Abstract

Population growth is a dynamic process which depends upon many variables which result the population projection as a very complicated task. In this article, we try to project the population of Nepal for upcoming 100 years and also project the trend of population growth for next 300 years. In this projection, we use the Logistic Growth Model, a more realistic model of population projection. Here we use the every 10 years data of census and also calculate all the intermediate year’s data by using the exponential growth model. Thus, we use all together 41 years data in our calculation. By using the least square method to fit the Logistic Model in the past population and using the MATLAB, we calculate the logistic growth rate of population of Nepal is r = 3:6955%. The carrying capacity of Nepal is K = Pmax = 4; 38; 14; 550 and the inflection year at which the population is half of the maximum population ( K/2 = 2; 19; 07; 275) of Nepal as 1999 from when the population of Nepal will start to be more stable. The population growth rate will be remarkably reduced around the 2071 and the population of Nepal will start to remain more stable from around 2100. As the area of Nepal, its natural resources and possibilities of the dynamical connectivity between the rapid economically growing neighbors, the future population of Nepal seems to be manageable.
尼泊尔人口预测:Logistic方法
人口增长是一个动态过程,它取决于许多变量,这使得人口预测成为一项非常复杂的任务。在这篇文章中,我们试图预测尼泊尔未来100年的人口,并预测未来300年的人口增长趋势。在这个预测中,我们使用Logistic增长模型,这是一个更现实的人口预测模型。这里我们使用每10年一次的人口普查数据,并使用指数增长模型计算所有中间年份的数据。因此,我们在计算中使用了41年的数据。利用最小二乘法拟合过去人口的Logistic模型,并利用MATLAB计算得出尼泊尔人口的Logistic增长率为r = 3:6955%。尼泊尔的承载力K = Pmax = 4;38岁;14;550和人口为最大人口的一半的拐点年(K/2 = 2;19;07年;从1999年开始,尼泊尔的人口将开始趋于稳定。人口增长率将在2071年左右显著下降,尼泊尔的人口将从2100年左右开始保持稳定。作为尼泊尔的一部分,它的自然资源和经济快速增长的邻国之间动态联系的可能性,尼泊尔未来的人口似乎是可控的。
