Lansing in Southern Michigan I think not What is the source or justification for this apparently arbitrary decision I say apparently arbitrary because I can find no evidence that the regions of Michigan are official governmental designations The media Lansing State Journal and TV Stations WLNS WILX WSYM all refer to Lansing as being in Mid Michigan A Google search for the terms Lansing and Mid Michigan turns up many hits that would lead one to believe that Lansing is a part of Mid Michigan Conversely a Google search for Lansing and Southern Michigan turns up mostly references where Lansing happens to be mentioned in the same work as a reference to something outside of the Lansing area in Southern Michigan There are a number of businesses and organizations based in Lansing with Mid Michigan in their title In the Lansing phone book I find at least 50 businesses listed whose name begins with Mid Michigan or Mid Michigan I find one whose name begins with Southern Michigan I would argue that the boundary between Mid or Central and Southern Michigan lies somewhere south of Lansing and somewhere just north of Jackson Perhaps Leslie Michigan Leslie is nearer the border I believe that once could safely draw the border to include all of Ingham County On these grounds I suggest that in the name of factual accuracy Lansing be moved at least in Wikipedia from Southern Michigan to Central Michigan for which Mid Michigan is said to be a synonym
