In a speech unveiling her health care plan, Sen. Hillary Clinton said health insurance premiums “have almost doubled — up 80, no, 98 percent since 2000.”

That’s much higher than the rate of inflation. Is it true?

The number comes from two reports from the Kaiser Family Foundation and Health Research and Educational Trust, two groups that conduct an annual survey on employer health benefits. PolitiFact called Kaiser to make sure the methodologies for the two reports were the same, and Kaiser confirmed the 98 percent increase between 2007 and 2000 is correct.
