Introduction
In this paper, we are going to discuss the logistic model of predicting the population and its historical applications on the size of US population. Population of the United States is the total number of people living in the United States with US citizenship. Population projection is the estimation of the future size of the population. Section II will mention the official source and relating background about the size of US population. Section III will address why population projection is important. Section IV will briefly go over exponential population model which had great influence on the invention of logistic population model. Section V will focus on logistic model and its derivations. Section VI will discuss some historical application of logistic model. Section VII includes citations.
