A new report shows explosive growth in the number of U.S. residents 5 years of age and older who speak a language other than English at home. The report by the Center for Immigration Studies, which breaks down new Census data, shows a record number of new immigrants in the country whose primary language is not English, and the fastest growing language is Arabic.

In 2015 a record 64.7 million U.S. residents spoke a foreign language at home – up 5.2 million since 2010 and up 1.5 million in just the last year. The largest percentage increase from 2010 to 2015 was for speakers of Arabic, Hindi (an India language) and Urdu (Pakistan’s national language). More than one in five U.S. residents now speaks a foreign language at home, according to the CIS report. FULL REPORT
