WASHINGTON (AP) — For the first time, the influx of Asians moving to the U.S. has surpassed that of Hispanics, reflecting a slowdown in illegal immigration while American employers increase their demand for high-skilled workers.

An expansive study by the Pew Research Center details what it describes as “the rise of Asian-Americans,” a highly diverse and fast-growing group making up roughly 5 percent of the U.S. population. Mostly foreign-born and naturalized citizens, their numbers have been boosted by increases in visas granted to specialized workers and to wealthy investors as the U.S. economy becomes driven less by manufacturing and more by technology.
