Oakland, Calif.

If you're an American, chances are you only speak one language. A 2001 Gallup poll reported that only one in four Americans can speak a language other than English. In a 2010 estimate, United States Secretary of Education Arne Duncan pegged the number even lower, at just 18 percent. Compare America to Europe, where 54 percent of citizens know at least two languages, and 25 percent know at least three.

That said, America still boasts a variety of multi-language regions -- you just have to know where to look. Our data geeks at FindTheHome compiled 2014 figures (latest available) from the American Community Survey to determine the most linguistically diverse city in every state.

How did we determine what was "most diverse?" We started with five language categories, as defined by the ACS: English, Spanish, Asian or Pacific Islander languages, Indo-European languages and other languages (including Navajo, Hungarian, Arabic, Hebrew and others). Specifically, the ACS tracks "language spoken at home," which we'll use for this particular analysis. Using this data, we set out to determine which cities in each state had the most even representation of each.

To determine even representation, we turned to the Herfindahl-Hirschman Index, a classic economic metric used to determine market diversity between companies. The same approach works for any other diversity calculation, including languages. We calculated this index* for every city in America, where scores approaching a low end of 2,000 represent lots of diversity, while scores approaching a high end of 10,000 represent no diversity at all (i.e. only one language). For this piece, we'll refer to the HHI as the "Linguistic Diversity Index."

The following cities emerged as the linguistic capitals. Note that many of the early cities on this list -- despite being the most diverse in their respective states -- still have little diversity. This is because the overwhelming majority of people in these states (ex: Vermont) speak English. By the latter half of the list, however, we'll see far more diverse cities emerge. For each city, we'll provide an interactive visualization to compare the city, county, state and national linguistic diversity.

*For the math geeks out there: we calculated the sum of the squares of each of the five percentages. The lower the resulting score, the more diverse the city.

*Once again, the Linguistic Diversity Index ranges from a score of 2,000 (lots of diversity) to 10,000 (no diversity).
