U.S. Immigrant Population Hit Record 43.7 Million in 2016
Overall growth slowed, but Middle Eastern, non-Mexico Latin American, Asian, and sub-Saharan African populations grew substantially

On September 14, 2017, the Census Bureau released some data from the 2016 American Community Survey (ACS) that shows uneven growth in the immigrant population in the last year. The number of immigrants (legal and illegal) from the Middle East, Latin American countries other than Mexico, Asia, and Sub-Saharan Africa grew significantly, while the number from some places, such as Mexico, Europe, and Canada, grew not at all or even declined. The Census Bureau refers to immigrants as the foreign-born, which includes all those who were not U.S. citizens at birth. The Department of Homeland Security has previously estimated that 1.9 million immigrants are missed by the ACS, so the total immigrant population in 2016 was likely 45.6 million.1
