Arabic has become the fastest growing language in the U.S. and is spoken by more than 1million Americans at home, Census data reveal.

Arabic is the official language in more than two dozen Middle Eastern and North African countries, and is spoken all over thanks to its connection to Islam.

And with Muslims being the fastest growing block of new immigrants in the U.S., it's perhaps no surprise that Arabic script is becoming more common across the country.

Arabic is now the fastest-growing language in the U.S., according to a new report by the Center for Immigration Studies, based on Census data

Census data also reveals that 63.2million U.S. residents (more than one and five) speak a language other an English at home

Arabic isn't the only Islamic language sweeping the U.S. - Urdu, the national language of Pakistan, and Iranian Farsi, are also included in the list of top 10 fastest-growing languages.

The Census data also reveals that 63.2million U.S. residents (more than one and five) speak a language other an English at home, and that 41 per cent of residents have difficulty speaking English.

The Center for Immigration Studies is a Washington-based public policy think tank that claims it is 'pro-immigrant' but for 'low immigration'

In an interview with right-leaning outlet Breitbart, one of the report's author's said he believes that the rapid increase of Arabic speakers to the U.S. can pose a problem to national identity.

'Immigration is not just an economic issue. English as our common language is part of the glue that holds our country together. These numbers suggest that the levels of immigration are so high that it may strain that.

'After the last great wave of immigration more than a century ago, the level of immigration was reduced and remained low for half a century, which helped with assimilation. With no pause in immigration levels in sight, the nation is headed into uncharted territory,' Steve Camarota said.
