Economy

Commerce

In the 1870s, it was discovered that fluorspar, which is the industrial name for fluorite, was useful in removing impurities during the steel production process. This created a fluorite mining boom in this region of Southern Illinois. While fluorite is no longer mined in the U.S., the American Fluorite Museum, located in the former office building of the Rosiclare Lead and Fluoride Mining Company, holds memorabilia as a reminder of this era of local history. During the first week of October, Hardin County celebrates the Fluorspar Festival.

Income

Persons living below the poverty line, 13.1 percent, is a little higher than the rate in Illinois (12.5 percent) and a little less than the rate in the United States (13.4 percent).
