U.S. immigrant population hits all-time high: 41.3 million people

The U.S. immigrant population has doubled since 1990, while the general population has risen just over 20 percent, and quadrupled since 1970, while the general population has risen just over 50 percent since then. The greatest increases over the last three years in the immigrant population over the last three years, between July 2010 and July 2013, came not from Latin America from the Middle East, Asia, and the Caribbean.

The number of immigrants from Mexico and Europe living in the U.S. has actually declined slightly since 2010, but Mexicans still make up the largest immigrant population in the United States, with 11.6 million legal and illegal immigrants residing here.
