Does the United States have a national language?

French, the fourth largest foreign language, is spoken mainly by the small native French, Haitian or French-Canadian populations. It is widely spoken in Maine and in Louisiana, a former colony of France, where it is still used with English as the state's de facto official language. Germans, if European Americans were to be divided by national origin, would make up the largest single ethnic group in the United States. Italian, Polish, and Greek are still widely spoken among populations descending from immigrants from those countries in the early 20th century, but the use of these languages is dwindling as older generations die out. Starting in the 1970s and continuing until the mid 1990s, many people from the Soviet Union and later its constituent republics such as Russia, Ukraine, Belarus, and Uzbekistan have immigrated to the United States, causing Russian to become one of the minority languages in the United States.
