The Arizona-New Mexico Connection

No obvious explanation comes to mind for this remarkable correlation in Google Ngrams of “New Mexico” and “Arizona”. I checked a bunch of other neighboring states in various combinations, and nothing comes close. Anyone?


  1. Many people are geography-challenged,but might know there are few states between Texas and California, somewhere.

  2. Kansas and Missouri don’t get their act together until about 1915, but after that they have very similar values.

    Kentucky and Tennessee are pretty close, too, except for something strange going on in the 1920’s around the use of Kentucky.
