A piece published in June 2010 by the National Center for Children in Poverty demonstrates the diversity of languages spoken at homes throughout the United States and how this has changed over time. Between 1980 and 2007 the number of people who spoke a language other than English at home increased at least twofold. By 2007, one out of every five Americans at least 5 years old spoke a different language at home. And during this same time period the American population increased by 34%, while the proportion of people who spoke only English at home grew by a smaller amount at 21%.
