Ku Klux Klan Membership by State, 1915-1944*

created by Dylan Molnar

“Most disturbing perhaps is finding out that the political, social, and economic conditions that fostered the rise of the Ku Klux Klan in our region in the 1920s resonate with some similar processes and issues happening today,” – Susan Hardwick, August 2015.

This webmap shows Ku Klux Klan membership totals for 1915-1944. This data came from a project that I was assisting Susan Hardwick with before her untimely passing. In wake of the political climate, I find it important to release this information. Please contact me before you use this data.
Highest KKK membership as a percentage of the 1920 population:
1 Indiana
2 Oregon
3 Florida

*The KKK membership totals were determined by Jackson (1967) for all male and female persons initiated into the Klan between 1915 and 1944. The figures are estimates, based to some degree on the claims of William Joseph Simmons, Edward Young Clarke, Hiram Wesley Evans, and Robert L. Duffus, the estimates of the New York World, Washington Post, The New York Times, and The Imperial Night-Hawk, the evaluations of Charles Alexander, Emerson Loucks, and David Chalmers, and the report of the imperial kilgrapp at the 1924 Klonvocation.
