Okay, so if it only includes "land" borders, why is Canada listed as an international border for Michigan and New York? Or, why is North Dakota listed as a border for Minnesota, for example?

I'm guessing it's because the statistic is defined as "Land" Borders. Why they chose that limitation is curious, but given that heading, their listings would be correct.

Still not fixed?

I am curious why Ohio and Pennsylvania don't have Canada listed as an international border? According to the Library of Congress (see link below), Ohio shares a 146 mile border with Canada, and Pennsylvania shares a 42 mile border with Canada.

Also, Michigan also shares a border with Minnesota and Illinois - neither are listed. Illinois shares a border with Michigan - it isn't listed. Minnesota share a border with Michigan - it isn't listed.
