2013 was a year of massive global population migration. The number of immigrants worldwide increased from 154 million in 1990 to 232 million, the highest in history, accounting for 3.2% of the global population. Among them, the United States leads with 4.579 million immigrants, far ahead of other countries. Russia, ranked second, has only 1.119 million immigrants.
Currently, the main sources of immigration to the United States are Hispanic and Asian. In recent years, Asian immigrants have surpassed their Hispanic counterparts to become the largest immigrant group in the United States. These individuals primarily come from India, China, and South Korea. In 1990, there were only 61,000 American citizens born in China, ranking this immigrant group as the 11th in the United States. By 2010, China had become the 2nd largest source of immigrants to the United States, with 196,000 American citizens of Chinese origin.
From the perspective of immigration sources, developing countries have contributed the most immigrants worldwide. After 2000, India, Mexico, Russia, and China have consistently ranked as the top 4 countries that export immigrants. A significant wave of migration has formed from China; between 1990 and 2013, the number of migrants from China increased from 425,000 to 934,000, an increase of 119.6%, according to statistics from 2013. In addition to the United States, the countries that received the most Chinese immigrants were Canada, Japan, and Singapore.
