It is possible that the Mexican immigration wave will resume as the U.S. economy recovers. Even if it doesn’t, it has already secured a place in the record books. The U.S. today has more immigrants from Mexico alone—12.0 million—than any other country in the world has from all countries of the world.1 Some 30% of all current U.S. immigrants were born in Mexico. The next largest sending country—China (including Hong Kong and Taiwan)—accounts for just 5% of the nation’s current stock of about 40 million immigrants.
