5, respectively. Thus the population growth of Ghana according to the logistic model is 5.23% and predicted Ghana’s population to be 341.2443 in 2050. The MAPE of was computed as 16.31% for the Exponential model and 95.21 for the Logistic model.
