What does the immigration deficit mean?

According to the Blue Book Report on International Migration in China (20 14) published by China Globalization Think Tank and Social Science Literature Publishing House, after the reform and opening up, a "new class" has emerged among overseas Chinese, that is, people who immigrated from Chinese mainland in various names and forms, such as studying abroad, exporting foreign labor services and emigrating relatives. This generation of immigrants is usually called "new immigrants". They are mainly intellectual elites and wealth elites, with the characteristics of large quantity and high level. According to the Blue Book, among the 50 million overseas Chinese, new immigrants account for about 1/5, which is about100000. According to the data of the sixth population census in China, there are 593,832 foreigners living in China (excluding Hong Kong, Macao and Taiwan), and there is a huge immigration deficit between them.

Dr. Wang, editor-in-chief of Blue Book and director of China and Globalization Think Tank, called the huge migration deficit "migration deficit". According to the estimation of the United Nations Department of Economic and Social Affairs, the number of immigrants in China has been very low, only about 376,900 in 190, and increased to about 848,500 in 20 13, which has formed an "immigration deficit" with the huge immigrant population.
