Language distribution between states

I mentioned this in class already, but this map shows the most common language in each state besides English and Spanish.

Some of the answers are easy to guess - it's French in Louisiana and Mississippi, big surprise - but others are not so predictable. For example, for Texas, it's Vietnamese. You don't usually think of Texas as a place with a lot of Asian immigrants of any kind, but apparently it has the second-highest Vietnamese-American population in the country (source). German was listed the most, with sixteen states. Additionally, three states had Native American languages listed - Dakota for South Dakota, and Navajo for Arizona and New Mexico.

Another thing that surprised me was that the only state that has Chinese listed is New York, since historically the East Coast was more associated with European immigrants rather than Asian. Then again, that was a long time ago, and it's probable that the demographics have shifted since then.

For California, apparently it's Tagalog. I expected it would be something Asian, and I knew there are a lot of Pacific islanders in general in the state, but I didn't know we had that big of a Filipino community. There were two other states - Nevada and Hawaii - that were also listed with Tagalog.
