A new university report shows the number of Nebraska residents without health insurance surged between 2000 and 2010.

Researchers at the University of Nebraska Medical Center announced Tuesday that the population of uninsured Nebraskans younger than 65 increased by more than 67 percent during that decade.

The report found that nearly 15 percent of residents were uninsured in 2010, compared to 9 percent in 2000. Associate professor Jim Stimpson, who co-authored the report, says the growth reflects a trend in Midwestern states.

Researchers found that a majority of Nebraska's uninsured population lives above the federal poverty threshold, but one-third of the group does not have year-round, full-time employment. An estimated 40,000 are not U.S. citizens.
