Formerly the largest US immigrant group, European-born immigrants have seen their numbers decline in the United States over the past 50 years (notwithstanding a period of growth after the collapse of the Soviet Union). Though the number of these immigrants fell by only several million in numerical terms, the share of all European immigrants in the United States plummeted from nearly 75 percent in 1960 to 12 percent in 2010. At the same time, Eastern European immigrants have represented a larger share of that smaller pie during the past two decades.
