 But several of the cities have a much higher average income for residents and higher property values. Clarksville, Hendersonville, Murfreesboro, Smyrna, Spring Hill, etc. Their choice for the counties they selected is odd. Tipton County is relatively small, and the largest portion of Madison County is the city of Jackson. Also note, there are cities included in this comparison that are also responsible for the local school district, which is expensive, where Jackson is not.
