Americans speak a ton of languages, and this map shows which languages other than English and Spanish are the most common in each state and Washington, D.C.

The US Census Bureau's American Community Survey annually asks more than 1 million Americans questions about their lives, families, and backgrounds. One question asks respondents what language they mainly speak in their homes.

Using individual-level responses from the 2017 American Community Survey assembled and published by the Minnesota Population Center's Integrated Public Use Microdata Series program, we found the most common language spoken at home in each state, excluding English and Spanish.

English is, unsurprisingly, the most commonly spoken language across the US, and Spanish is second most common in 46 states and the District of Columbia. So we excluded those two languages in the above map.

The map shows a wide variety of languages. German is the most commonly spoken non-English, non-Spanish language in nine states, with French most common in six states and D.C. Vietnamese was the most common language in six states. Pennsylvania stands out for the prevalence of an archaic offshoot of West Central German known as Pennsylvania Dutch, spoken predominantly by Amish and Mennonite communities.

Most of us know about New Amsterdam and New England, but New France (or Nouvelle-France) lasted from the early 17th century until around 1803.

That year, President Thomas Jefferson bought up the last of France's western territory bordering the US from Napoleon Bonaparte, doubling the country overnight in what became known as the Louisiana Purchase.

Before that, however, Louisiana and its biggest city, New Orleans, had a French government, followed French customs, and spoke French. The language evolved over the 17th and 18th centuries from its original form, creating Louisiana French, or Louisiana Creole, a combination of French, English, Spanish, Native American, and African words. To this day, it's still spoken by around 175,000 people in Louisiana and Texas.

Although there were plenty of German immigrants present for the American Revolution, the US never considered adopting German as its official language, contrary to the persistent myth.
