Addresses the Problem of Aging Population by Immigration in the United States

Abstract: The aging problem is becoming increasingly serious in various countries. The United States was also not spared and foreshadowed an equally negative future trend, which would lead to many problems in various aspects. Therefore, the United States has taken some policies to adapt to aging, but has not actually solved the problem. Some people believe that immigration can improve the problems brought about by the aging population. This article explores the mentioned approach through literature research and simulation. The way of immigration can improve population structure to alleviate population aging, which can be classified into two types - the age structure and the employment structure. In terms of age structure, the article will discuss how immigrants can alleviate the social risks caused by aging by the increasing number of immigrants at the working age. For the employment structure, the article will illustrate the answer to solve the slow economic evolution leaded by aging in regards to filling job vacancies for young and middle-aged immigrants.
