New data collected by the Census Bureau shows that 3.1 million new immigrants (legal and illegal) settled in the country in 2014 and 2015, or more than 1.5 million annually.
In 2012 and 2013, 2.3 million immigrants arrived, about 1.1 million annually. In 2010 and 2011, 2.1 million new immigrants arrived, about one million annually.
All of the above numbers are based on publicly available information in Census Bureau data; no adjustments have been made for those missed by the bureau. But even without adjusting for undercount, the scale of new immigration is enormous.
The big increase in new arrivals in the last two years was driven by a rise in immigration from Latin America, particularly countries other than Mexico; South Asia (e.g. Pakistan and India); and East Asia (e.g. China and Vietnam).
