People who buy their own insurance report that their insurers most recently requested premium increases averaging 20 percent, according to a new Kaiser survey examining the experiences and views of people who buy health coverage in the non-group or individual market. Overall roughly three in four people (77 percent) with non-group coverage report facing a premium increase with a current or previous insurer. Most say they paid the increase, but 16 percent of all policyholders say they switched plans, either buying a less expensive policy from their current insurer or switching companies altogether. After these so-called “buy downs” are taken into account, people who faced a premium increase ended up paying 13 percent more than before.
