Create all sorts of fun maps thanks to the folks at the MLA: map language-speakers by county, by zip code, and all sorts of other good stuff. Pull-down menus and such let you re-draw the map according to your curiosity. (The above map, FYI, is of Hungarian speakers by county. I think. Of course, handily, I didn’t include the color-coded key, so if you’re really curious, you’ll have to dial up the map yourself.)
