One of the more interesting developments in U.S. immigration over the past few years is that Asians have overtaken Hispanics as the country's largest immigrant population.
Using percentage of foreign-born annual arrivals, the Pew Research Center reported that in the last three years Asia has became the top source of immigrants. 430,000 Asians came to the U.S. in 2010, a number that represents 36 percent of all new legal and illegal immigrants. In the same year there were 370,000 new Hispanics arrivals.
A recent article in Forbes detailed some of the reasons we have seen the shift. High growth rates in Asian countries, along with economic conditions in the U.S. and Mexico/Central America have combined to move the groups in opposite directions.
