Middle-class workers are shouldering the brunt of the health insurance crisis, according to a new report released Wednesday by the nonpartisan Robert Wood Johnson Foundation.

The report “Barely Hanging On: Middle-Class and Uninsured” chronicles state-by-state health coverage trends, comparing 2008 and 2000.

Nationally, it found:

• $12,298 — the cost of a family insurance policy, up 56 percent.

• $4,386 — the cost of a single insurance policy, up 43 percent.

• $3,394 — the average employee contribution for family coverage when covered by employer, up 81 percent.

• $51,233 — the median household income, down 2.5 percent.

• 12 percent of private-sector employees work in businesses that do NOT offer health insurance, up 1.6 percent.

• 22 percent of employees were ineligible to participate in a company’s insurance plan, up 0.6 percent. Ineligibility includes length of time with company, hours worked and status.

• 13 million — the number of uninsured in the middle-class, up 2.4 percent.

• 43 million — the number of uninsured, up 1.7 percent.

In Kansas:

• $11,662 — the cost of a family insurance policy, up 56 percent.

• $4,197 — the cost of a single insurance policy, up 42 percent.

The report was released as part of “Cover the Uninsured Week,” which is this week, March 14-20. It considers middle-income as those earning between 200 and 399 percent of the federal poverty level. That’s between $44,000 and $85,000 for a family of four.
