Kansas towns list more on the Register than most of the country (a typical Kansas town has 5.1 per 10,000 residents, the U.S. 2.4), so Iola’s 9.3 sits near the middle of its state (63% of Kansas towns have fewer) while its 5 historic buildings outnumber those of 70% of U.S. towns.

On January 1, 1859, a large meeting was held at the Deer Creek schoolhouse. The meeting decided to organize a town company, which was immediately done.
