The study, released Thursday, was paid for by the Robert Wood Johnson Foundation, which funds health research and programs.
Researchers at the University of Minnesota’s State Health Access Data Assistance Center found that 64 percent of Kansans were insured through their employers in 2011, the latest information available, down from 73.9 percent in 2000.
Nationwide, 11.5 million fewer Americans get their insurance through the workplace in 2011 than in 2000.
The decline comes as insurance costs increase. Robert Wood Johnson Foundation CEO Risa Lavizzo-Mourey says higher costs lead to fewer employers offering insurance coverage and fewer employees accepting it when it’s offered.
