Kansas ranked 33rd among the 50 states in a "corruption index" released last week by a Washington, D.C., newsletter.
Corporate Crime Reporter calculated the number of federal "public corruption" convictions of public officials in each state between 1993 and 2002, and indexed them according to each state's population.
Kansas had 51 such convictions during the time period, according to the newsletter, a rate of 1.87 convictions per 100,000 residents in the state.
Russell Mokhiber, the newsletter's editor, told the Journal-World the rankings were partly based on prosecutors' willingness to root out corruption.
"You can be the most corrupt state in the union, but if you don't have an active U.S. attorney willing to take on these cases, you're not going to show up in statistics," Mokhiber said.
He added: "I'm not sure that's true of Kansas."
Mississippi was named the most corrupt state. Nebraska was ranked the least corrupt. Kansas neighbors Missouri, Colorado and Oklahoma ranked 18th, 22nd and 46th, respectively.
